Summary of the Invention

[0007] The present invention is a medical image diagnostic system having a computed tomography gantry, a carriage, a rail system, and a support profile, The computed tomography gantry is mounted movably by a carriage and rail system, so that parallel movement of the computed tomography gantry relative to the base plane along the rail system is possible. The support profile is received by engaging with a recess formed in the base surface. The support profile has rail slots for receiving the rails of the rail system by fitting, The rails of the rail system are received by engaging with the rail slots, and therefore the rails of the rail system do not protrude vertically from the base surface. Regarding medical imaging diagnostic systems.

[0008] Therefore, the rails of the rail system do not get in the way when stepped on and do not require covers for liquids and / or dust, which often need to be maintained due to mechanical loads. Furthermore, the open design of the rails makes cleaning easier.

[0009] Optionally, it can be assumed that any tangent planes parallel to the base surface and in contact with the rails of the rail system do not extend above the base surface.

[0010] Optionally, the base surface has a first base surface region and a second base surface region. The first base surface region and the second base surface region are on the same plane as each other. The recess is located between the first base surface region and the second base surface region. The rails of the rail system are received by engaging with the rail slots, so that the rails of the rail system do not protrude from the first base surface region, and the rails of the rail system do not protrude from the second base surface region. This is a possibility.

[0011] In particular, the recess may be located between the first base surface region and the second base surface region in a lateral direction perpendicular to the longitudinal direction of the rails of the rail system and / or parallel to the base surface. For example, the first base surface region and the second base surface region are separable from each other by the recess.

[0012] In particular, it may be assumed that a tangent plane parallel to the base surface, touching the highest point of the rails of the rail system, does not extend above the first base surface region and / or above the second base surface region. In particular, it may be assumed that a tangent plane parallel to the base surface, touching the highest point of the rails of the rail system, lies coplanar with the first base surface region and / or the second base surface region.

[0013] Optionally, it can be assumed that the support profile has a connecting surface and is received by engaging with a recess, so that the connecting surface is joined to the base surface without any step, particularly on the same plane, and especially as an extension of the base surface.

[0014] The extension of the base surface may be particularly continuous. In particular, it may be assumed that a tangent plane parallel to the base surface, which is in contact with the highest point of the rails of the rail system, lies coplanar with the base surface and / or the connecting surface.

[0015] Optionally, the connecting surface has a first connecting surface region and a second connecting surface region. The rails of the rail system are located between the first connection surface area and the second connection surface area. The support profile is received by engaging with the recess, so that the first connection surface region is joined to the first base surface region without step, particularly on the same plane, particularly as an extension of the first base surface region, and the second connection surface region is joined to the second base surface region without step, particularly on the same plane, particularly as an extension of the second base surface region. This is a possibility.

[0016] The extension of the first base surface region can be particularly continuous. The extension of the second base surface region can be particularly continuous. In particular, it can be assumed that the rail of the rail system is located between the first connection surface region and the second connection surface region in a transverse direction perpendicular to the longitudinal direction of the rail of the rail system and / or parallel to the base surface. The first connection surface region and the second connection surface region can, for example, be in the same plane as each other.

[0017] Optionally, the base surface extends substantially horizontally, and the rail of the rail system is received by engaging with the rail slot, so that the rail of the rail system does not protrude from the base surface in the vertical direction can be assumed.

[0018] In particular, it can be assumed that a tangent plane parallel to the base surface is horizontal with respect to the rail of the rail system and / or the connection surface extends substantially horizontally. In particular, it can be assumed that the longitudinal direction of the rail of the rail system is horizontal and / or the transverse direction perpendicular to the longitudinal direction of the rail of the rail system and / or parallel to the base surface is horizontal. In particular, it can be assumed that the highest point of the rail of the rail system is not arranged higher than the base surface in the vertical direction.

[0019] Optionally, the rail of the rail system is the first rail of the rail system and is arranged parallel to the second rail of the rail system, the base surface is substantially parallel to the rail plane, and the rail plane extends through the first rail of the rail system and the second rail of the rail system, can be assumed.

[0020] Optionally, it can be assumed that the rail of the rail system has a round profile, particularly a circular profile, in a cross-sectional plane perpendicular to the longitudinal direction of the rail of the rail system.

[0021] In particular, it can be assumed that the rail of the rail system has a convex profile, in particular a circular profile, in a cross-sectional plane perpendicular to the longitudinal direction of the rail of the rail system.

[0022] Optionally, it can be assumed that the rail of the rail system has a rounded rectangular profile in a cross-sectional plane perpendicular to the longitudinal direction of the rail of the rail system.

[0023] Optionally, the support profile has profile-side connection elements in the region of the rail slot, the rail of the rail system has rail-side connection elements designed to correspond to the profile-side connection elements, and the rail of the rail system is fixed against rotation about the longitudinal axis of the rail of the rail system relative to the support profile by the engagement of the profile-side connection elements and the rail-side connection elements. This can be assumed.

[0024] Furthermore, the present invention is a medical imaging diagnostic system having a computed tomography gantry, a carriage, a rail system, and a support profile, where the computed tomography gantry is movably attached by the carriage and the rail system, so that a translational movement of the computed tomography gantry relative to the base surface can be performed along the rail system, the support profile is received by engaging a recess formed in the base surface, the support profile has a rail slot for receiving the rail of the rail system by fitting the rail, the support profile has profile-side connection elements in the region of the rail slot, the rail of the rail system has rail-side connection elements designed to correspond to the profile-side connection elements, The rails of the rail system are fixed to the support profile by the engagement of the profile-side connecting elements and the rail-side connecting elements, preventing rotation of the rails of the rail system around the longitudinal axis of the rails. Regarding medical imaging diagnostic systems.

[0025] Optionally, the profile-side connecting element protrudes in a pin shape toward the rail of the rail system in a direction perpendicular to the longitudinal axis of the rail of the rail system. The rail-side connecting element has a cavity for receiving the profile-side connecting element. This is a possibility.

[0026] Optionally, the rail-side connecting element protrudes in a pin-like manner, perpendicular to the longitudinal axis of the rail in the rail system, and away from the rail in the rail system. The profile-side connecting element has a space for receiving the rail-side connecting element. This is a possibility.

[0027] Optionally, the void may be assumed to be a perforation, particularly in the form of a circular hole.

[0028] Optionally, the void may be assumed to be an elongated hole and / or to extend elongatedly parallel to the longitudinal axis of the rails of the rail system.

[0029] In particular, it may be conceivable that the rails of the rail system can be received by engaging them with the rail slots, specifically by lowering the rails of the rail system relative to the support profile in a vertical downward direction perpendicular to the longitudinal axis of the rails of the rail system. For this purpose, the support profile may be designed, for example, to have no undercuts, and / or to be designed in multiple parts such that undercuts are formed only after the rails of the rail system are inserted into the rail slots and subsequently joined to the support profile.

[0030] Optionally, the carriage and rail system are configured to transmit the driving force for the parallel movement of the computed tomography gantry, particularly by force coupling from the carriage to the rail system through friction.

[0031] In particular, it may be assumed that the rail system is stationary with respect to the base surface and / or strongly anchored to the base surface. In particular, it may be assumed that the object under inspection is stationary with respect to the rail system and / or the base surface. The rail system can, in particular, form a linear guide for the carriage.

[0032] For example, a medical imaging diagnostic system may have an examination table for positioning the object to be examined. The examination table may be stationary in particular with respect to a rail system and / or a base surface, and / or may be strongly anchored in respect to a rail system and / or a base surface. The object to be examined may be, for example, a person being examined, in particular a patient, and / or may be placed on the examination table, in particular, stationary in relation to the examination table.

[0033] Translation can be performed in particular with respect to the rail system, the base surface, the inspection table, and / or the object being inspected. Translation can be substantially horizontal in particular. The base surface can be substantially horizontal in particular. The base surface can be the floor of the inspection room and / or made of concrete.

[0034] A computed tomography gantry may, for example, have a support frame and a rotor rotatably mounted to the support frame, with a radiation source and radiation detector positioned on the rotor. Optionally, the computed tomography gantry may have a tiltable frame tiltable to the support frame, with the rotor positioned on the tiltable frame. The radiation source and radiation detector can interact to record a projection dataset of the object being examined. The computed tomography gantry may, for example, have an aperture. In particular, the rail system, examination table, and aperture may be positioned relative to each other so that the examination table is introduced into the aperture by translation of the computed tomography gantry, and especially so that the object being examined, placed on the examination table, is introduced into the aperture together with the object being examined.

[0035] In one embodiment, a set of wheel-rail rolling contacts is provided between the carriage and the rail system, and the carriage and rail system are configured to transmit the driving force for the parallel movement of the computed tomography gantry from the carriage to the rail system by force connection through the set of wheel-rail rolling contacts.

[0036] In one embodiment, a set of wheel-rail rolling contacts supports the total weight force of the carriage and computed tomography gantry, and each wheel-rail rolling contact included in the set of wheel-rail rolling contacts, which supports at least a portion of the total weight force of the carriage and computed tomography gantry, is assumed to transmit at least a portion of the driving force for the parallel movement of the computed tomography gantry by force connection, particularly by friction.

[0037] In particular, it may be assumed that at least a portion of the total gravitational force of the carriage and computed tomography gantry is not insignificant, but rather greater than, for example, one-tenth of the total gravitational force of the carriage and computed tomography gantry. In particular, it may be assumed that at least a portion of the driving force for the translation of the computed tomography gantry is not insignificant, but rather greater than, for example, one-tenth of the driving force for the translation of the computed tomography gantry.

[0038] In particular, in the case of medical imaging systems, it may be possible to exclude wheel-rail rolling contacts that support a portion of the total weight force of the carriage and computed tomography gantry but do not transmit any driving force for the parallel movement of the computed tomography gantry.

[0039] The frictional force available for driving depends on the friction value and the normal force applied to the friction wheels. In particular, when the wheels are directly driven and friction at the wheel-rail rolling contact is utilized, the total gravitational force of the carriage and computed tomography gantry can be used as the normal force. In the case of friction wheels, only a portion of the gravitational force is available as the normal force because the gravitational force distribution between the rail wheels and the friction wheels is taken into account.

[0040] In one embodiment, it is assumed that the rail system has a set of rails, and the carriage has a set of wheels, and the set of wheels is arranged to roll on the set of rails. The set of rails may, for example, have the rails of the rail system. The set of rails may, for example, have a first rail of the rail system and / or a second rail of the rail system.

[0041] In particular, it may be assumed that a set of rails and a set of wheels form a set of wheel-rail rolling contacts. Specifically, it may be assumed that each rail in the set of rails is a round rail, and / or that each wheel in the set of wheels is a concave roller and / or designed to roll on a round rail. For example, the rails and / or wheels may be made of steel.

[0042] The round rail can be integrated into the floor, in particular, without a cover and without drive elements, allowing patient beds and instrument tables to travel above it. The driving force for the parallel movement of the computed tomography gantry can be transmitted from the carriage to the rail system, for example, based on force coupling, particularly friction coupling, between the wheels of a set of wheels and the rails of a set of rails.

[0043] In one embodiment, the carriage is assumed to have a wheel direct drive unit for each wheel in a set of wheels, which interacts with the wheel and contributes proportionally to the driving force for the parallel movement of the computed tomography gantry.

[0044] In particular, it may be assumed that for each wheel in a set of wheels, a wheel direct drive unit interacting with that wheel directly drives the wheel, thereby contributing proportionally to the driving force for the parallel movement of the computed tomography gantry. In particular, it may be assumed that the driving force for the parallel movement of the computed tomography gantry is generated together by the wheel direct drive units of the set of wheels. The wheel direct drive unit may have, for example, an electric motor, in particular an electric wheel hub motor (Elektro-Radnabenmotor).

[0045] In one embodiment, the medical imaging diagnostic system further includes a position measurement system, which is configured to generate position information, and it is assumed that the position information relates to the position of a computed tomography gantry along a rail system.

[0046] The position of the computed tomography gantry along the rail system can be defined with respect to a reference point that is stationary with respect to the base plane and / or the rail system, in particular, with respect to a reference point that is stationary with respect to the base plane and / or the rail system during translation of the computed tomography gantry with respect to the rail system. In particular, it can be assumed that the position of the computed tomography gantry along the rail system is measured continuously, in particular at a sufficiently high scanning speed, during translation of the computed tomography gantry, in particular that the position information of each projection dataset recorded by the computed tomography gantry under examination during translation of the computed tomography gantry is measured to include the position of the computed tomography gantry on which this projection dataset was recorded.

[0047] In one embodiment, it is assumed that the position measurement system is configured to generate position information based on the measurement of the position of the computed tomography gantry along the rail system, particularly based on non-contact measurement.

[0048] Non-contact measurement can be performed, for example, optically, magnetically, magnetostrictively, inductively, and / or capacitively, and / or based on run-time measurement. The combination of force transmission by force fastening between the wheel and rail and non-contact position measurement enables accurate positioning and detection of the carriage with minimal engagement surfaces, potentially eliminating the need for engagement in both driving and position measurement. This improves cleanability and reduces wear.

[0049] The position of the computed tomography gantry along the rail system can be measured either absolutely, for example, using an absolute encoder, or incrementally, for example, using an incremental encoder.

[0050] In one embodiment, the position measurement system includes a measurement track (Masspur) and position sensors, where the measurement track is stationary relative to the rail system and extends along the rail system, and the position sensors are connected to a carriage, so that the position sensors follow the translational movement of the computed tomography gantry and interact with the measurement track during the translational movement of the computed tomography gantry to perform, in particular, measurement of the position of the computed tomography gantry along the rail system, especially non-contact measurement.

[0051] The measurement track may be, for example, a code track. The position sensor may be specifically adjusted to scan the code track. The measurement track may be, for example, a magnetic band. The magnetic band may be specifically magnetized at regular intervals. The measurement track may be, for example, a measurement band, particularly a stainless steel measurement band, and / or may be strongly anchored to a base surface.

[0052] In one embodiment, it is assumed that the medical imaging diagnostic system further has a support profile, and the support profile has a measurement track slot for receiving a measurement track, in particular by engagement, and the measurement track is received in the measurement track slot, in particular by engagement, and the support profile has a rail slot for receiving a rail of a rail system by fitting, and the rail of the rail system is received by engaging in the rail slot.

[0053] In particular, it may be assumed that the support profile extends along the rail system and / or that the support profile is strongly anchored to the base surface. In particular, the measurement track slots and rail slots may be arranged substantially parallel to each other. In particular, the measurement track may be bonded to the support profile.

[0054] In one embodiment, it is assumed that the medical imaging diagnostic system further comprises a data processing unit, which is configured to calculate a drive signal based on positional information, and that the carriage comprises a drive unit, which is configured to generate a driving force for the parallel movement of the computed tomography gantry in response to the drive signal.

[0055] In particular, it is conceivable that the direct drive units of the wheels of a set of wheels may come together to form a drive system.

[0056] Furthermore, here is a medical system having a support structure, a carriage, a rail system, and a support profile, The support structure is movably mounted by a carriage and rail system, so that parallel movement of the support structure relative to the base surface along the rail system is possible. The support profile is received by engaging with a recess formed in the base surface. The support profile has rail slots for receiving the rails of the rail system by fitting, The rails of the rail system are received by engaging with the rail slots, and therefore the rails of the rail system do not protrude vertically from the base surface. The healthcare system is disclosed.

[0057] Furthermore, here is a medical system having a support structure, a carriage, a rail system, and a support profile, The support structure is movably mounted by a carriage and rail system, so that parallel movement of the support structure relative to the base surface along the rail system is possible. The support profile is received by engaging with a recess formed in the base surface. The support profile has rail slots for receiving the rails of the rail system by fitting, The support profile has a profile-side connecting element in the area of ​​the rail slot. The rails of the rail system have rail-side connecting elements designed to correspond to profile-side connecting elements. The rails of the rail system are fixed to the support profile by the engagement of the profile-side connecting elements and the rail-side connecting elements, preventing rotation of the rails of the rail system around the longitudinal axis of the rails. The healthcare system is disclosed.

[0058] It is assumed that, optionally, the carriage and rail system are configured to transmit the driving force for the parallel movement of the support structure from the carriage to the rail system by force fastening.

[0059] A medical system having a support structure may be designed similarly to, for example, one of the embodiments described for a medical imaging system having a computed tomography gantry. The medical system may be, for example, an X-ray imaging system having a C-arm in particular as a support structure, a magnetic resonance imaging system having a support structure in particular for holding a body coil, a radiotherapy device having a support structure in particular for holding a radiation source, or a patient placement device having a patient bed in particular as a support structure.

[0060] Within the scope of the present invention, further embodiments of the invention can be formed by combining features described in relation to different embodiments and / or different claim categories (such as methods, uses, apparatus, systems, and arrangements) of the invention. For example, a claim relating to an apparatus can be further expanded by features described or claimed in relation to a method, and vice versa. Here, the functional features of a method can be performed by specific components provided in correspondence. The use of the indefinite article "ein" or "eine" does not preclude the existence of multiple related features.

[0061] The features of the present invention will be described below with reference to the attached drawings, based on examples. The representations in the drawings are schematic, greatly simplified, and not necessarily to scale. [Brief explanation of the drawing]

[0065] A set of wheel-rail rolling contacts RL is provided between the carriage F and the rail system L, and the carriage F and the rail system L are adjusted so that the driving force for the parallel movement of the computed tomography gantry 20 is transmitted from the carriage F to the rail system L by force connection via the set of wheel-rail rolling contacts RL. The set of wheel-rail rolling contacts RL supports the total weight of the carriage F and the computed tomography gantry 20, and each wheel-rail rolling contact included in the set of wheel-rail rolling contacts RL, which supports at least a portion of the total weight of the carriage F and the computed tomography gantry 20, transmits at least a portion of the driving force for the parallel movement of the computed tomography gantry 20 by force connection. The rail system L has a set of rails, and the carriage F has a set of wheels R, which are arranged to roll on the set of rails. The carriage F has a wheel direct drive unit for each wheel of the set of wheels R, which interacts with the wheel and contributes proportionally to the driving force for the parallel movement of the computed tomography gantry 20.

[0066] The medical imaging diagnostic system 1 further includes a position measurement system M, which is tuned to generate position information S2, the position information relating to the position of the computed tomography gantry 20 along the rail system L. The position measurement system M is tuned to generate position information S2 based on non-contact measurement of the position of the computed tomography gantry 20 along the rail system L. The position measurement system M includes a measurement track B and a position sensor N, the measurement track B is stationary with respect to the rail system L and extends along the rail system L, and the position sensor N is connected to the carriage F, so that the position sensor N follows the translation of the computed tomography gantry 20 and interacts with the measurement track B during the translation of the computed tomography gantry 20. For example, other rail areas of the rail system L (the left portion in Figure 3) may also be provided with corresponding position measurement systems, in particular measuring tracks and position sensors.

[0067] The medical imaging diagnostic system 1 further includes a data processing unit D, which is tuned to calculate a drive signal based on position information, and the carriage F has a drive unit FR, which is tuned to generate a drive force for the parallel movement of the computed tomography gantry 20 in response to the drive signal.

[0068] The computed tomography gantry 20 has an opening 9. By translating the computed tomography gantry 20, the examination table can be introduced into the opening 9, in particular, together with the object to be examined which is placed on the examination table.

[0069] The example shown is a medical imaging diagnostic system 1 having a computed tomography gantry 20, a carriage F, a rail system L, and a support profile P. The computed tomography gantry 20 is movably mounted by a carriage F and a rail system L, so that parallel movement of the computed tomography gantry 20 relative to the base plane U along the rail system L can be performed. The support profile P is received by engaging with a recess UP formed in the base surface U. The support profile P has rail slots PS for receiving the rail S of the rail system L by fitting, The rail S of the rail system L is received by engaging with the rail slot PS, and therefore the rail S of the rail system L does not protrude from the base surface U in the vertical direction. Regarding medical imaging diagnostic system 1.

[0070] In the example shown, it is assumed that any tangent planes SE parallel to the base plane U and tangent to the rail S of the rail system L do not extend above the base plane U.

[0071] In the example shown, the base surface U has a first base surface region U1 and a second base surface region U2. The first base surface region U1 and the second base surface region U2 are on the same plane as each other. The recess UP is positioned between the first base surface region U1 and the second base surface region U2. The rail S of the rail system L is received by engaging with the rail slot PS, and therefore the rail S of the rail system L does not protrude from the first base surface region U1, and the rail S of the rail system L does not protrude from the second base surface region U2. This is expected to happen.

[0072] In the example shown, the support profile P has a connecting surface PE, The support profile P is received by engaging with the recess UP, and so the connecting surface PE is joined to the base surface U without any step, particularly on the same plane, and especially as an extension of the base surface U. This is expected to happen.

[0073] In the example shown, the connecting surface PE has a first connecting surface region PE1 and a second connecting surface region PE2. The rail S of the rail system L is located between the first connection surface area PE1 and the second connection surface area PE2. The support profile P is received by engaging with the recess UP, so that the first connection surface region PE1 is joined to the first base surface region U1 without any step, particularly on the same plane, and particularly as an extension of the first base surface region U1, and the second connection surface region PE2 is joined to the second base surface region U2 without any step, particularly on the same plane, and particularly as an extension of the second base surface region U2. This is expected to happen.

[0074] In the example shown, the base plane U extends substantially horizontally. The rail S of the rail system L is received by engagement with the rail slot PS, and therefore the rail S of the rail system L does not protrude from the base surface U in the vertical direction. This is expected to happen.

[0075] In the example shown, rail S of rail system L is the first rail SA of rail system L, and is positioned parallel to the second rail SB of rail system L.

The rail S of the rail system L is fixed to rotation about the longitudinal axis of the rail S of the rail system L relative to the support profile P by the engagement of the profile-side connecting element T and the rail-side connecting element ST. This is expected to happen.

[0078] In the example shown, the profile-side connecting element T protrudes in a pin shape toward the rail S of the rail system L, perpendicular to the longitudinal axis of the rail S of the rail system L. The rail-side connecting element ST has a cavity for receiving the profile-side connecting element T. This is expected to happen.

[0079] In the example shown, it is assumed that the void is in the form of a round hole or an elongated hole and / or that the void extends elongatedly with respect to the longitudinal axis of the rail S of the rail system L.
