Description

Technical Field

[0001] This invention relates to a method for detecting computed tomography (CT) imaging data. This invention also relates to a CT imaging device. Background Technology

[0002] Computed tomography (CT) equipment typically comprises several components, particularly an X-ray source, an X-ray detector, and a rotating transport unit, for example, in the form of a slip ring. These components are arranged on a basic annular gantry of the CT equipment, which has openings. The objects to be examined using the CT equipment can be placed within these openings.

[0003] In principle, it is advantageous to have the largest possible diameter of the opening so that large examination objects can be placed within it, and to keep the external dimensions of the rack as small as possible so as to minimize the space requirements for the computed tomography equipment. Summary of the Invention

[0004] The objective of this invention is to provide an option for the routine examination of computed tomography (CT) imaging data. Each subject matter of the independent claims addresses this objective. Further advantageous aspects of the invention are considered in the dependent claims.

[0005] This invention relates to a method for detecting computed tomography (CT) imaging data.

[0006] -Simultaneously, the rotating frame rotates relative to the flipping frame, and the flipping frame flips relative to the supporting frame. The rotating frame rotates around the rotation axis, and the flipping frame flips around the flipping axis.

[0007] -In this configuration, the X-ray source and X-ray detector are connected to and fixed relative to the rotating frame, allowing for simultaneous rotation of the rotating frame and flipping of the flipping frame.

[0008] - In this process, computed tomography imaging data is detected using an X-ray source and an X-ray detector, while simultaneously performing rotational motion of the rotating frame and flipping motion of the flipping frame.

[0009] For example, it can be proposed that the rotating frame is connected to the tilting frame by means of a rotating support, so that the rotating frame follows the tilting movement of the tilting frame relative to the carrying frame, and in particular, the rotational movement of the rotating frame relative to the tilting frame and the tilting movement of the tilting frame relative to the carrying frame are performed simultaneously. The tilting frame can be connected to the carrying frame by means of a tilting support, for example.

[0010] In particular, the X-ray source and X-ray detector can follow the rotational movement of the rotating frame, allowing the X-ray source and X-ray detector to rotate around the object being examined. The object being examined can be, for example, a part of the human body, especially the head. Computed tomography imaging data can especially relate to the object being examined.

[0011] In particular, computed tomography imaging data can be detected by means of an X-ray source and an X-ray detector, thereby enabling X-rays to be sent by means of the X-ray source, for example, toward the object being examined, and to be received by means of the X-ray detector, for example, after interacting with the object being examined.

[0012] One embodiment proposes that the rotation axis is substantially perpendicular to, and in particular perpendicular to, the flipping axis. Specifically, it can be proposed that the rotating frame is rotatably supported relative to the flipping frame about the rotation axis by means of a rotation support, and / or the flipping frame is flipped relative to the load-bearing frame about the flipping axis by means of a flipping support. The flipping axis can be, for example, substantially horizontal, and in particular, horizontal.

[0013] One embodiment proposes that the flipping movement of the flipping frame includes a first flip angle change of the flipping angle of the flipping frame relative to the supporting frame. The first flip angle change may, for example, be at least 1°. The flipping movement of the flipping frame can be adapted in particular to the anatomical structure of the object being examined. The first flip angle change may, for example, be at least 5°, especially at least 10°, especially at least 15°, especially at least 20°.

[0014] One embodiment proposes that the flipping movement of the flipping frame includes a second flip angle change of the flipping angle of the flipping frame relative to the supporting frame, the second flip angle change occurring temporally after the first flip angle change and pointing in the opposite direction to the first flip angle change of the flipping frame. The second flip angle change may, for example, be at least 1° and / or coincide with the first flip angle change in absolute value.

[0015] One embodiment proposes that the rotational motion of the rotating frame includes a rotation angle change of the rotation angle of the rotating frame relative to the flipping frame, wherein the rotation angle change starts simultaneously with a first flipping angle change and ends simultaneously with a second flipping angle change.

[0016] In particular, it can be proposed that the time interval between the start of the first flip angle change and the end of the second flip angle change is equal to the duration of the rotation angle change. The rotation angle change can be at least 180°, for example, especially equal to the sum of 180° and the fan-shaped beam angle of the X-rays, for example, equal to 190° or 200°. The rotation angle change can be, in particular, one of a plurality of successive rotation angle changes, which together form the rotational motion of the rotating frame. For example, the rotation angle change can be less than 180°, especially less than 90°, especially less than 45°.

[0017] One implementation proposes that the flipping motion of the flipping frame is periodic, wherein the frequency of the flipping motion of the flipping frame is greater than the rotational speed of the rotational motion of the rotating frame.

[0018] The rotational speed of the rotating frame can be, for example, at least one revolution per second. The frequency of the flipping motion of the flipping frame can be, for example, greater than two, four, or ten times the rotational speed of the rotating frame. The periodic flipping motion can, for example, include a first flip angle change and / or a second flip angle change. In particular, the periodic flipping motion can include at least one repetition of the first flip angle change and / or at least one repetition of the second flip angle change.

[0019] One embodiment proposes that the X-ray detector is a planar image detector. Compared to using a conventional computed tomography (CT) X-ray detector, using a planar image detector can reduce the number of components, cost, weight, and space requirements of the computed tomography equipment. The planar image detector can, for example, be a direct conversion. This planar image detector can, for example, have an effective area of ​​30 cm by 40 cm. In particular, the X-ray source can be configured to emit X-rays that form a cone beam corresponding to the planar image detector.

[0020] One implementation proposes that computed tomography imaging data includes multiple time-sequentially detected projection data sets, wherein flip angle data is provided, wherein each of the multiple time-sequentially detected projection data sets is assigned a corresponding flip angle of the flip frame relative to the support frame based on the flip angle data, wherein the computed tomography image is calculated based on the multiple time-sequentially detected projection data sets and the flip angle data.

[0021] Specifically, it can be proposed to detect the actual value of the flip angle data using a flip angle sensor, while detecting computed tomography imaging data using an X-ray source and X-ray detector, and / or calculating the rated value of the flip angle data based on control data and corresponding calibration data of the flip actuator. The flip angle data can be provided, in particular, based on the actual value of the flip angle data and / or based on the rated value of the flip angle data.

[0022] Computed tomography images can be, for example, two-dimensional or three-dimensional, and / or can image at least one region of the object being examined.

[0023] Projected data sets are detected sequentially in time during the rotational motion of the rotating frame and the flipping motion of the flipping frame. By using projected data sets, artifacts in computed tomography images can be avoided, which would occur if the rotational motion of the rotating frame were performed at a constant flip angle. These include, for example, cone-beam artifacts. These can particularly affect areas within the base of the skull. By avoiding cone-beam artifacts, the accuracy of planar image detectors, for example, can be improved for stroke diagnosis.

[0024] One implementation proposes simultaneously performing the rotational movement of the rotating frame, the flipping movement of the flipping frame, and the translational movement of the object to be examined relative to the supporting frame, wherein the translational movement of the object to be examined is performed along a translation axis, wherein computed tomography imaging data is detected from the object to be examined using an X-ray source and an X-ray detector, during which the rotational movement of the rotating frame, the flipping movement of the flipping frame, and the translational movement of the object to be examined are performed simultaneously.

[0025] Translational movement of the object to be examined relative to the supporting frame can be performed, for example, by performing translational movement of the bed support plate relative to the supporting frame and / or relative to the base surface, wherein the object to be examined lies on the support plate and is stationary relative to the support plate.

[0026] One implementation proposes simultaneously performing the rotational movement of the rotating frame, the flipping movement of the flipping frame, and the translational movement of the support frame relative to the object being examined, wherein the translational movement of the support frame is performed along a translation axis, wherein computed tomography imaging data is detected from the object being examined using an X-ray source and an X-ray detector, during which the rotational movement of the rotating frame, the flipping movement of the flipping frame, and the translational movement of the support frame are performed simultaneously.

[0027] One embodiment proposes that the translational movement of the supporting frame is driven relative to a base surface by a translation actuator, wherein the object to be inspected is stationary relative to the base surface. The base surface may be, for example, the ground, particularly the floor of the inspection room, and / or have a base plate and / or a substrate. In particular, it may be proposed that the surface of the base surface is substantially horizontal, especially level.

[0028] Translational movement of the support frame relative to the object being inspected can be achieved, for example, by translating the sliding frame relative to the base surface, wherein the support frame is arranged on the sliding frame and the support frame is stationary relative to the sliding frame. The sliding frame can be movably supported relative to the base surface, for example, by means of a set of wheels, especially wheels that can roll on the base surface, and / or by means of a track system.

[0029] Translational movement of the sliding frame relative to the base surface can be achieved, for example, by implementing translational movement of the sliding frame relative to the traveling mechanism, wherein the sliding frame is movably supported on the traveling mechanism and the traveling mechanism is stationary relative to the base surface, while the translational movement of the sliding frame is implemented relative to the base surface. The traveling mechanism can be particularly designed for longer transport movements of the support frame, such as for moving back and forth between different inspection chambers. Conversely, translational movement of the sliding frame relative to the traveling mechanism can be particularly designed for precise scanning movements of the support frame relative to the object being inspected.

[0030] One implementation proposes that the translation axis is substantially perpendicular, and in particular perpendicular, to the flip axis. The translation axis may, for example, be substantially horizontal, and in particular, horizontal.

[0031] The present invention also relates to a computed tomography apparatus configured to implement a method for detecting computed tomography imaging data according to the present invention, wherein the computed tomography apparatus has a rotating frame, a flipping frame, a support frame, an X-ray source, and an X-ray detector. The X-ray detector may, for example, be a planar image detector.

[0032] Furthermore, the computed tomography (CT) apparatus may particularly include: a rotation support for the rotating frame relative to the flipping frame; a rotation driver for driving the rotational movement of the rotating frame; a flipping support for the flipping frame relative to the supporting frame; and / or a flipping driver for driving the flipping movement of the flipping frame. Furthermore, the CT apparatus may particularly include a translation driver for driving the translational movement of the supporting frame relative to the object being examined and / or relative to the base plane. Furthermore, the CT apparatus may particularly include a translation driver for driving the translational movement of the object being examined relative to the supporting frame and / or relative to the base plane.

[0033] Furthermore, the computed tomography (CT) apparatus may particularly include a rotational transfer unit for rotating and transferring electrical energy from a tilting frame to a rotating frame. Additionally, the CT apparatus may particularly include a rotational transfer unit for rotating and transferring computed tomography imaging data from the rotating frame to the tilting frame, and / or for bidirectional rotational transfer of control data and / or operational data between the tilting frame and the rotating frame. Furthermore, the CT apparatus may particularly include a tilt angle sensor.

[0034] Computed tomography (CT) equipment can be, in particular, medical CT equipment. CT equipment can be specifically configured as head CT equipment and / or mobile CT equipment. CT equipment can be specifically installed in intensification stations, operating rooms and intervention rooms, and / or mobile stroke units.

[0035] One embodiment proposes that the computed tomography (CT) apparatus has a rack, the rack having a first rack portion and a second rack portion.

[0036] The first frame section includes a rotating frame, a flipping frame, a load-bearing frame, an X-ray source, and an X-ray detector.

[0037] -The second rack portion has an open section and a first portion of a rack cover, wherein the first portion of the rack cover forms the open section.

[0038] -The first frame portion is movably supported relative to the second frame portion, such that the translational movement of the first frame portion relative to the second frame portion causes the translational movement of the bearing frame relative to the object being inspected. During this period, the rotational movement of the rotating frame and the flipping movement of the flipping frame are performed simultaneously, and when the object being inspected is in the open section, the second frame portion is stationary relative to the object being inspected.

[0039] The first frame portion may in particular include: a rotation support for the rotating frame relative to the tilting frame, and / or a rotation drive for driving the rotational movement of the rotating frame. The first frame portion may in particular include: a tilting support for the tilting frame relative to the supporting frame, and / or a tilting drive for driving the tilting movement of the tilting frame. The frame may in particular include: a linear support for the first frame portion relative to the second frame portion, and / or a translation drive for driving the translational movement of the first frame portion relative to the second frame portion. The translational movement of the first frame portion relative to the second frame portion may in particular be along a translation axis, and the translational movement of the supporting frame relative to the object being inspected may be along this translation axis. In particular, the first portion of the frame cover may define the opening section around the translation axis along the circumference of the opening section.

[0040] When the second gantry section is stationary relative to the object being examined, the opening section and the first part of the gantry cover are also stationary relative to the object being examined. This reduces the risk that translational movement of the support frame relative to the object being examined could affect examination accessories, such as those in the form of cables and / or hoses, placed on the patient.

[0041] In particular, it can be proposed that the rack has an internal area, and a cover is provided to isolate the internal area from the surrounding environment. Specifically, the support frame, the flip frame, the rotating frame, the X-ray source, and the X-ray detector can be located within the internal area. In particular, the first rack portion can have a second portion of the rack cover, wherein the support frame, the flip frame, the rotating frame, the X-ray source, and the X-ray detector are covered by the second portion of the rack cover.

[0042] The use of the indefinite article "one" or "a" does not preclude the possibility that the features involved can exist in multiple forms. The use of the term "unit" does not preclude the possibility that the object referred to in the term "unit" can have multiple components that are spatially separated from each other. Attached Figure Description

[0043] The invention is now described with reference to the accompanying drawings and embodiments. The illustrations in the drawings are schematic, highly simplified, and not necessarily to scale.

[0044] Figure 1 The image shows a computed tomography (CT) device.

[0045] Figure 2 A diagram showing the path derived from the flipping and rotating motions, along which the X-ray detector is guided.

[0046] Figure 3 A flowchart illustrating a method for detecting computed tomography (CT) imaging data is shown. Detailed Implementation

[0047] Figure 1 The computed tomography (CT) apparatus 1 is shown, which is configured to perform... Figure 3 The method shown for detecting computed tomography imaging data includes a computed tomography apparatus 1 having a rotating frame 24, a flipping frame 22, a support frame 21, an X-ray source 25, and an X-ray detector 28, wherein the X-ray detector 28 is a planar image detector.

[0048] The flipping frame 22 is connected to the bearing frame 21 by means of the flipping support T, and is flipped relative to the bearing frame 21 about the flipping axis AT, wherein the flipping axis AT is horizontal and perpendicular to the rotation axis AR.

[0049] When the flip angle TW is zero, the scanning plane of the computed tomography device 1 is in plane E1, and the X-ray detector 28 can rotate about the rotation axis AR on the circular path P1 by the rotation of the rotating frame 24 relative to the flip frame 22, wherein the rotation axis AR is oriented horizontally when plane E1 is vertical.

[0050] When the flip angle TW is not zero, the scanning plane of the computed tomography apparatus 1 is, for example, in plane E2, and the X-ray detector 28 can rotate about the rotation axis AR on a circular path P2 by rotating the frame 24 relative to the flip frame 22, wherein the rotation axis AR forms an angle with the horizontal direction Z, the value of which is equal to the value of the flip angle TW. The flip motion MT can also be performed between two different flip angles, each different from zero. The corresponding situation applies to the rotation of the X-ray source 25 about the rotation axis AR.

[0051] The computed tomography (CT) apparatus 1 has a bed 10 with a seat 11 and a support plate 12. The patient can lie on the support plate 12 such that the patient extends into the opening 9 of the gantry 20. In particular, the patient can lie on the support plate 12 such that the patient's head extends into the opening 9 and can be rotated MT in the direction of the patient's head position and / or in the direction of the feet position.

[0052] The computed tomography apparatus 1 has a tilt driver TD for driving the tilt motion MT of the tilt frame 22. The tilt driver TD in Figure 1 In the example shown, it is arranged in the foot area of ​​rack 20.

[0053] Furthermore, the computed tomography (CT) apparatus 1 has a flip angle sensor TN for detecting the actual value of the flip angle data. The CT imaging data includes multiple time-sequentially detected projection data sets, wherein each of the multiple time-sequentially detected projection data sets can be assigned a corresponding flip angle TW relative to the flip frame 22 of the support frame 21 based on the flip angle data, and a CT image can be calculated based on the multiple time-sequentially detected projection data sets and the flip angle data.

[0054] Simultaneously, the rotational motion MR of the rotating frame 24, the flipping motion MT of the flipping frame 22, and the translational motion MS of the support frame 21 relative to the object 13 are performed, wherein the translational motion MS of the support frame 21 is performed along the translational axis AS, wherein S3 computed tomography imaging data is detected from the object 13 by means of X-ray source 24 and X-ray detector 28, during which the rotational motion MR of the rotating frame 24, the flipping motion MT of the flipping frame 22, and the translational motion MS of the support frame 21 are performed simultaneously. The translational motion MS of the support frame 21 is driven relative to the base plane U by means of translation actuator 2U, wherein the object 13 is stationary relative to the base plane U. The translational axis AS is horizontal and perpendicular to the flipping axis AT.

[0055] The gantry 20 of the computed tomography (CT) apparatus 1 has a cover C for isolating the internal area of ​​the gantry from the surrounding environment, wherein the rotating frame 24, the X-ray source 25, and the X-ray detector 28 are located in the internal area. In this way, accidental contact with these components by patients and / or medical personnel can be avoided, and the associated risk of injury, especially during the rotational movement of the rotating frame 24, can be avoided.

[0056] Figure 2 A diagram showing path 12, derived from the flipping motion MT and the rotational motion MR, is shown, along which the X-ray detector 28 is guided.

[0057] The flipping motion MT of the flipping frame 22 includes a first flip angle change of at least 1° relative to the flip angle TW of the flipping frame 22 with respect to the supporting frame 21. The flipping motion MT of the flipping frame 22 also includes a second flip angle change of at least 1° relative to the flip angle TW of the flipping frame 22 with respect to the supporting frame 21, the second flip angle change occurring after the first flip angle change and pointing in the opposite direction to the first flip angle change of the flipping frame 22. The rotational motion MR of the rotating frame 24 includes a rotation angle change of the rotating frame 24 relative to the rotation angle RW of the flipping frame 22, wherein the rotation angle change begins simultaneously with the first flip angle change and ends simultaneously with the second flip angle change. The flipping motion MT of the flipping frame 22 is periodic, wherein the frequency of the flipping motion MT of the flipping frame 22 is greater than the rotational speed of the rotational motion MR of the rotating frame 24.

[0058] By simultaneously performing the flipping motion MT of the flipping frame 22 and the rotational motion MR of the rotating frame 24, the X-ray detector 28 is guided in a circular path P12 around the rotation axis AR, wherein the X-ray detector 28 performs an oscillating motion between planes E1 and E2. Path P12 is alternately tangent to circular paths P1 and P2, which is represented by a curve resembling a sinusoidal oscillation. The horizontal direction X is perpendicular to the horizontal direction Z and perpendicular to the vertical direction Y. The corresponding situation applies to the path derived from the flipping motion MT and the rotational motion MR, on which the X-ray source 25 is guided, and this path may differ from the path P12 guiding the X-ray detector 28, for example, with respect to the distance from the rotation axis AR.

[0059] exist Figure 2 In the example shown, the X-ray detector 28, acting as a planar image detector, extends in the horizontal direction Z greater than the examination object 13, which is the patient's head, extends in the horizontal direction Z. This can be achieved, for example, using a planar image detector whose horizontal direction Z extension is, for example, 30 cm or greater. Therefore, in Figure 2 In the example shown, a rotational angle change of approximately 190° is sufficient to detect computed tomography (CT) data of the entire patient's head. Therefore, translational motion MS is not necessary if only the patient's head needs to be examined.

[0060] By using a planar image detector as the X-ray detector 28, the ring width of the gantry 20 can be constructed relatively small compared to conventional computed tomography equipment. The ring width corresponds to the difference between the outer diameter of the gantry 20 in the scanning plane and the diameter of the opening 9, thereby reducing the overall external dimensions of the gantry 20.

[0061] Figure 3 A flowchart illustrating a method for detecting computed tomography (CT) imaging data is shown.

[0062] -Simultaneously, the rotational motion MR of the rotating frame 24 relative to the flipping frame 22 and the flipping motion MT of the flipping frame 22 relative to the supporting frame 21 are implemented, wherein the rotating frame 24 rotates around the rotation axis AR, and the flipping frame 22 flips around the flipping axis AT.

[0063] -The X-ray source 25 and X-ray detector 28 are connected to and fixed relative to the rotating frame 24, so that the X-ray source and X-ray detector simultaneously follow the rotational motion MR of the rotating frame 24 and the flipping motion MT of the flipping frame 22.

[0064] -In this process, computed tomography imaging data of S3 is detected by means of X-ray source 24 and X-ray detector 28, during which the rotational motion MR of the rotating frame 24 and the flipping motion MT of the flipping frame 22 described in S1 are performed simultaneously.
