Description

[0001] The present disclosure relates to a mammography system and a protective unit.

[0002] Mammography systems are used for the early detection and diagnosis of breast cancer and typically include an X-ray source, an X-ray detector, and a compression unit for positioning the breast during imaging. Modern mammography systems have a swiveling arm that carries the X-ray source and is rotated around a breast compressed by the compression unit during tomosynthesis imaging. This tomosynthesis technique allows for the creation of a three-dimensional image of the breast by capturing multiple projections from different angles.

[0003] To keep the patient's head out of the X-ray beam, mammography systems typically include a protective unit against which the patient can rest their head without directing it into the beam path. This protective unit, which typically includes a headrest and face shield, can be positioned on the mammography system in various ways.

[0004] The safety unit can also serve to ensure patient safety during a swiveling movement, for example, during tomosynthesis. The safety unit can be positioned in such a way as to prevent a collision between the swivel arm and the patient.

[0005] For example, the protective unit can be mounted on the swivel arm. In this configuration, the protective unit moves with the swivel arm during a swiveling motion. With this arrangement, a collision between the patient's head and the swivel arm can occur, especially during rapid swiveling movements of the arm during tomosynthesis.

[0006] Alternatively, the protective unit can be positioned on the compression unit. However, such a protective unit can lead to image artifacts, particularly at high flexion speeds and / or large tomosynthesis angles. This could only be prevented by a correspondingly large protective unit, which would then restrict patient positioning.

[0007] Alternatively, the protective unit can be permanently mounted on a stationary column of the mammography system. Optionally, the protective unit can be mounted via a height adjustment mechanism, such as a linear axis, allowing it to be adjusted in height to accommodate different patient sizes. This configuration is typically used with mammography systems that have a high rotation speed of the swivel arm during tomosynthesis and, optionally, a large tomosynthesis angle, to prevent collision risks. This reliably keeps the patient's head out of the swivel arm's range of motion. However, such a protective unit can hinder patient positioning for certain imaging techniques.For example, during a mediolateral oblique (MLO) mammogram, the fixed position of the protective unit on the column of the mammography system can prevent the patient from leaning back optimally according to the positioning recommendations, potentially resulting in an incomplete image of the breast. During a breast image taken with a magnification arrangement, also known as a magnification view, where the breast is positioned higher, the patient's head may collide with the protective unit fixed to the column, and the patient may not be optimally positioned. Particularly tall patients may be hampered by the fixed position of the protective unit on the column of the mammography system.

[0008] The objective problem to be solved is to provide a mammography system that both ensures patient safety through a stationary protective device and enables improved patient positioning for different types of imaging.

[0009] This objective problem is solved by a mammography system and a protective unit according to the independent claims. Advantageous features and further developments are listed in the dependent claims and in the following description.

[0010] Regardless of the grammatical gender of a particular term, persons with male, female or other gender identities are included.

[0011] The solution according to the invention is described below with respect to both the claimed mammography system and the claimed protective unit. Features, advantages, or alternative embodiments herein may be assigned to the other claimed subject matter and vice versa. In other words, the claims to a protective unit may be improved with features described or claimed in connection with a mammography system and vice versa.

[0012] The invention relates in a first aspect to a mammography system. The mammography system comprises a swivel arm, an X-ray source, and a protective unit. The swivel arm is designed to pivot the X-ray source. The protective unit is stationary. To prevent a collision between a patient and the swivel arm, the protective unit is positioned in a protective position. The protective unit comprises a removable and a fixed section. The removable section of the protective unit can be removed from the protective position.

[0013] The mammography system is a medical imaging system used to examine breast tissue. It can comprise various components configured to produce X-ray images of the breast. The mammography system can be a digital mammography system, an analog mammography system, or a tomosynthesis system. Other configurations include full-field digital mammography systems, breast CT systems, or combined mammography and ultrasound systems. The mammography system can be configured to perform various imaging procedures, such as two-dimensional mammography and / or three-dimensional tomosynthesis. It can be configured for the early detection of breast cancer, the diagnosis of breast diseases, or the monitoring of treatment progress.

[0014] The swivel arm can be designed as a movable mechanical structure for positioning the X-ray source relative to an X-ray detector and relative to the object being examined, in particular the patient or the patient's breast. The swivel arm is, in particular, rotatably mounted about an axis and can allow swiveling movements within various angular ranges.

[0015] The swivel arm for pivoting the X-ray source can be implemented using a mechanical linkage, a drive system, and control components. The swivel arm can position the X-ray source at various angular angles and can enable continuous or stepwise movement. The pivoting can be motorized or manual and can be monitored by encoders, sensors, or other position detection systems. The X-ray source pivoting can be configured to acquire images from different angles and can facilitate tomosynthesis or other three-dimensional imaging techniques.

[0016] The X-ray source is a device for generating X-rays. It may include an X-ray tube, an X-ray generator, and associated control components. The X-ray source can be configured to generate X-rays at different energy levels. It may be a tungsten anode tube, a molybdenum anode tube, or a rhodium anode tube. Additional components of the X-ray source may include filters, collimators, or radiation monitors. The X-ray source can be configured for controlled irradiation of breast tissue and can control various exposure parameters such as voltage, current, and exposure time.

[0017] The protective unit can be designed to protect a patient from a mechanical collision with the swivel arm. Additionally, the protective unit can be designed to prevent the patient from placing their head in the path of the X-ray radiation emitted by the X-ray source. The protective unit can have various geometric shapes and can be attached to different positions within the mammography system. Further embodiments of the protective unit may include adjustable components, padded surfaces, or ergonomic designs.

[0018] The stationary arrangement of the protective unit can be achieved through a fixed connection to an immobile part of the mammography system. The protective unit can be attached to a standing column, a housing, or another stationary component of the mammography system. The stationary arrangement can mean that the protective unit does not change its position while the swivel arm moves.

[0019] The stationary arrangement can be achieved using mechanical fasteners such as screws, clamps, or welded connections. This arrangement ensures that the protective unit maintains a constant protective function during the pivoting movement of the swivel arm.

[0020] Alternatively, the protective unit can be mounted on the stationary column via a height adjustment unit. This unit can include, in particular, a lifting carriage or a linear axis. The height of the protective unit can be adjusted via this unit, thus adapting it, for example, to the height of a patient. During a mammogram, and especially during movement of the swivel arm, the protective unit remains stationary, as the height adjustment only occurs during preparation for the mammogram, specifically during patient positioning.

[0021] The protective unit can be positioned in a protective position to prevent a collision between the patient and the swivel arm by strategically placing it between the patient and the moving swivel arm. The protective position can be chosen to separate the swivel arm's range of motion from the patient. This arrangement can create a physical barrier between the patient and the swivel arm. The protective position can also be chosen to keep the patient's head and other body parts outside the swivel arm's range of motion.

[0022] The removable section of the protective unit can be designed as a detachable or movable part that can be separated from or repositioned from the rest of the protective unit. The removable section may, for example, include a mechanical fastener such as a snap closure, a screw, or a bayonet fitting. Optionally, the removable section may include an ergonomic handle or marking to facilitate easy handling by medical personnel. The removable section may be connected to the fixed section of the protective unit by a detachable connection, a rotating connection, a sliding connection, and / or another movable mechanism.

[0023] Optionally, the removable section can be connected to the fixed section via multiple pins or arms for improved stability. The multiple pins can be cylindrical or conical connectors on the fixed section that engage in corresponding receptacles in the removable section, and / or vice versa. The pins can have different diameters and lengths and be made of metal or reinforced plastic. The arms can be elongated connectors that create a larger contact area between the removable and fixed sections. Using multiple attachment points reduces the mechanical stress on individual connection points and increases the overall stability of the connection. Multiple attachments prevent unwanted movement of the removable section during the examination and ensure precise positioning.

[0024] The removable section can include various components such as a face shield, headrest, or other patient protection elements. The removable section can be made of the same or different materials as the rest of the protective unit.

[0025] The fixed section of the protective unit can be designed as the part of the protective unit that remains permanently attached to the mammography system. The fixed section can form the structural base of the protective unit and can facilitate attachment to the stationary part of the mammography system. The fixed section can be made of robust materials and can have a permanent connection to the mammography system. The fixed section can provide various attachment points for the removable section.

[0026] Removing the removable section from its protective position can be achieved through various mechanisms. Removal may involve completely separating the removable section from the protective unit and / or moving the removable section from its original protective position. Removal can be accomplished by releasing a connecting element, rotating it around a hinge, or sliding it along a guide. Removal can allow for a temporary or permanent change in position and can be configured to improve patient positioning or to perform specific examination procedures. Removal can be performed manually by medical personnel or operators, or automatically by a control system. Removal can be temporary, allowing the removable section to be repositioned in its protective position after patient positioning or completion of the imaging procedure.

[0027] In embodiments of the invention, the various components of the mammography system can interact technically with one another to enable safe and efficient imaging. For example, the swivel arm can be equipped with a sensor that monitors the position of the protective unit. The mammography system can include a safety interlock that prevents the swivel arm from moving if the protective unit is not properly positioned. The X-ray source can only be activated when all safety conditions are met.

[0028] The mammography system with a removable section of the protective unit offers technical advantages by ensuring both patient safety and examination flexibility. The combination of a stationary protective unit and a removable section prevents a patient from colliding with the swivel arm, while simultaneously allowing optimal patient positioning for various imaging types, particularly those where there is no risk of collision because the swivel arm is stationary. This mammography system also reduces examination time, as medical personnel can quickly adjust the position of the protective unit without removing the entire device.

[0029] In an optional embodiment, the removable section can be telescopically extendable and retractable. This telescopic design allows for stepless adjustment of the face shield's position along a linear axis. The removable section can comprise several telescoping segments that can be fixed in various positions by friction, locking mechanisms, or screw connections. The telescopic movement can be performed manually by the operator or automatically by a drive mechanism. Advantageously, the telescopic design enables precise positioning of the face shield according to the patient's height and the requirements of different imaging techniques or types.

[0030] In one embodiment of the mammography system, the removable section of the protective unit can include a face shield.

[0031] The face shield can be designed as a component intended to protect and position a patient's face during a mammography examination. It can be a flat structure that provides a support surface for the patient's face. Face shields can be made from various materials, such as plastic, metal, or a composite material. They can have a rectangular, square, or ergonomically shaped geometry adapted to the contours of the human face.

[0032] Face shields can take various forms. They can be flat or curved, conforming to the natural shape of the face. Face shields may also include a padded surface to enhance patient comfort during the examination. This padded surface can be made of soft materials such as foam, silicone, or fabric.

[0033] The face shield can be referred to as a face guard, face support, head support, or patient protection.

[0034] The face shield can optionally be available in different sizes to accommodate varying patient sizes. It can also optionally include an adjustable component to adapt to different face shapes. Furthermore, the face shield can feature markings or guide lines to assist medical personnel in correctly positioning the patient. Optionally, the face shield can be constructed from a radiation-absorbing material designed to block X-rays and protect the patient's face from unwanted radiation exposure.

[0035] The face shield can be designed to provide a defined position for the patient's head. By positioning the head against the face shield, it can be ensured that the head remains outside the range of motion of the swivel arm. At the same time, the face shield can help minimize patient movement during the examination, which can lead to improved image quality.

[0036] By removing the removable section of the protective unit from the protective position, the face shield can be moved out of the way for certain types of examinations, such as MLO or magnification images, without having to disassemble the entire protective unit.

[0037] Advantageously, the design of the removable section with a face shield allows for flexible adaptation of the mammography system to different examination types and patient sizes, while simultaneously ensuring patient protection.

[0038] In another embodiment of the mammography system, the removable section of the protective unit can be the face shield.

[0039] In this embodiment, the face shield itself forms the removable section of the protective unit, thus enabling a simplified design. The description "where the removable section of the protective unit is the face shield" describes a specific structural configuration in which the face shield is not merely a part of the removable section, but rather constitutes the entire removable section. This design can create a direct identity between the removable section and the face shield. The face shield can therefore be designed as an independent, removable component that can be attached directly to the fixed section of the protective unit. This configuration can represent a particularly simple and efficient solution, as no additional intermediate elements are required between the fixed section and the face shield.

[0040] The face protection can be designed as described above.

[0041] Structural simplification can offer several technical advantages. The face shield can be designed as an integrated unit, combining both the protective function and the removable mechanism in a single component. This design can reduce the number of moving parts and thus decrease the mechanical complexity of the mammography system. Furthermore, directly integrating the removable section as the face shield can improve the stability and reliability of the connection between the fixed and removable sections.

[0042] In another embodiment of the mammography system, the removable section of the protective unit can be arranged in the protective position via a detachable connection to the fixed section of the protective unit. The removable section of the protective unit can be removed from the protective position by releasing the detachable connection.

[0043] The detachable connection can be designed as a mechanical fastening device that allows for a temporary and reversible attachment between two components. The detachable connection can be designed to ensure secure fastening during normal operation while simultaneously allowing for the intentional separation of the connected components. The detachable connection can incorporate various mechanical fastening elements that enable controlled separation.

[0044] The detachable connection can be designed, for example, as a plug connection, quick-release fastener, bayonet fitting, screw connection, clamp connection, snap-fit ​​connection, magnetic connection, or a combination thereof. The detachable connection can, for example, be designed as a plug connection with a plug pin and a corresponding receptacle, wherein the plug pin can be inserted into the receptacle and optionally secured by a rotary motion or a locking mechanism. Alternatively, the detachable connection can be designed as a quick-release fastener that can be released by actuating a lever or button. The detachable connection can also be designed as a threaded screw connection, wherein the connection can be released by turning. Another alternative embodiment can include a clamp connection with a spring element or a snap-fit ​​connection with locking lugs and corresponding recesses.

[0045] The detachable connection can be positioned in such a way as to allow easy operation by an operator, while at the same time preventing unintentional detachment during operation.

[0046] The release of a detachable connection can be a mechanical process in which the fastening between the removable and fixed sections is released. Release can be achieved through various actuation methods, such as turning, pulling, pushing, sliding, or levering. It may require manual operation by an operator, applying a defined force or movement. Alternatively, release can be achieved by actuating a release mechanism that disengages the connection. The release process can be designed to ensure a controlled and safe separation of the components. The release mechanism can be reversible, allowing the connection to be re-established after separation.

[0047] The detachable connection can be designed to allow tool-free operation by the operator. Alternatively, the detachable connection can require tool operation to prevent unintentional disconnection during the examination. Furthermore, the detachable connection can be equipped with safety mechanisms that prevent accidental disconnection during operation of the mammography system.

[0048] The arrangement of the removable section via the releasable connection in the protective position allows for a defined spatial positioning of the removable section relative to the fixed section. The protective position can be defined such that the removable section can fulfill its intended protective function while simultaneously ensuring secure fastening. The releasable connection can be designed so that the removable section assumes a stable and reproducible position in the protective position. The connection can include positioning aids or guide elements that support correct alignment of the removable section in the protective position.

[0049] Removing the removable section from its protective position may allow for a spatial displacement of the removable section from its original position. Removal may involve a complete separation of the removable section from the fixed section, whereby the removable section can be physically detached from the mammography system. Removal may also involve displacing the removable section to a different position, in which the protective function is temporarily suspended. The removal mechanism may be designed to allow improved accessibility for patient positioning, particularly for MLO or magnification examinations.

[0050] Advantageously, the detachable connection allows for complete removal of the removable section from the examination area, thus achieving maximum flexibility in patient positioning. This is particularly beneficial for large patients or in special examination protocols where the removable section would otherwise hinder positioning. At the same time, the detachable connection ensures a secure, stable, and reproducible attachment of the removable section during normal examinations, maintaining patient safety during rapid tomosynthesis movements at large angles.

[0051] In another embodiment of the mammography system, the removable section of the protective unit can be arranged on the fixed section of the protective unit via a sliding connection. The removable section of the protective unit can be removed from the protective position along the sliding connection. The sliding connection can be designed such that the removable section of the protective unit is slidable parallel to a pivot plane of the swivel arm.

[0052] The sliding connection can be designed as a mechanical linkage device that enables linear movement between two components. The sliding connection can incorporate various technical implementations, such as a rail system, a sliding guide, a telescopic connection, or a linear guide. Furthermore, the sliding connection can be designed as a tongue-and-groove system, where one component has a groove and the other component includes a corresponding projection or spring. Additionally, the sliding connection can include a ball bearing, a roller bearing, and / or a plain bearing to enable low-friction movement. The sliding connection can also optionally include a locking mechanism that allows the removable section to be fixed in a specific position.Synonyms or alternative terms for sliding connection include sliding connection, sliding connection, linear connection, or movable connection. The sliding connection is directly related to the removable and fixed sections of the protective unit by allowing controlled movement of the removable section relative to the fixed section.

[0053] Removing the removable section of the guard unit along the sliding connection can be a directed movement, where the removable section of the guard unit is moved in a predefined direction. This movement can be performed manually by an operator or automatically by a drive mechanism. Furthermore, removal along the sliding connection can include various types of movement, such as continuous sliding, incremental movement, or movement at variable speed. Additionally, removal along the sliding connection can be supported by guide elements that ensure precise and stable movement. The movement can also be controlled by damping elements to prevent abrupt movements. Alternative terms for removal along the sliding connection include shifting, sliding, moving, or propelling.Removing the device along the sliding connection is directly related to the protective position, as it allows the removable section to be moved out of this position to enable improved patient positioning.

[0054] The pivot plane of the swivel arm can be defined as a geometric plane in which the swivel arm moves during its operation, particularly during tomosynthesis. The pivot plane can be defined by the trajectory of the swivel arm during a tomosynthesis scan. Specifically, the pivot plane can have a vertical orientation. Synonyms or alternative terms for the pivot plane include plane of rotation, plane of motion, plane of rotation, or pivot range. The pivot plane of the swivel arm is directly related to the sliding connection, as aligning the sliding connection parallel to this pivot plane enables coordinated movement between the removable section and the swivel arm. Furthermore, this parallel arrangement ensures that the removable section never collides with the pivot plane and thus potentially with the swivel arm.

[0055] The parallel alignment of the sliding connection to the pivot plane of the swivel arm can be defined as a geometric relationship in which the direction of movement of the sliding connection lies in a plane parallel to the pivot movement of the swivel arm. Specifically, the direction of movement of the sliding connection lies outside the pivot plane. This parallel alignment ensures that the removable section of the protective unit cannot collide with the swivel arm at any position along the sliding connection.

[0056] Parallel displacement can be performed horizontally, with the removable section being moved laterally out of the protective position. Alternatively, parallel displacement can be performed in an oblique direction parallel to the pivot plane to achieve optimal release of the patient positioning area. The displacement direction can be selected to maximize freedom of movement for patient positioning while maintaining the structural integrity of the protective unit.

[0057] Optionally, the removable section can be moved along a circular arc path away from the swivel arm and towards the patient as it slides along the sliding connection. This circular arc movement follows a defined radius, chosen to ensure that the removable section maintains a constant distance from the swivel arm during the pivoting motion. The circular arc movement can be achieved using a curved guide rail, a swivel arm with a fixed pivot point, and / or a combination of several joints. The circular arc path can, for example, cover an angular range of 30° to 180°, with the removable section being lockable in various angular positions.

[0058] Advantageously, the sliding connection allows for simple and intuitive operation of the protective unit, as the linear movement is easily understood and executed by the operator. Furthermore, the parallel alignment to the pivoting arm's plane of rotation ensures efficient release of the patient positioning area without compromising the protective function of the unit. In addition, the sliding connection maintains a stable mechanical connection between the fixed and removable sections, even when the removable section is moved out of the protective position. Moreover, the removable section of the protective unit can remain connected to the fixed section even when removed from the protective position. This can improve the handling of the mammography system, as no storage areas are required and the removable section cannot be misplaced.

[0059] In another embodiment of the mammography system, the removable section of the protective unit can be arranged on the fixed section of the protective unit via a rotatable connection. The removable section of the protective unit can be removed from the protective position by rotating it around the rotatable connection.

[0060] The rotatable connection can be designed as a mechanical connecting element that allows rotational movement between two components. The rotatable connection can encompass various technical embodiments, such as a hinge, a joint, a pivot pin, a ball bearing, a needle bearing, and / or a swivel bearing. Furthermore, the rotatable connection can be designed as a pin-and-socket connection, a journal connection, or a bearing connection with rolling elements. In addition, the rotatable connection can include a friction element or a locking mechanism to fix a specific rotational position or to control the rotational movement. Such a locking mechanism can be designed as a detent mechanism, a clamping device, or a screw connection.Additionally, the rotatable connection may include a spring device that provides a restoring force to return the removable section to the protective position, particularly when the locking mechanism is released.

[0061] The rotatable connection can be equipped with stops or limits to define the rotation range. These limits can include mechanical stops, detents, or other locking mechanisms.

[0062] Rotation around a swivel joint can be understood as a rotational movement around a defined axis of rotation. This rotation can be continuous or in discrete steps. Furthermore, the rotation can be performed manually by an operator or automatically by a drive mechanism. In the case of manual operation, the swivel joint can be equipped with a handle or grip to allow for ergonomic operation. In an automated version, an electric motor, a pneumatic drive, or a hydraulic drive can effect the rotation. The rotation can encompass various angles, such as 90 degrees, 180 degrees, or a complete 360-degree rotation. Additionally, rotation can be possible in both directions, thus enabling bidirectional movement.The rotation can also be performed at a defined speed or with controlled torque to ensure precise positioning.

[0063] The arrangement of the removable section via a rotatable connection to the fixed section can encompass various design configurations. The rotatable connection can be positioned at different locations between the fixed and removable sections, for example, at one end, in the middle, or at multiple points along the connection. Furthermore, the rotatable connection can be designed to have one or more axes of rotation, thus enabling complex movement patterns. The arrangement can also include additional guide or support elements to ensure stability during rotation.

[0064] Removing the removable section from its protective position by rotating it can be understood as a deliberate movement in which the removable section is moved away from the protective position. This movement can serve to improve access for patient positioning or to avoid a collision. The removal can be temporary. Furthermore, the removal can involve various end positions in which the removable section is positioned outside the protective position and, in particular, outside the range of motion of the patient or the mammography components.

[0065] The rotatable connection to the protective unit offers several technical advantages. Its rotational capability allows for flexible adjustment to different patient sizes and examination types. Furthermore, the rotatable connection enables quick and easy repositioning of the removable section without requiring complete disassembly. Additionally, the removable section of the protective unit can remain connected to the fixed section even when removed from its protective position. This improves the handling of the mammography system, as no storage space is required and the removable section is not misplaced.

[0066] In another embodiment of the mammography system, the rotatable connection can include a vertical axis of rotation.

[0067] The vertical axis of rotation can be designed as an axis of rotation extending vertically and oriented perpendicular to a horizontal plane. The vertical axis of rotation can run parallel to the direction of gravity and allows for rotational movement of the removable section of the protective unit in a horizontal plane. The vertical orientation of the axis of rotation can be characterized by the axis assuming an upright position and extending from bottom to top or from top to bottom.

[0068] The rotational movement around the vertical axis of rotation allows the removable section of the protective unit to rotate in a horizontal plane. This rotational movement can cause the removable section to pivot laterally to the left or right. The angle of rotation can be variable and, for example, 90 degrees, 180 degrees, or any other desired angle.

[0069] Alternative terms for the vertical axis of rotation include vertical axis of rotation, upright axis of rotation, perpendicular pivot axis, or vertical pivot axis. The vertical axis of rotation can also be referred to as the Z-axis in a Cartesian coordinate system.

[0070] The rotatable connection with a vertical axis of rotation can encompass various technical designs. The rotatable connection can be designed as a pin, bolt, stud, or shaft guided in appropriate bearings or bushings. The bearing arrangement can be a hinge, pivot bearing, plain bearing, roller bearing, or ball bearing. The rotatable connection can also be designed as a pin-and-socket connection, in which a cylindrical pin is supported in a corresponding bushing, allowing rotation about the pin's longitudinal axis. The rotatable connection can be made of various materials, such as steel, stainless steel, aluminum, or plastic. The surface of the rotatable connection can be coated or treated to reduce friction and minimize wear. The rotatable connection can have different diameters, depending on the mechanical requirements and the forces to be transmitted.The diameter can vary from a few millimeters to several centimeters. The length of the rotatable connection can be dimensioned according to the thickness of the components to be joined.

[0071] The vertical axis of rotation is directly related to the rotating connection and enables its functionality. The vertical orientation of the axis of rotation can be particularly advantageous because it allows for intuitive movement of the removable section of the guard unit, corresponding to the natural movement an operator would use to pivot components to the side. Furthermore, the vertical axis of rotation ensures stable storage, as gravity holds the components in position, eliminating the need for additional retaining mechanisms to counteract gravity.

[0072] In another embodiment of the mammography system, the rotatable connection can be arranged centrally in the protective unit.

[0073] A central arrangement of the rotatable connection refers to a positioning of the rotatable connection in a central area of ​​the protective unit, wherein the rotatable connection is positioned between the outer edges or boundaries of the protective unit. In particular, a central arrangement means that the rotatable connection is arranged centrally in the horizontal direction within the protective unit.

[0074] The central positioning of the rotatable connection can be achieved through various mechanical implementations. The rotatable connection can be designed as a pivot joint, hinge, pivot pin, or rotary bearing, with these components integrated in the central position of the protective unit. Furthermore, the central positioning can be achieved using fasteners such as screws, bolts, or pins that fix the rotatable connection in the central position of the protective unit. The rotatable connection can also include bearings, bushings, or sliding surfaces that enable low-friction rotation in the central position.

[0075] Alternative terms for central arrangement include central arrangement, centered positioning, symmetrical arrangement, or balanced positioning. Central arrangement can also be referred to as middle position, central position, or balanced position.

[0076] Advantageously, the central arrangement of the rotating connection can offer an optimal balance between stability and mobility of the removable section of the protective unit. The central positioning allows for even force distribution during rotation, thereby reducing the mechanical stress on the connecting elements. Furthermore, the central arrangement enables intuitive and ergonomic operation for medical personnel, as the rotational movement occurs around a central point.

[0077] In another embodiment of the mammography system, the rotatable connection can be arranged on one or both sides of the protective unit.

[0078] The unilateral arrangement of the rotatable connection can be configured in such a way that the rotatable connection is positioned on a single side of the protective unit. This unilateral arrangement can be configured as a left-sided or right-sided arrangement, depending on the specific orientation of the mammography system and the patient positioning requirements. A unilateral arrangement can offer advantages in terms of the simplicity of the mechanical design and can be less expensive to manufacture. Furthermore, a unilateral arrangement can allow for asymmetrical movement of the removable section, enabling the removable section to be rotated in a preferred direction. Synonyms for unilateral arrangement include unilateral positioning or one-sided positioning.

[0079] The double-sided arrangement of the rotatable connection can be configured with rotatable connections on both the left and right sides of the guard unit. In other words, a rotatable connection is located on each side of the guard unit. This double-sided arrangement can be configured as a symmetrical or bilateral arrangement. A double-sided arrangement can also allow symmetrical movement of the removable section, enabling it to rotate equally in both directions. Each of the two rotatable connections can have its own vertical axis of rotation. The removable section can be selectively rotated around one of the two rotatable connections while the other rotatable connection is released or disengaged. In the double-sided arrangement, the rotatable connections are disengageable, unhookable, or releasable.In other words, when the rotating joint on one side of the guard unit is rotated, the other rotating joint on the opposite side of the guard unit is released to allow the rotation. This configuration enables bidirectional movement of the removable section, allowing the removable section of the guard unit to be moved from the guard position to either the left or the right. The arrangement of the rotating joints on both sides can be symmetrical. The two rotating joints can have identical design features and be arranged as mirror images of each other. Alternatively, the two rotating joints can allow different angles of rotation or ranges of movement to meet various positioning requirements.

[0080] The sides of the protective unit can be referred to as the left and right sides, based on the perspective of an observer looking towards the mammography system. The sides of the protective unit can provide structural attachment points for the rotating linkage and may include reinforced areas to absorb mechanical stresses during rotation. The sides may also include guide elements or stops to limit the range of motion of the rotating linkage.

[0081] The lateral placement of the rotating connection allows for improved flexibility in patient positioning. The removable section can be moved to the appropriate side depending on the patient's size and the type of examination. Positioning the rotating connection on one or both sides of the protective unit offers the technical advantage of increased adaptability of the mammography system to different patient requirements and examination protocols. The flexible positioning of the face shield improves patient comfort and enables optimized image quality through improved patient positioning.

[0082] In another embodiment of the mammography system, the rotatable connection can include a horizontal axis of rotation. The horizontal axis of rotation can be aligned perpendicular to a pivot plane of the swivel arm.

[0083] The horizontal axis of rotation can be designed as a rotational axis that runs parallel to the Earth's surface and enables rotational movement around this horizontal orientation. Synonyms or alternative terms for the horizontal axis of rotation include horizontal axis of rotation, horizontal pivot axis, horizontal swivel axis, or horizontal pivot axis.

[0084] The pivot plane is defined as described above.

[0085] The alignment perpendicular to a pivot plane can be configured as a geometric orientation where the horizontal axis of rotation forms a right angle of 90 degrees to the pivot plane of the swivel arm. This perpendicular alignment of the horizontal axis of rotation to the pivot plane of the swivel arm enables a specific kinematics of the rotatable connection, allowing the removable section of the protective unit to move in a plane parallel to the pivot plane of the swivel arm.

[0086] By aligning the axis of rotation horizontally, perpendicular to the pivot plane, the removable section of the protective unit can be pivoted or rotated upwards. In other words, the removable section of the protective unit can be rotated around the axis of rotation so that it points vertically upwards or to the side instead of vertically downwards.

[0087] The rotatable connection with the horizontal axis of rotation can incorporate various technical implementations, such as a hinge, joint connection, pivot bearing, or roller bearing. The rotatable connection can be designed as a mechanical rotary bearing with bushings, ball bearings, or plain bearings. Furthermore, the rotatable connection can be implemented as a bolt connection, pin connection, pivot connection, or as an integrated pivot axis within a plastic or metal component. Optionally, the rotatable connection can be designed with a detent or locking mechanism that allows for discrete angular positions of the removable section. The rotatable connection can also be equipped with a damping mechanism to ensure controlled movement of the removable section.

[0088] Optionally, the fixed section can include a slot into which the removable section can be screwed when it has been removed from the protective position by rotating it around the rotatable connection.

[0089] Optionally, the rotating connection can include a rotary knob that can integrate a logo or a camera for automated patient height detection. The rotary knob is designed as a manually operated control element, which, when turned, rotates the removable section around the rotating connection. The logo can be embossed, printed, or used as a separate element within the rotary knob, serving as a company logo or product identifier. The camera can be a digital image acquisition unit connected to an image processing system. The camera can automatically detect the patient's height and adjust the mammography system accordingly. Integrating the camera into the rotary knob allows for discreet positioning and protects the camera from damage.

[0090] Advantageously, the horizontal axis of rotation, aligned perpendicular to the pivot plane of the swivel arm, allows for intuitive and ergonomic movement of the removable section of the guard unit. This arrangement enables a natural upward or sideways pivoting motion that is easy for the operator to handle while effectively clearing the patient positioning area. In particular, the removable section of the guard unit remains connected to the fixed section when removed from the guard position. This simplifies handling when removing the removable section from the guard position. Furthermore, it ensures that removing the removable section from the guard position does not impede the movement of the swivel arm, as the removable section is removed in a plane parallel to the pivot plane.

[0091] In another embodiment of the mammography system, the rotatable connection can include a horizontal axis of rotation. The horizontal axis of rotation can be aligned parallel to a pivot plane of the swivel arm.

[0092] The horizontal axis of rotation can be designed as an axis of rotation extending in a horizontal direction around which the removable section of the protective unit can be rotated. A horizontal axis of rotation can be defined as an axis extending parallel to the Earth's surface or to a reference plane of the mammography system. In particular, the horizontal axis of rotation is aligned parallel to the pivot plane of the swivel arm. The horizontal axis of rotation is located outside the pivot plane.

[0093] The pivot plane of the swivel arm is defined as described above.

[0094] The parallel alignment of the axis of rotation can allow the removable section of the protective unit to be rotated in a direction perpendicular to the pivot plane of the swivel arm.

[0095] The rotatable connection with a horizontal axis of rotation aligned parallel to the pivot plane can incorporate various technical implementations. The rotatable connection can be designed as a hinge that allows rotation around the horizontal axis. The hinge can include bearings, bushings, or other rotating elements that enable low-friction rotation. Alternatively, the rotatable connection can be designed as a pin or bolt that passes through corresponding receptacles in the fixed and removable sections of the protective unit.

[0096] When the removable section is removed from its protective position, it folds upwards around the axis of rotation. The horizontal axis of rotation can be positioned to allow the removable section to rotate upwards or downwards. This rotation can move the face shield out of the patient's positioning area without the removable section protruding laterally from the system.

[0097] The horizontal pivot axis can be positioned at various locations within the protective unit. It can be located at the front, allowing the removable section to be folded upwards. Alternatively, it can be positioned at the rear, enabling a different folding motion. The position of the horizontal pivot axis can influence the movement characteristics of the removable section.

[0098] Parallel alignment to the pivot plane can offer several advantages. This alignment allows the removable section of the protective unit to be folded up or down, thus providing improved access for patient positioning. This direction of movement can be particularly beneficial for MLO or magnification views where free positioning of the patient's head is required.

[0099] In another embodiment of the mammography system, the fixed section can include an adjustment axis. The rotatable connection can be displaceable along this adjustment axis. The protective unit can also include a slider. The slider can be arranged on the fixed section via a first rotatable connection. The slider can also be arranged on the removable section of the protective unit via a second rotatable connection. By actuating the slider, the removable section of the protective unit can be removed from its protective position.

[0100] The adjustment axis can be designed as a linear guide structure located on the fixed section of the guard unit, enabling directed movement of the rotatable connection. The adjustment axis can be designed as a rail, groove, slot, or guide channel along which the rotatable connection is slidably mounted. The adjustment axis can be oriented vertically, horizontally, or at an oblique angle, depending on the desired direction of movement of the removable section. The adjustment axis can be made of various materials, such as metal, plastic, or composite materials, that possess sufficient mechanical strength and wear resistance.

[0101] The adjustability of the rotatable connection along the adjustment axis can be achieved through various guide mechanisms. The rotatable connection can include a sliding element, a roller element, or a ball bearing that is movable along the adjustment axis. This adjustability allows for controlled linear movement of the rotatable connection while simultaneously maintaining its rotational capability. The combination of linear adjustability and rotational capability enables a complex trajectory of movement for the removable section.

[0102] The slider can be designed as a manually operated control element that allows coordinated movement of the removable section of the protective unit. The slider can be designed as an elongated element, lever, handle, or operating rod. The slider can be ergonomically shaped to allow for easy handling by the operator. The slider can be made of various materials, such as plastic, metal, or a composite material.

[0103] The slide can be arranged on the fixed section via the first rotatable connection. The first rotatable connection can be designed, for example, as a hinge, pivot, joint, or pivot bearing, allowing rotational movement of the slide relative to the fixed section. The first rotatable connection can include a horizontal axis of rotation. In particular, the axis of rotation of the first rotatable connection of the slide can be parallel to the pivot plane of the pivot arm.

[0104] The slide can be arranged on the removable section of the protective unit via the second rotatable connection. The second rotatable connection can be designed analogously to the first rotatable connection and allow rotation of the slide relative to the removable section. The second rotatable connection can include an axis of rotation aligned parallel to the axis of rotation of the first rotatable connection.

[0105] By actuating the slide, the removable section of the guard unit can be removed from its protective position. Actuating the slide can be a manual movement, such as pushing, pulling, or sliding. When the slide is actuated, it rotates relative to the fixed section around the first pivot point and simultaneously around the second pivot point relative to the removable section. This coordinated rotation causes the pivot point to move along the adjustment axis and the removable section to rotate around the pivot point relative to the fixed section.

[0106] The combination of adjustment axis, rotating connection, and slider enables a garage door-like movement of the removable section. During this movement, the removable section is pushed upwards and simultaneously rotated around the rotating connection, allowing it to be moved into a position above the fixed section. This kinematic design allows for space-saving storage of the removable section while ensuring simple and intuitive operation by the operator. Advantageously, this design enables controlled and stable movement of the removable section from its protective position. The slider can serve as a central operating element, allowing the complex movement of the removable section to be controlled with a simple hand movement.Furthermore, the removable section of the protective unit can remain connected to the fixed section even when removed from its protective position. This can improve the handling of the mammography system, as no storage surfaces are required and misplacement of the removable section is prevented.

[0107] In a further embodiment of the mammography system, the removable section of the protective unit can be arranged on the fixed section of the protective unit via at least one connecting piece. The connecting piece can be connected to the fixed section of the protective unit via a first rotatable connection. The connecting piece can be connected to the removable section of the protective unit via a second rotatable connection. The removable section of the protective unit can be pivoted relative to the fixed section of the protective unit via the connecting piece such that the removable section of the protective unit can be removed from the protective position.

[0108] The connector can be designed as a mechanical coupling element that enables a movable connection between the fixed and removable sections of the protective unit. The connector can be rigid or flexible and may take various geometric forms, such as a rod, arm, lever, articulated arm, or hinge. It can be made of various materials, such as metal, plastic, or composites, that provide sufficient mechanical strength and durability for medical applications. Alternatively, the connector may be referred to as an articulated arm, swivel arm, connecting arm, or coupling piece. The connector can have an elongated shape and be positioned between the fixed and removable sections of the protective unit to allow controlled movement of the removable section.

[0109] The connecting piece can be connected to the fixed section of the protective unit via a first rotatable joint. This first rotatable joint can incorporate various designs, such as a ball joint, a cylindrical joint, a hinge joint, a universal joint, a hinge, and / or a swivel bearing, which allow rotation of the connecting piece relative to the fixed section. The first rotatable joint can include a bearing element, such as a ball bearing, a plain bearing, or a bushing, to ensure low-friction rotation. The axis of rotation of the first rotatable joint can be oriented vertically, horizontally, or at any angle, depending on the desired direction of movement of the connecting piece. Advantageously, the axis of rotation is horizontal and parallel to the plane of rotation but outside the plane of rotation.The first rotatable connection may also include a locking mechanism or detent position to fix the connector in certain angular positions.

[0110] The connecting piece can be linked to the removable section of the protective unit via a second rotatable connection. This second rotatable connection can be designed analogously to the first. The second rotatable connection can have a different axis of rotation orientation than the first to allow for complex movement patterns of the removable section. Advantageously, the axis of rotation of the second rotatable connection is aligned parallel to the axis of rotation of the first rotatable connection.

[0111] The removable section of the protective unit can be pivoted relative to the fixed section of the protective unit via the connecting piece, allowing it to be removed from the protective position. This pivoting capability can be achieved through coordinated movement around the first and second rotatable links, enabling the removable section to be moved into various positions. The pivoting motion can be upward, sideways, or a combination of both. The connecting piece can be designed as a parallel guide to ensure controlled and stable movement of the removable section.

[0112] The pivoting mechanism allows the removable section to be moved out of the patient's positioning area without completely separating it from the protective unit. This configuration can improve workflow efficiency, as the removable section can be quickly repositioned without requiring assembly or disassembly. Advantageously, the arrangement of the removable section via at least one connecting piece with two pivoting links enables controlled and stable movement of the removable section out of the protective position. The double pivot connection allows for precise positioning of the removable section while maintaining the structural integrity of the protective unit.Furthermore, this configuration can allow for easy operation by medical personnel, as the removable section can be moved into the desired position with simple hand movements.

[0113] In a further embodiment of the mammography system, the removable section of the protective unit can be arranged on the fixed section of the protective unit via two connecting pieces. Each connecting piece can be connected to the fixed section of the protective unit via a first rotatable connection. Each connecting piece can also be connected to the removable section of the protective unit via a second rotatable connection. The removable section of the protective unit can be pivoted relative to the fixed section of the protective unit via the connecting pieces in such a way that the removable section of the protective unit can be removed from its protective position.

[0114] The connecting pieces, as well as the first and second rotatable connections, can be designed as described above.

[0115] The two connecting pieces can be aligned parallel to each other. This means that, in particular, the axes of rotation of the first and second rotatable connections can be aligned parallel to each other.

[0116] The removable section of the guard unit can be pivoted relative to the fixed section via the connecting links, allowing it to be removed from the guard position. Pivoting can be achieved by simultaneous or sequential rotation around the first and second pivoting links. The connecting links can form a parallelogram linkage, a scissor linkage, or another type of joint linkage. Pivoting can result in linear, circular, or a combined movement of the removable section. Pivoting can be performed manually by an operator or automatically by actuators. The connecting links can include guide rails, stops, or limits to control the movement. Furthermore, the connecting links can incorporate spring mechanisms or counterweights to assist or stabilize the pivoting action.

[0117] The removable section can be pivoted in various directions. It can be removed from its protective position upwards, sideways, or in a combined movement, specifically by pivoting. The specific direction of movement is determined by the orientation of the pivot axes of the rotatable connections. With a vertical orientation of the pivot axes, the removable section can be pivoted horizontally to the side. With a horizontal orientation of the pivot axes, the removable section can be pivoted vertically upwards or downwards.

[0118] This design enables precise and controlled movement of the removable section through the double joint connection. The two connecting pieces offer increased stability and guidance accuracy compared to a single joint connection. Furthermore, the parallel guidance provided by the two connecting pieces allows for smooth movement without tilting or jamming.

[0119] In a further embodiment of the mammography system, the removable section can comprise a first and a second removable section. The first removable section of the protective unit can be arranged in the protective position via a detachable connection to the fixed section of the protective unit. The first removable section and the second removable section of the protective unit can be removed from the protective position by releasing the detachable connection. The second removable section of the protective unit can be arranged on the first removable section of the protective unit via a rotatable connection. The second removable section of the protective unit can be removed from the protective position by rotating it about the rotatable connection.

[0120] The first removable section can be designed as a structural element of the protective unit, forming a sub-component of the removable section. The first removable section can be designed as an intermediate element between the fixed section and the second removable section. The first removable section can have various geometric shapes, such as an elongated, curved, or angled structure. The first removable section can be made of various materials, such as plastic, metal, or composites. The first removable section can include mechanical fasteners, guide structures, or connection interfaces. The first removable section can serve as a support structure for the second removable section while simultaneously providing a connection to the fixed section.

[0121] The second removable section can be designed as an additional structural element of the protective unit, representing an additional component of the removable section. The second removable section can be configured as the distal element of the protective unit, positioned closest to the patient. The second removable section can include the face shield or be directly connected to it. Alternatively, the second removable section can be formed by the face shield. The second removable section can have various dimensions and shapes to accommodate different patient sizes and positioning requirements. The second removable section can include interchangeable components or customizable surfaces. The second removable section can be designed as a movable element that can be positioned independently of the first removable section.

[0122] In particular, the removable section is divided into a first and a second removable section. This division can be designed as a structural segmentation of the removable section into two separate functional units. The division can allow for a physical separation between the first and second removable sections. It can also enable a modular design of the protective unit, where different components can be individually removed or repositioned. Finally, the division can serve as a design strategy to improve the flexibility and adaptability of the protective unit.

[0123] The detachable connection and the rotatable connection are designed, in particular, as described above.

[0124] The release of the detachable connection can be a mechanical process in which both the first and second removable sections are simultaneously removed from their protective position. Release can be achieved through various actuating mechanisms, such as levers, buttons, rotary handles, or quick-release fasteners. The release can result in the complete separation of both the first and second removable sections together from the fixed section. The release can be reversible, allowing the first and second removable sections to be returned to their protective positions. Alternatively, the release can enable the coordinated movement of the first and second removable sections as a single unit.

[0125] Rotation around the rotatable connection can be configured as a rotational movement of the second removable section relative to the first removable section. This rotation can occur around various axes, such as a vertical, horizontal, or inclined axis. The rotation can encompass a continuous range of motion or discrete positions. Optionally, the removable section can be held or fixed in these discrete positions by means of magnetic detents and / or mechanical locking points. The rotation can allow for independent positioning of the second removable section while the first removable section remains in its original position.Rotating the face shield allows the second removable section to be positioned outside the patient positioning area, thus enabling its removal from its protective position without requiring complete separation from the first removable section. This rotation can be performed manually by operators or automatically by drive mechanisms. Rotating the face shield allows for precise adjustment of its position to meet varying patient needs.

[0126] Advantageously, one axis of rotation of the rotatable connection is oriented horizontally and parallel to the pivot plane of the swivel arm. In particular, the axis of rotation is arranged outside the pivot plane. Specifically, the second removable section can then be designed to be hinged upwards or downwards relative to the first removable section by means of the rotatable connection. In particular, the rotatable connection can then include a pivot joint. For a more detailed description, please refer to the preceding descriptions.

[0127] The combination of a detachable and a rotating connection offers varying degrees of flexibility for patient positioning. The second removable section can initially be moved out of the way by rotating it around the swivel connection to improve accessibility. If even greater freedom of movement is required, both removable sections can be completely removed by releasing the detachable connection.

[0128] This design offers the technical advantage of allowing the protective unit to be adapted in stages to different examination requirements. The modular construction enables optimized patient positioning while maintaining the protective function, thereby improving both patient safety and examination comfort. Specifically, to position the patient, only the second removable section needs to be rotated or folded out of the way, particularly upwards, and thus removed from the protective position. Since the second removable section remains connected to the first removable section and the fixed section, handling is simple, as no disassembly or subsequent assembly is necessary. Furthermore, there is no need to find a storage place for the second removable section, preventing it from being misplaced or lost.If greater flexibility in patient positioning is required, for example due to the patient's size, the removable section can still be completely detached from the fixed section and thus removed from the protective position.

[0129] In another advantageous embodiment of the mammography system, the detachable connection can comprise a plug connection.

[0130] The detachable connection can be designed as a plug-in connection. The plug-in connection can be a mechanical connecting device that, by inserting a first coupling element into a second coupling element, enables a detachable mechanical connection between the first removable section of the protective unit and the fixed section of the protective unit. The first coupling element is located on the first removable section and the second coupling element on the second removable section, or vice versa. The plug-in connection can be designed such that the connection can be established by a plugging motion and released by an opposing pulling motion.

[0131] The connector can incorporate various technical designs. A connector can be a pin-socket connection, where a cylindrical or conical pin is inserted into a correspondingly shaped socket. Alternatively, the connector can be a bayonet connection, where a plug element can be locked by a twisting motion after insertion. Furthermore, the connector can be a quick-release fastener, actuated by a lever mechanism or a clamping device. Optionally, the connector can include a magnetic connecting element.

[0132] The plug connection can include a locking or securing element that prevents unintentional disconnection. Such a locking element can be designed as a latching mechanism, a screw connection, or a clamping device. The latching mechanism can include a spring-loaded detent that engages in a corresponding recess or groove. The screw connection can include a threaded sleeve that can be turned over a thread on the plug element. The clamping device can include a clamping lever or a clamping screw that secures the plug connection by mechanical pressure.

[0133] The connector can include a guide element that ensures correct alignment of the connecting elements during the insertion process. This guide element can be designed as a guide rib, guide groove, or conical insertion aid.

[0134] The connector can be made from various materials that offer sufficient mechanical strength and wear resistance. Suitable materials include metals such as stainless steel, aluminum, or brass. Alternatively, plastic materials such as polyoxymethylene (POM), polyamide (PA), or polyetheretherketone (PEEK) can be used. The material selection may depend on the mechanical requirements, chemical resistance, and hygienic requirements of the mammography environment.

[0135] The connector can be dimensioned to reliably transmit the mechanical forces that may occur during patient positioning and mammography examinations. The connection can possess sufficient rigidity to ensure stable positioning of the second removable section of the protective unit and the face shield. At the same time, the connector can be designed to allow medical personnel to disconnect it without excessive force.

[0136] The connector can include an ergonomic feature that allows for easy handling by medical personnel. Such a feature could include, for example, a grip area, an alignment mark, or color coding. The connector can be designed so that the correct alignment and positioning of the connecting elements is visually or tactilely recognizable.

[0137] The connector can be designed so that connection and disconnection can be performed by a single operator without the need for additional tools or complex handling steps. The connector can be opened and closed using simple hand movements such as pushing, pulling, or twisting.

[0138] The connector may include a mark or indicator that shows the correct connection status. This may be a visual mark, tactile feedback, or an audible signal to confirm to the operator that the connection has been properly established.

[0139] Advantageously, the design of the detachable connection as a plug-in joint allows for particularly quick and intuitive handling of the protective unit. The plug-in connection enables tool-free assembly and disassembly of the first removable section of the protective unit, thereby increasing efficiency during patient positioning. Furthermore, the plug-in connection ensures reproducible and precise positioning of the first removable section, improving the consistency of the protective function during various examination procedures.

[0140] In a second aspect, the invention relates to a protective unit for use in a mammography system described above.

[0141] The protective unit for use in a mammography system can be designed as a standalone component that can be integrated into various mammography systems. The protective unit can be designed as a modular component that can be retrofitted to an existing mammography system or provided as an integral part of a new mammography system. The protective unit can comprise various embodiments, which are described above.

[0142] The use of the protective unit in a mammography system can refer to the integration and operation of the protective unit within the mammography system.

[0143] Advantageously, the protective unit allows a patient to be protected from a collision with the swivel arm of a mammography system without disturbing or restricting the patient's positioning.

[0144] Exemplary embodiments of the invention are shown in the figures and are described in more detail below. The same reference numerals are used in different figures for identical features.

[0145] They show: Fig. 1 an embodiment of a mammography system; Fig. 2 a first embodiment of a protective unit comprising a fixed section and a removable section connected by a detachable connection; Fig. 3a and Fig. 3b a second embodiment of a protective unit with a removable section which is connected to a fixed section via a sliding connection; Fig. 4 a third embodiment of a protective unit with a removable section which is connected to a fixed section via a rotatable connection; Fig. 5 a fourth embodiment of a protective unit with a removable section which is connected to a fixed section via a rotatable connection; Fig. 6 a fifth embodiment of a protective unit with a removable section which is connected to a fixed section via a rotatable connection; Fig. 7 a sixth embodiment of a protective unit comprising a removable section which is connected to a fixed section via a rotatable connection; Fig. 8a and Fig. 8b a seventh embodiment of a protective unit comprising a removable section which is connected to a fixed section via a rotatable connection; Fig. 9 an eighth embodiment of a protective unit with a removable section which is connected to a fixed section via a rotatable connection; Fig. 10 a ninth embodiment of a protective unit comprising a removable section which is connected to a fixed section via a rotatable connection; Fig. 11 a tenth embodiment of a protective unit with a removable section which is connected to a fixed section via a rotatable connection; Fig. 12 an eleventh embodiment of a protective unit with a removable section which is connected to a fixed section via two connecting pieces; Fig. 13 a twelfth embodiment of a protective unit with a removable section which is connected to a fixed section via a connecting piece; Fig. 14 a thirteenth embodiment of a protective unit comprising a removable section which is connected to a fixed section via a connecting piece; Fig. 15a to Fig. 15c a fourteenth embodiment of a protective unit comprising a first and a second removable section.

[0146] Fig. Figure 1 shows an embodiment of a mammography system 100.

[0147] The mammography system 100 comprises a swivel arm 108, an X-ray source 102, and a protective unit 103. The swivel arm 108 can be configured to swivel the X-ray source 102. The protective unit 103 can be stationary and can be positioned in a protective position to prevent a patient from colliding with the swivel arm 108.

[0148] The mammography system 100 can further comprise a compression unit 101, which has a compression plate 106. For imaging, a patient's breast can be compressed between the compression plate 106 and a cover 105.1 of an X-ray detector 105. The X-ray detector 105 can be positioned opposite the X-ray source 102.

[0149] A standing column 107 can serve as a structural support for the mammography system 100 and can support the swivel arm 108. The swivel arm 108 can support the X-ray source 102 at its upper section and can be designed to rotate or swivel through a defined angular range during tomosynthesis. The protective unit 103 can be arranged on the standing column 107 and can extend forward toward the examination area.

[0150] Optionally, the protective unit 103 can be mounted on the upright column 107 via a height adjustment unit. This height adjustment unit can, in particular, comprise a lifting carriage or a linear axis. The height of the protective unit 103 can be adjusted via the height adjustment unit and thus, for example, adapted to the height of a patient. During a mammogram, and especially during movement of the swivel arm 108, the protective unit 103 remains stationary, as the height adjustment only occurs during preparation for the mammogram, specifically during patient positioning.

[0151] The protective unit 103 can comprise a removable section and a fixed section. The removable section of the protective unit 103 can be removed from the protective position. A face shield 104 can be attached to the protective unit 103 and can be designed to keep the patient's head away from the travel path of the swivel arm 108, particularly during tomosynthesis imaging.

[0152] The mammography system 100 can also include a control system 110, which can be connected to the system components. The control system 110 can include an interface 110.1 for communication with system components, a processing unit 110.2 for data processing and control of operations, and a storage unit 110.3 for storing image data and system parameters. A terminal 113 can be provided for user interaction with the mammography system 100 and can enable an operator to control an imaging procedure and view results.

[0153] The arrangement of the components in the mammography system 100 can allow the X-ray source 102 and the swivel arm 108 to move through an angular range, while the protective unit 103 and the face shield 104 remain stationary and maintain a safe distance between the patient's head and the moving components throughout the entire imaging procedure.

[0154] Fig. Figure 2 shows a first embodiment of a protective unit 203 with a fixed section 203.1 and a removable section 203.2, which are connected via a detachable connection 221.

[0155] The protective unit 203 can be used by the mammography system 100 according to Fig. 1 includes its.

[0156] The protective unit 203 comprises a fixed section 203.1 and a removable section 203.2. The fixed section 203.1 may be designed for structural support and for attachment to the mammography system 100.

[0157] The removable section 203.2 can be designed as a separate component from the fixed section 203.1. The removable section 203.2 can include a face shield 204 at its distal end. The face shield 204 can be designed as a rectangular or square component, which provides a support surface for the patient's head during a mammographic examination.

[0158] A releasable connection 221 can be arranged between the fixed section 203.1 and the removable section 203.2. The releasable connection 221 can include a mechanical fastening element that enables a secure connection during normal operation while also allowing for intentional separation when necessary. The releasable connection 221 can be configured as a plug connection, quick-release fastener, bayonet fitting, or an alternative similar connection mechanism.

[0159] The removable section 203.2 can be arranged in a protective position on the fixed section 203.1 via the detachable connection 221. In the protective position, the removable section 203.2 and the fixed section 203.1 can form a continuous protective unit 203, which holds the patient's head in a safe position relative to the moving components of the mammography system 100, in particular to a swivel arm 108.

[0160] The removable section 203.2 can be removed from its protective position by releasing the releasable connection 221. Removal may be necessary for certain patient positioning procedures or specific examination types, such as MLO or magnification imaging. Releasing the releasable connection 221 can be done manually and allows complete separation of the removable section 203.2 from the fixed section 203.1.

[0161] The modular design of the protective unit 203 offers flexibility in patient positioning and supports various examination protocols. When assembled, the protective unit 203, consisting of the fixed section 203.1 and the removable section 203.2, can form a continuous protective unit 203 that positions the patient's head outside the range of motion of the swivel arm 108.

[0162] Fig. 3a and Fig. Figure 3b shows a second embodiment of a protective unit 303 with a removable section 303.2, which is connected to a fixed section 303.1 via a sliding connection 322.

[0163] The protection unit 303 can be used by the mammography system 100 according to Fig. 1 includes its.

[0164] The protective unit 303 comprises a fixed section 303.1 and a removable section 303.2. A face shield 304 may be enclosed by the removable section 303.2. The fixed section 303.1 may be arranged on a standing column 107 of the mammography system 100.

[0165] The removable section 303.2 can be arranged on the fixed section 303.1 of the protective unit 303 via a sliding connection 322. The sliding connection 322 allows the removable section 303.2 to be moved relative to the fixed section 303.1 along a defined path. The removable section 303.2 of the protective unit 303 can be removed from the protective position along the sliding connection 322.

[0166] Fig. Figure 3a shows a front perspective view of the protective unit 303 in a position different from the protective position. The sliding connection 322 is designed so that the removable section 303.2 can be moved along a defined path relative to the fixed section 303.1.

[0167] Fig. Figure 3b shows a side perspective view of the protective unit 303 and illustrates the spatial relationship between the components. The sliding connection 322 can be configured such that the removable section 303.2 of the protective unit 303 is slidable parallel to a pivot plane of the pivot arm 308. This configuration allows the removable section 303.2 to be retracted or extended (or, in other words, laterally displaced), thereby enabling adjustment of the position of the removable section 303.2 to meet various patient positioning requirements or to provide clearance for specific imaging procedures such as MLO or magnification imaging.

[0168] In particular, in this embodiment, the path of movement defined by the sliding connection 322 is designed as part of a circular path. This prevents a collision between the removable section 303.2 and the pivot arm 308 during a pivoting movement in any position.

[0169] Fig. Figure 4 shows a third embodiment of a protective unit 403 with a removable section 403.2, which is connected to a fixed section 403.1 via a rotatable connection 423.

[0170] The protection unit 403 can be used by the mammography system 100 according to Fig. 1 includes its.

[0171] The protective unit 403 can comprise a fixed section 403.1 and a removable section 403.2. The fixed section 403.1 can be arranged on the structure of the mammography system, in particular on the upright column 107, and provide a stable attachment point. The removable section 403.2 can extend from the fixed section 403.1 and comprise a face shield 404.

[0172] The removable section 403.2 can be arranged on the fixed section 403.1 of the protective unit 403 via a rotatable connection 423. The rotatable connection 423 can be designed such that the removable section 403.2 is pivotable or rotatable relative to the fixed section 403.1. In this way, the removable section 403.2 can be removed from its protective position and returned to it. The rotatable connection 423 can be positioned at the connection point between the fixed section 403.1 and the removable section 403.2.

[0173] The removable section 403.2 of the protective unit 403 can be removed from the protective position by rotating it about the rotatable connection 423. The rotatable connection 423 can include a horizontal axis of rotation aligned parallel to a pivot plane of the pivot arm 108, enabling the removable section 403.2 to rotate upwards and downwards. In particular, the axis of rotation can be located outside the pivot plane. The rotatable connection 423 can be located centrally within the protective unit 403, thus enabling balanced movement of the removable section 403.2 and the face shield 404.

[0174] The face shield 404 can be encompassed by the distal end of the removable section 403.2. The face shield 404 can be configured to provide protection for a patient's head during mammography imaging, particularly during tomosynthesis, by keeping the head away from moving components, especially the swivel arm 108. The configuration can allow the removable section 403.2 to be moved out of the way for patient positioning when necessary, particularly during MLO and / or magnification imaging.

The rotatable connection 523 is designed such that the removable section 503.2 can rotate relative to the fixed section 503.1. By rotating the removable section 503.2 about the rotatable connection 523, the removable section 503.2 can be moved out of or back into the protective position. This rotatability allows the removable section 503.2 to be moved out of the way during patient positioning while maintaining its attachment to the fixed section 503.1.

[0179] The protective unit 503 can be positioned to protect the patient's head and face from the swivel arm 508 during an imaging procedure, especially during tomosynthesis.

[0180] The rotatable connection 523 can include a horizontal axis of rotation aligned parallel to a pivot plane of the swivel arm 508. In particular, the axis of rotation can be located outside the pivot plane. The removable section 503.2 can be rotated or pivoted upwards or downwards about this axis of rotation. This arrangement can allow the removable section 503.2 to be folded upwards to improve patient access and comfort during various examination procedures, such as MLO or magnification radiography, without having to completely remove the removable section 503.2 from the system.

[0181] Optionally, the rotatable connection 523 can include a sliding unit on which the removable section 503.2 can be extended and retracted relative to the fixed section 503.1. In particular, the height of the face shield 604 can thus be adjusted to the height of a patient.
