Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of medical equipment, and in particular to a data acquisition system component, a rack of a medical imaging system, and a medical imaging system. Background Art

[0002] In a computed tomography (CT) imaging system, a radiation source emits precisely collimated radiation to the object being detected, and the radiation is received by a detector after being attenuated by the object being detected. The detector can be in the form of an array, and each detector element in the array generates a corresponding electrical signal. These electrical signals are transmitted to a data acquisition system for data processing to generate a final image.

[0003] In the rack of the CT imaging system, the radiation source and the detector are arranged opposite to each other. During the imaging process, the radiation source and the detector rotate around the Z axis of the rack in the imaging plane (XY plane). In order to obtain high-quality images, it is necessary to increase the rotation speed of the radiation source and the detector. In the case of high-speed rotation, if the mass distribution at each position of the rack is uneven, it will cause vibration during the rotation process. This vibration will affect the service life of the components and bearings on the rack and reduce the image quality.

[0004] It should be noted that the above introduction to the technical background is only intended to provide a clear and complete description of the technical solution of the present application and to facilitate understanding by those skilled in the art. Summary of the invention

In addition, the term "according to" should be understood as "at least in part according to...", and the term "based on" should be understood as "at least in part based on...", unless the context clearly indicates otherwise.

[0034] Features described and / or shown for one embodiment may be used in one or more other embodiments in the same or similar manner, combined with features in other embodiments, or replace features in other embodiments. The term "includes / comprising" when used herein refers to the presence of a feature, an entirety, a step, or a component, but does not exclude the presence or addition of one or more other features, entireties, steps, or components.

[0035] The system for obtaining medical image data (medical imaging system) described herein includes a medical imaging device. The medical imaging device can be applicable to various medical imaging modalities, including but not limited to CT (computed tomography) equipment, PET (positron emission tomography)-CT or any other suitable medical imaging device.

[0036] The medical imaging system may include a separate computer device connected to the medical imaging device, or may include a computer device connected to the Internet cloud, wherein the computer device is connected to the medical imaging device or a storage device storing medical images via the Internet. The imaging method may be implemented independently or jointly by the aforementioned medical imaging device, the computer device connected to the medical imaging device, and the computer device connected to the Internet cloud.

[0037] Exemplarily, the embodiments of the present application are described below in conjunction with an X-ray computed tomography (CT) device. Those skilled in the art will appreciate that the embodiments of the present application may also be applicable to other medical imaging devices.

[0038] Figure 1 FIG. 1 is a schematic diagram of a CT imaging device according to an embodiment of the present application, schematically illustrating the CT imaging device 100. Figure 1 As shown, the CT imaging device 100 includes a scanning gantry 101 and a patient table 102. The scanning gantry 101 has an X-ray source 103 and a detector assembly 104. The X-ray source 103 and the detector assembly 104 are arranged opposite to each other, and the X-ray source 103 projects an X-ray beam toward the detector assembly 104.

[0039] The subject 105 can lie flat on the patient table 102 and move into the scanning gantry opening 106 along with the patient table 102. The detector assembly 104 receives the X-ray beam projected by the X-ray source 103 and attenuated by the subject 105 to obtain medical imaging data of the subject 105.

[0040] Figure 2 2 is a schematic diagram of a CT imaging system according to an embodiment of the present application, schematically showing a block diagram of a CT imaging system 200. Figure 2 As shown, the detector assembly 104 includes a detector 104a and a data acquisition system (DAS, Data Acquisition System) assembly 104b.

[0041] The detector 104a may be in the form of an array, including a plurality of detector units, which respectively sense the projected X-rays passing through the object 105 to be detected and generate electrical signals.

[0042] The data acquisition system of the DAS component 104b performs data processing on the detection results of the detector 104a. For example, the data acquisition system receives the electrical signals collected by the detector 104a and converts these signals into digital signals for subsequent processing. Of course, the role of the data acquisition system is not limited to this. The data acquisition system sometimes also performs partial subsequent processing. In some designs, the detector 104a can also be directly integrated into the data acquisition system.

[0043] The scanning gantry 101 includes a fixed portion and a rotating portion, and the rotating portion can rotate relative to the fixed portion around the central axis (Z axis) of the gantry. The aforementioned X-ray source 103 and detector assembly 104 can be arranged on the rotating portion of the scanning gantry 101. In addition, other components of the CT imaging device (such as a heat exchanger, a collimator, a power module, etc.) can also be arranged on the rotating portion.

[0044] During the scanning period for collecting X-ray projection data, the rotating part of the scanning gantry 101 drives the components mounted thereon to rotate at high speed around the Z axis.

[0045] The rotation of the scanning gantry 101 and the operation of the X-ray source 103 are controlled by a control mechanism 203 of the CT imaging system 200. The control mechanism 203 includes an X-ray controller 203a that provides power and timing signals to the X-ray source 103, and a scanning gantry motor controller 203b that controls the rotation speed and position of the scanning gantry 101.

[0046] The image reconstruction device 204 receives the projection data from the DAS component 104b and performs image reconstruction. The reconstructed image is transmitted as input to the computer 205, which stores the image in the mass storage device 206.

[0047] The computer 205 also receives commands and scanning parameters from an operator through a console 207. The console 207 has some form of operator interface, such as a keyboard, mouse, voice activated controller, or any other suitable input device. An associated display 208 allows the operator to observe the reconstructed images and other data from the computer 205.

[0048] The commands and parameters provided by the operator are used by the computer 205 to provide control signals and information to the DAS components 104b, the x-ray controller 203a, and the scanning gantry motor controller 203b. In addition, the computer 205 operates the patient table motor controller 209 to control the patient table 102 to position the subject 105 and the scanning gantry 101. In particular, the patient table 102 moves the subject 105 in whole or in part through the scanning gantry 101. Figure 1 The scanning gantry opening 106 is provided.

[0049] The above schematically illustrates the device and system for acquiring medical imaging data (or also referred to as medical images or medical image data) of an embodiment of the present application, but the present application is not limited thereto. The medical imaging device may be a CT device, a PET-CT device, or any other suitable imaging device. The storage device may be located in the medical imaging device, in a server outside the medical imaging device, in an independent medical imaging storage system (such as PACS, Picture Archiving and Communication System), and / or in a remote cloud storage system.

[0050] In addition, the medical imaging workstation can be set up locally in the medical imaging device, that is, the medical imaging workstation is set up near the medical imaging device, and the two can be located together in the scanning room, imaging department or the same hospital. The medical image cloud platform analysis system can be located away from the medical imaging device, for example, in the cloud that communicates with the medical imaging device.

[0051] As an example, after a medical institution completes an imaging scan using medical imaging equipment, the scanned data is stored in a storage device; a medical imaging workstation can directly read the scanned data and perform image processing through its processor. As another example, a medical image cloud platform analysis system can read medical images in a storage device through remote communication to provide "Software as a Service" (SAAS). SAAS can exist between hospitals, between hospitals and imaging centers, or between hospitals and third-party online diagnosis and treatment service providers.

[0052] In the embodiments of the present application, the term "object" can be equivalently replaced by "detected object", "scanned object", "object to be scanned", "patient" or "research object", which can be a person, an animal, or an object (e.g., luggage, etc.). The term "dynamic balance" can be equivalently replaced by "dynamic balance", and the term "static balance" can be equivalently replaced by "static balance". The term "scanning gantry" can be equivalently replaced by "gantry".

[0053] In addition, in the following description of the embodiments of the present application, for the convenience of explanation, the central axis of the scanning frame is called the Z-axis; the plane perpendicular to the Z-axis is called the rotation plane or the XY plane; the direction along the Z-axis or the direction parallel to it is called the "axial direction"; the radial direction centered on the Z-axis is called the "radial direction"; the direction around the Z-axis is called the "circumferential direction"; the side away from the Z-axis along the radial direction is called the "radial outer side", and the side close to the Z-axis along the radial direction is called the "radial inner side".

[0054] It should be noted that the above directions of the present application are only for the convenience of explaining the present application, and are not intended to limit the directions of the data acquisition system components, racks, medical imaging systems, etc. of the present application in manufacturing and use.

[0055] Embodiments of the first aspect

[0056] An embodiment of the present application provides a data acquisition system component, which is arranged in a gantry of a medical imaging system. Figure 3 Schematic diagram of a data acquisition system component according to an embodiment of the present application. Figure 3As shown, the data acquisition system (DAS) assembly 300 includes: a data acquisition system 1 , a first board 2 , a second board 3 and a connection part 4 .

[0057] The first plate 2 carries the data acquisition system 1; the second plate 3 is arranged opposite to the first plate 2; the connecting portion 4 is arranged between the first plate 2 and the second plate 3, and the connecting portion 4 is arranged along the height direction (such as Figure 3 One end of the connecting portion 4 in the axial direction as shown is connected to the first plate 2, and the other end of the connecting portion 4 in the height direction is connected to the second plate 3. The dynamic balance of the rack is adjusted by adjusting at least one of the height and the installation position of the connecting portion 4.

[0058] According to the above embodiment, the data acquisition system assembly 300 is arranged in the rack of the medical imaging system, including the data acquisition system 1, the first board 2 carrying the data acquisition system, the second board 3 arranged opposite to the first board 2, and the connecting portion 4 connecting the first board 2 and the second board 3, and the dynamic balance of the rack is adjusted by setting the height of the connecting portion 4 and / or the installation position of the connecting portion 4. Thus, the service life of the rack and the image quality can be guaranteed.

[0059] like Figure 3 As shown, the first plate 2 and the second plate 3 are arranged relative to each other in the axial direction. By increasing or decreasing the height of the connecting portion 4, the distance between the first plate 2 and the second plate 3 can be adjusted, thereby adjusting the mass distribution of the DAS assembly 300 in the axial direction. When the height of the connecting portion 4 is set to an appropriate height, the mass distribution of the rack in the axial direction can be uniform, thereby making the rack reach a state of dynamic balance. In addition, by adjusting the installation position of the connecting portion 4, the mass distribution of the DAS assembly 300 can also be adjusted, thereby making the rack reach a state of dynamic balance.

[0060] In some embodiments, the mass distribution of the DAS assembly 300 in the axial direction is related to the mass distribution of the radiation source (e.g., the aforementioned X-ray source 103) opposite to it. For example, ideally, it is desirable to make the center of mass of the DAS assembly 300 and the radiation source in each plane perpendicular to the axial direction be located at the center of the gantry. The present application is not limited thereto, and the gantry may also be considered to be in a state of dynamic balance if it can ensure that the gantry rotation achieves appropriate stability and the image quality meets the preset requirements.

[0061] In some embodiments, the data acquisition system 1 can be implemented in various ways. For example, the data acquisition system 1 can include a circuit board with electronic devices. The data acquisition system 1 can be mounted on the first board 2 in various ways. For example, it can be mounted on the first board 2 by a fixing component, such as a screw; or it can be mounted on the first board 2 by welding, clamping, etc.

[0062] Figure 4is another schematic diagram of the data acquisition system components of an embodiment of the present application. Figure 4 As shown, the first plate 2 is in a plate shape and is provided with a plurality of mounting holes, wherein some of the mounting holes may be holes for mounting the data acquisition system 1, for example.

[0063] In some embodiments, the first plate 2 may also be provided with an interface connected to the rotating part of the rack, so that the DAS assembly 300 can be installed on the rotating part of the rack, and when the rotating part rotates, the DAS assembly 300 is driven to rotate.

[0064] In some embodiments, the first plate 2 and the rotating part may be connected in a detachable manner, thereby facilitating replacement and maintenance of the DAS assembly 300 .

[0065] In some embodiments, the interface connecting the first board 2 and the rotating part can be a universal interface. Thus, the DAS assembly 300 can be installed on the rotating parts of different racks, or the rotating parts of the same rack can be installed with different models of DAS assemblies 300.

[0066] For example, the user can replace a 64-row detector assembly with a 32-row detector assembly, wherein the 64-row detector assembly includes 64 rows of detectors and DAS assemblies corresponding to the 64 rows of detectors, and the 32-row detector assembly includes 32 rows of detectors and DAS assemblies corresponding to the 32 rows of detectors. Since the height and / or installation position of the connection portion 4 of the DAS assembly 300 in the 32-row detector assembly is an appropriate height or an appropriate position, the rack can also achieve dynamic balance after the detector assembly is replaced. As a result, the process of replacing components inside the rack can be simplified, and on-site replacement of components can be achieved, which helps to improve user experience.

[0067] In some embodiments, Figure 4 As shown, the radial inner edge A1 of the first plate 2 may be substantially arc-shaped, thereby being able to match with a detector that is also arc-shaped without interfering therewith.

[0068] In some embodiments, Figure 4 As shown, the radially outer edge A2 of the first plate 2 may be polygonal. The present application is not limited thereto, and the specific shape of the edge A2 may be related to the layout of the components carried by the first plate 2.

[0069] In some embodiments, the first plate 2 may be in an axisymmetric shape, with the axis of symmetry extending in a radial direction. By arranging the first plate 2 in an axisymmetric form, it is helpful to evenly distribute the mass of the DAS assembly 300 in a circumferential direction.

[0070] In some embodiments, Figure 3 and Figure 4 As shown, the second plate 3 may include at least one first balance weight plate 31. The static balance of the frame is adjusted by increasing or decreasing the number of the at least one first balance weight plate 31.

[0071] like Figure 3 and Figure 4 As shown, the mass distribution of the DAS assembly 300 in the circumferential direction can be adjusted by increasing or decreasing the number of first counterweight plates 31. When the number of first counterweight plates 31 is set to an appropriate number, the mass distribution of the frame in the circumferential direction can be uniform, so that the frame reaches a static balance state.

[0072] In some embodiments, the at least one first counterweight plate 31 may be a stacked structure, thereby facilitating adjustment of the number of first counterweight plates 31. Figure 3 and Figure 4 As shown, the second plate 3 may include three first counterweight plates 31 that are stacked. The present application is not limited thereto, and the first counterweight plates 31 may also be other numbers or other arrangements.

[0073] In some embodiments, Figure 3 and Figure 4 As shown, the edge A3 of the first counterweight plate 31 may be polygonal. The present application is not limited thereto, and the specific shape of the edge A3 may be related to the layout of the components carried by the first plate 2 and the position of the connecting portion 4.

[0074] In some embodiments, the second plate 3 may be in an axisymmetric shape, with the axis of symmetry extending in the radial direction. By arranging the second plate 3 in an axisymmetric form, it is helpful to evenly distribute the mass of the DAS assembly 300 in the circumferential direction.

[0075] In some embodiments, Figure 3 As shown, the second plate 3 may carry a sensor 32. The sensor 32 may be a temperature sensor for detecting the temperature near the DAS component 300. The present application is not limited thereto, and the sensor 32 may also be a speed sensor for detecting the rotation speed of the DAS component 300.

[0076] In some embodiments, Figure 3 As shown, the second plate 3 may be provided with a handle 33 , thereby facilitating adjustment of the number of first weight plates 31 .

[0077] Figure 5 and Figure 6 Schematic diagram of the first plate 2, the second plate 3 and the connection part 4 of the embodiment of the present application. In some embodiments, the number of the connection part 4 can be multiple, thereby ensuring the connection strength between the first plate 2 and the second plate 3.

[0078] For example, Figure 5 and Figure 6 As shown, the connection part 4 may include at least one connection block (plenum block) 41 located at the end D1, D2 of the first plate 2 or the end D3, D4 of the second plate 3 and at least one connection column (column) 42 located at the middle position of the first plate 2 or the second plate 3. By providing the connection part 4 at both the end and the middle position of the first plate 2 or the second plate 3, the connection strength of the first plate 2 and the second plate 3 can be ensured.

[0079] In some embodiments, the connection block 41 may be substantially plate-shaped, and the connection column 42 may be substantially column-shaped. By arranging the connection block 41 at the end position, the connection area with the first plate 2 and the second plate 3 can be increased, thereby further improving the connection strength. By arranging the connection column 42 with a smaller cross-section at the middle position, the connection column 42 can be prevented from interfering with other components mounted on the first plate 2, thereby facilitating the layout of other components.

[0080] In some embodiments, on a plane perpendicular to the height direction (axial direction), the position and angle of the at least one connection block 41 and the at least one connection column 42 are symmetrical with respect to a first axis, and the first axis passes through the center of the frame and the center of the first plate 2 or the second plate 3. In other words, the first axis may extend in a radial direction. By setting the position and angle of the connection block 41 and the connection column 42 in an axisymmetric form, it is helpful to evenly distribute the mass of the DAS assembly 300 in the circumferential direction.

[0081] The present application is not limited thereto, and the connecting block 41 and the connecting column 42 may also be disposed at other positions, or the connecting portion 4 may only include the connecting block 41 or the connecting column 42, or the connecting portion 4 may also be in other forms.

[0082] In some embodiments, the connection portion 4 can be connected to the first plate 2 and the second plate 3 in various ways. For example, the connection portion 4 is connected to the first plate 2 and the second plate 3 through a fixing component, and the fixing component can be, for example, a screw, etc.; or the connection portion 4 is connected to the first plate 2 and the second plate 3 by welding, clamping, etc.

[0083] In some embodiments, the DAS assembly 300 may be an open structure, thereby facilitating ventilation and heat dissipation of the data acquisition system or other internal components of the DAS assembly 300. Figure 5 and Figure 6 As shown, there is a certain interval between adjacent connecting blocks 41, or adjacent connecting columns 42, or adjacent connecting blocks 41 and connecting columns 42, thereby forming an open structure. When the DAS component 300 rotates with the rotating part of the random frame, the circuit board of the data acquisition system can be cooled by natural wind.

[0084] Figure 7 FIG. 3 is another schematic diagram of the DAS component 300 according to an embodiment of the present application. Figure 7 As shown, the data acquisition system component 300 may further include a third plate 5. The third plate 5 includes at least one second counterweight plate 51, which is mounted on the first plate 2 or the second plate 3. The static balance or dynamic balance of the rack is adjusted by adjusting at least one second counterweight plate 51, wherein the weight of the second counterweight plate 51 is less than the weight of the first counterweight plate 31. By providing the third plate 5, the static balance and dynamic balance of the rack can be adjusted more accurately.

[0085] In some embodiments, the static balance of the frame can be adjusted by increasing or decreasing the number of the at least one second counterweight plate 51 .

[0086] In some embodiments, the dynamic balance of the rack can be adjusted by adjusting the position of at least one second counterweight plate 51 in the height direction.

[0087] For example, when designing and manufacturing the DAS assembly 300, the number of the first counterweight plates 31 and the height and / or installation position of the connecting portion 4 are adjusted to make the DAS assembly 300 meet the requirements of the static balance and dynamic balance of the rack. However, at the site of installing or replacing the DAS assembly 300, the original static balance or dynamic balance may be broken due to the influence of uncertain factors such as the cable position. In this case, more precise adjustments can be made by changing the number or setting height of the second counterweight plates 51 with smaller weight to overcome the influence of the above uncertain factors on the static balance and dynamic balance of the rack.

[0088] In some embodiments, Figure 7 As shown, the second counterweight plate 51 can be located at a position farther away from the center of the frame than the second plate 3. Thus, the second counterweight plate 51 can be prevented from interfering with other components. The present application is not limited thereto, and the second counterweight plate 51 can be located at other positions.

[0089] It is worth noting that the above only describes the components or modules related to this embodiment, but the present application is not limited thereto. The data acquisition system component may also include other components or modules, and the specific contents of these components or modules may refer to the relevant technology.

[0090] Furthermore, for simplicity, Figures 1 to 7 The connection or position relationship between the various components or modules is only exemplified, but it should be clear to those skilled in the art that various related technologies such as mechanical connection and bus connection can be used between the various components or modules.
