Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to single-photon emission computed tomography (SPECT) equipment. Background Technology

[0002] With the continuous development and advancement of technology, using medical imaging equipment, such as single-photon emission computed tomography (SPECT) devices, to scan patients has become one of the more common diagnostic and treatment methods. These devices typically include a gantry and a probe mounted on the gantry, through which the patient is scanned. However, the axial scanning field of view of these devices is relatively limited, requiring multiple bed movements to meet the needs of larger axial scans, such as whole-body bone scans, making the scanning process cumbersome and time-consuming. Utility Model Content

[0003] Therefore, it is necessary to provide a single-photon emission computed tomography (SPECT) device that can have a larger axial scanning field of view, thereby meeting the scanning requirements of larger axial dimensions, reducing the number of times the patient bed is moved during the scanning process, simplifying the scanning process, and shortening the scanning time.

[0004] A single-photon emission computed tomography (SPECT) device, the single-photon emission computed tomography device comprising:

[0005] frame;

[0006] The first probe module includes a first drive mechanism, a first turntable, and a first probe, wherein the first turntable is rotatably connected to the frame, and the first probe is connected to the first turntable; and

[0007] The second probe module includes a second turntable and a second probe, wherein the second turntable is rotatably connected to the frame and the second probe is connected to the second turntable;

[0008] The first driving mechanism is used to drive the first probe to move along a first direction, a second direction, and a third direction, and to drive the first turntable to rotate around the axis of the frame, wherein any two of the first direction, the second direction, and the third direction are perpendicular, and one of them is the axis of the frame.

[0009] In some embodiments, the first drive mechanism includes a first drive member mounted on the frame, the first drive member being connected to the first turntable and used to drive the first turntable to rotate about the axial direction of the frame.

[0010] In some embodiments, the first probe module includes a first slider connected to the first turntable and a second slider connected to the first probe, the first slider and the second slider slidingly engaging along the second direction.

[0011] In some embodiments, the first probe module includes a third slider connected to the first probe, and the third slider and the second slider are slidably engaged along the first direction.

[0012] In some embodiments, the first probe module includes a fourth slider connected to the first probe, the fourth slider and the third slider slidingly engaging in a third direction.

[0013] In some embodiments, the first driving mechanism includes a second driving member connected to the first turntable, a third driving member connected to the second driving member, and a fourth driving member connected to the third driving member. The second driving member is used to drive the first probe to move along the second direction, the third driving member is used to drive the first probe to move along the first direction, and the fourth driving member is used to drive the first probe to move along the third direction.

[0014] In some embodiments, the second probe module includes a second drive mechanism connected to the frame, the second drive mechanism being used to drive the second probe to move radially along the frame, move tangentially along the frame, and drive the second turntable to rotate axially about the frame.

[0015] In some embodiments, the second drive mechanism includes a fifth drive member mounted on the frame, a sixth drive member connected to the second turntable, and a seventh drive member connected to the sixth drive member. The fifth drive member is connected to the second turntable and is used to drive the second turntable to rotate about the axial direction of the frame. The sixth drive member is used to drive the second probe to move along the second direction, and the seventh drive member is used to drive the second probe to move along the third direction.

[0016] In some embodiments, both the first turntable and the second turntable are annular and coaxially arranged, and the first turntable and the second turntable are arranged at radial intervals along the frame.

[0017] In some embodiments, one of the second probe and the first probe is provided with a pin and the other with a socket. When the first probe is located at one end of the second probe along the axial direction of the frame, the pin can be inserted into the socket.

[0018] The aforementioned single-photon emission computed tomography (SPECT) device includes two probe modules. In the first probe module, a first drive mechanism can drive a first turntable to rotate around the gantry axis, thereby causing the first probe connected to the first turntable to also rotate around the gantry axis. Furthermore, the first drive mechanism can also drive the first probe to move along a first direction, a second direction, and a third direction; that is, the first probe can move and rotate around the gantry axis, as well as move radially and tangentially along the gantry. Thus, when the first drive mechanism drives the first probe and the first turntable, the combined movement of these actions adjusts the position of the first probe relative to the second probe, bringing the first probe to one end of the second probe along the gantry axis. This achieves the splicing of the two probes along the gantry axis, resulting in a larger axial scanning field of view. This meets the need for scanning larger axial dimensions, reduces the number of times the patient bed needs to be moved during the scanning process, simplifies the scanning process, and shortens the scanning time.

[0031] See Figures 1 to 2 An embodiment of this application provides a single-photon emission computed tomography (SPECT) device comprising a frame 100, a first probe module 200, and a second probe module 300. The first probe module 200 includes a first drive mechanism, a first turntable 220, and a first probe 210. The first turntable 220 is rotatably connected to the frame 100, and the first probe 210 is connected to the first turntable 220. The second probe module 300 includes a second turntable 320 and a second probe 310. The second turntable 320 is rotatably connected to the frame 100, and the second probe 310 is connected to the second turntable 320. The first drive mechanism is used to drive the first probe 210 to move along a first direction, a second direction, and a third direction, and to drive the first turntable 220 to rotate about the axial direction of the frame 100. Any two of the first, second, and third directions are perpendicular, and one of them is the axial direction of the frame 100.

[0032] The single-photon emission computed tomography (SPECT) device in the above embodiment includes two probe modules. In the first probe module 200, a first driving mechanism can drive a first turntable 220 to rotate around the axial direction of the frame 100, thereby driving the first probe 210 connected to the first turntable 220 to also rotate around the axial direction of the frame 100. In addition, the first driving mechanism can also drive the first probe 210 to move along a first direction, move along a second direction, and move along a third direction. That is, the first probe 210 can move along the axial direction of the frame 100, rotate around the axial direction of the frame 100, and move radially and tangentially along the frame 100. Thus, when the first drive mechanism drives the first probe 210 and the first turntable 220, the position of the first probe 210 relative to the second probe 310 is adjusted through the combination of the above movements, so that the first probe 210 reaches one end of the second probe 310 along the axial direction of the frame 100, thereby achieving the splicing of the two probes along the axial direction of the frame 100. This allows for a larger axial scanning field of view, thereby meeting the scanning requirements of a larger axial dimension, reducing the number of times the bed needs to be moved during the scanning process, simplifying the scanning process, and shortening the scanning time.

[0033] In the embodiment shown in the accompanying drawings, the first direction is the axial direction of the frame 100, the second direction is the tangential direction of the frame 100, and the third direction is the radial direction of the frame 100. The frame 100 has a scanning cavity with a circular cross-section, and the axial, tangential, and radial directions of the frame 100 are also the axial, tangential, and radial directions of the scanning cavity.

[0034] In other embodiments, the second direction may be the axial direction of the frame 100, or the third direction may be the axial direction of the frame 100. Subsequent embodiments will be described primarily with reference to the orientation shown in the accompanying drawings.

[0035] See Figures 1 to 2 In some embodiments, the first drive mechanism includes a first drive member mounted on the frame 100, the first drive member being connected to the first turntable 220 and used to drive the first turntable 220 to rotate about the axial direction of the frame 100.

[0036] Specifically, the first turntable 220 is embedded in the frame 100 and rotates with the frame 100 so that the first turntable 220 can rotate around the axis (i.e., the first direction) of the frame 100. The first driving component can be a motor or other components, and its power output end is directly or indirectly connected to the first turntable 220 to drive the first turntable 220 to rotate around the axis (i.e., the first direction) of the frame 100, thereby changing the position of the first probe 210 in the circumferential direction of the frame 100.

[0037] See Figures 1 to 2 In some embodiments, the first driving mechanism includes a second driving member connected to the first turntable 220, a third driving member connected to the second driving member, and a fourth driving member connected to the third driving member. The second driving member is used to drive the first probe 210 to move along a second direction, the third driving member is used to drive the first probe 210 to move along a first direction, and the fourth driving member is used to drive the first probe 210 to move along a third direction.

[0038] Specifically, the second, third, and fourth driving components can all be cylinders or linear motors. The first probe 210 is connected to the power output end of the fourth driving component, the fourth driving component is connected to the power output end of the third driving component, and the third driving component is connected to the power output end of the second driving component. The second driving component can be mounted on the first turntable 220. Therefore, the fourth driving component can drive the first probe 210 to move in a third direction, the third driving component can drive the fourth driving component and the first probe 210 to move together in a first direction, and the second driving component can drive the third driving component, the fourth driving component, and the first probe 210 to move together in a second direction. In this way, the position of the first probe 210 relative to the second probe 310 can be adjusted by moving in the above three directions and rotating around the axial direction of the frame 100, so as to realize the splicing of the two probes along the axial direction of the frame 100, meet the scanning requirements of larger axial dimensions, reduce the number of times the bed needs to be moved during the scanning process, simplify the scanning process, and shorten the scanning time.

[0039] See Figures 1 to 2 In some embodiments, the first probe module 200 includes a first slider 231 connected to the first turntable 220 and a second slider 232 connected to the first probe 210, wherein the first slider 231 and the second slider 232 slide in cooperation along a second direction.

[0040] Specifically, of the first slider 231 and the second slider 232, one has a slide rail extending along a second direction, and the other has a slider slidably connected to the slide rail. For example, in the embodiment shown in the attached drawings, the first slider 231 is a slide rail extending along the second direction; the second slider 232 is L-shaped, including a section extending along a first direction and a section extending along a third direction, the section extending along the third direction being slidably connected to the first slider 231. When the second driving member drives the first probe 210 to move along the second direction, the first slider 231 and the second slider 232 slide relative to each other to guide and limit the movement of the first probe 210, improving the smoothness of its movement.

[0041] In other embodiments, of the first slider 231 and the second slider 232, one is a groove extending along the second direction, and the other is a slider slidably mounted in the groove. In other embodiments, of the first slider 231 and the second slider 232, one is a guide post extending along the second direction, and the other is a sleeve slidably mounted in the guide post.

[0042] See Figures 1 to 2 In some embodiments, the first probe module 200 includes a third slider 233 connected to the first probe 210, and the third slider 233 and the second slider 232 slide in a first direction.

[0043] Specifically, of the third slider 233 and the second slider 232, one has a slide rail extending along the first direction, and the other has a slider slidably connected to the slide rail. For example, in the embodiment shown in the attached figure, the section extending in the first direction of the "L"-shaped second slider 232 is the slide rail. When the third driving member drives the first probe 210 to move along the first direction, the third slider 233 and the second slider 232 slide relative to each other to guide and limit the movement of the first probe 210, thereby improving the smoothness of its movement.

[0044] In other embodiments, of the third slider 233 and the second slider 232, one is a groove extending along the first direction, and the other is a slider slidably mounted in the groove. In other embodiments, of the third slider 233 and the second slider 232, one is a guide post extending along the first direction, and the other is a sleeve slidably mounted in the guide post.

[0045] See Figures 1 to 2 In some embodiments, the first probe module 200 includes a fourth slider 234 connected to the first probe 210, and the fourth slider 234 and the third slider 233 slide in a third direction.

[0046] Specifically, of the fourth slider 234 and the third slider 233, one has a slide rail extending along a third direction, and the other has a slider slidably connected to the slide rail. For example, in the embodiment shown in the attached figure, the fourth slider 234 is a slider. When the fourth driving member drives the first probe 210 to move along a third direction, the fourth slider 234 and the third slider 233 slide relative to each other to guide and limit the movement of the first probe 210, thereby improving the smoothness of its movement.

[0047] In other embodiments, of the fourth slider 234 and the third slider 233, one is a groove extending in a third direction, and the other is a slider slidably mounted in the groove. In other embodiments, of the fourth slider 234 and the third slider 233, one is a guide post extending in a third direction, and the other is a sleeve slidably mounted in the guide post.

[0048] In the embodiment shown in the attached figure, the first probe 210 is fixedly connected to the fourth slider 234, thereby indirectly slidingly connected to the third slider 233 along the third direction, thereby indirectly slidingly connected to the second slider 232 along the first direction, and thereby indirectly slidingly connected to the first slider 231 and the first turntable 220 along the second direction.

[0049] In the aforementioned embodiments, the first probe 210 is connected to the power output end of the fourth driving member, the fourth driving member is connected to the power output end of the third driving member, the third driving member is connected to the power output end of the second driving member, and the second driving member is fixedly mounted on the first turntable 220. In other embodiments, the second driving member can be fixedly mounted on the first turntable 220 or the first sliding member 231, and its power output end is connected to the second sliding member 232, indirectly driving the first probe 210 to move along the second direction by driving the second sliding member 232. The third driving member is fixedly mounted on the second sliding member 232, and its power output end is connected to the third sliding member 233, indirectly driving the first probe 210 to move along the first direction by driving the third sliding member 233. The fourth driving member is fixedly mounted on the third sliding member 233, and its power output end is connected to the fourth sliding member 234, indirectly driving the first probe 210 to move along the third direction by driving the fourth sliding member 234.

[0050] See Figures 1 to 2 In some embodiments, the second probe module 300 includes a second drive mechanism connected to the frame 100. The second drive mechanism is used to drive the second probe 310 to move radially along the frame 100, to move tangentially along the frame 100, and to drive the second turntable 320 to rotate axially around the frame 100.

[0051] Specifically, the second drive mechanism is used to drive the second probe 310 to move along the second direction and along the third direction; and to drive the second turntable 320 to rotate around the first direction, thereby driving the second probe 310 connected to the second turntable 320 to rotate around the first direction. By performing the above-mentioned movements of the second probe 310, its position can be adjusted as needed during the scanning process for better scanning.

[0052] See Figures 1 to 2 In some embodiments, the second drive mechanism includes a fifth drive member mounted on the frame 100, the fifth drive member being connected to the second turntable 320 and used to drive the second turntable 320 to rotate about the axial direction of the frame 100.

[0053] Specifically, the second turntable 320 is embedded in the frame 100 and rotates with the frame 100 so that the second turntable 320 can rotate around the axis of the frame 100 (i.e., the first direction). The fifth driving component can be a motor or other components, and its power output end is directly or indirectly connected to the second turntable 320 to drive the second turntable 320 to rotate around the axis of the frame 100 (i.e., the first direction).

[0054] See Figures 1 to 2In some embodiments, the second probe module 300 further includes a sixth drive member connected to the second turntable 320 and a seventh drive member connected to the sixth drive member. The sixth drive member is used to drive the second probe 310 to move along a second direction, and the seventh drive member is used to drive the second probe 310 to move along a third direction.

[0055] Specifically, both the sixth and seventh driving components can be selected from components such as cylinders or linear motors. The sixth driving component can be fixedly mounted on the second turntable 320. The second probe 310 is connected to the power output end of the seventh driving component, and the seventh driving component is connected to the power output end of the sixth driving component. Therefore, the seventh driving component can drive the second probe 310 to move in a third direction, and the sixth driving component can drive the seventh driving component and the second probe 310 to move together in a second direction.

[0056] See Figures 1 to 2 In some embodiments, the first turntable 220 and the second turntable 320 are both annular and coaxially arranged, and the first turntable 220 and the second turntable 320 are arranged at radial intervals along the frame 100.

[0057] Specifically, the first turntable 220 is located outside the second turntable 320, and both are annular in shape. This inner and outer arrangement can save space as much as possible, making the overall structure more compact. Of course, in other embodiments, the first turntable 220 and the second turntable 320 can also be staggered along the first direction.

[0058] See Figures 1 to 2 In some embodiments, the second probe module 300 includes a fifth slider 331 connected to the second turntable 320 and a sixth slider 332 connected to the second probe 310, wherein the fifth slider 331 and the sixth slider 332 are slidably engaged along a second direction.

[0059] Specifically, of the fifth slider 331 and the sixth slider 332, one has a slide rail extending along the second direction, and the other has a slider slidably connected to the slide rail. For example, in the embodiment shown in the attached drawings, the fifth slider 331 is a slide rail extending along the second direction. When the sixth driving member drives the second probe 310 to move along the second direction, the fifth slider 331 and the sixth slider 332 slide relative to each other to guide and limit the movement of the second probe 310, thereby improving the smoothness of its movement.

[0060] See Figures 1 to 2 In some embodiments, the second probe module 300 includes a seventh slider 333 connected to the second probe 310, and the seventh slider 333 and the sixth slider 332 slide in a third direction.

[0061] Specifically, of the seventh slider 333 and the sixth slider 332, one has a slide rail extending along a third direction, and the other has a slider slidably connected to the slide rail. For example, in the embodiment shown in the attached figure, the seventh slider 333 is a slider. When the seventh driving member drives the second probe 310 to move along a third direction, the seventh slider 333 and the sixth slider 332 slide relative to each other to guide and limit the movement of the second probe 310, thereby improving the smoothness of its movement.

[0062] In the embodiment shown in the attached figure, the second probe 310 is fixedly connected to the seventh slider 333, thereby indirectly slidably connected to the sixth slider 332 along the third direction, and thereby indirectly slidably connected to the fifth slider 331 and the second turntable 320 along the second direction.

[0063] In the aforementioned embodiments, the second probe 310 is connected to the power output end of the seventh driving member, the seventh driving member is connected to the power output end of the sixth driving member, and the sixth driving member is fixedly mounted on the second turntable 320. In other embodiments, the sixth driving member can be fixedly mounted on the second turntable 320 or the fifth sliding member 331, and its power output end is connected to the sixth sliding member 332, thereby indirectly driving the second probe 310 to move along the second direction by driving the sixth sliding member 332. The seventh driving member is fixedly mounted on the sixth sliding member 332, and its power output end is connected to the seventh sliding member 333, thereby indirectly driving the second probe 310 to move along a third direction by driving the seventh sliding member 333.

[0064] In other embodiments, the fourth slider 234 can be removed, and the first probe 210 can be directly fixedly connected to the third slider 233. A slider that slides and engages with the second slider 232 along the third direction can be provided. This slider and the first slider 231 slide and engage along the second direction. In other words, the guide structure for the first probe 210 to move along the second and third directions can be set to be similar to that of the second probe 310. The corresponding driving component can be adjusted accordingly.

[0065] In other embodiments, an additional driving member can be added, which is mounted on the fourth sliding member 234, and the power output end of the driving member is connected to the first probe 210 to drive the first probe 210 to move along the second direction. That is, the first probe 210 can be directly driven by the driving member to move along the second direction, and can also be indirectly driven by the aforementioned second driving member to move along the second direction. Based on this embodiment, the previous embodiment can be combined, that is, the first probe 210 can also move along the second direction and the third direction at the first sliding member 231.

[0066] In other embodiments, the fourth slider 234 can be removed, and the first probe 210 can be directly fixedly connected to the third slider 233. The third slider 233 is configured to be telescopic in a third direction. The first probe 210 can be moved in a third direction by the telescopic movement of the third slider 233 itself.

[0067] See Figures 1 to 2 In some embodiments, one of the second probe 310 and the first probe 210 is provided with a pin and the other with a socket. When the first probe 210 is located at one end of the second probe 310 along the axial direction (i.e., the first direction) of the frame 100, the pin can be inserted into the socket.

[0068] Thus, when the first probe 210 reaches the end of the second probe 310 that is away from the frame 100 along the first direction, and the two probes are spliced ​​along the axial direction of the frame 100, the two probes can be locked by inserting a pin into the socket, so as to achieve uninterrupted scanning along the axial direction of the frame 100.

[0069] Preferably, multiple sets of pins and sockets can be provided to further enhance the locking accuracy and stability of the second probe 310 and the first probe 210.

[0070] See Figures 1 to 2 The single-photon emission computed tomography (SEPCT) device in this application embodiment has two operating modes, namely: Figure 1 The short axis pattern shown and Figure 2 The long axis mode is shown. When the scanning size along the axis of the frame 100 is small, the short axis mode can be selected to work. When the scanning size along the axis of the frame 100 is large, the long axis mode can be switched to work.

[0071] Taking the embodiment shown in the attached figure as an example, when switching from short-axis mode to long-axis mode, the first drive mechanism first moves the first probe 210 along the second direction and / or the third direction, aligning it with the second probe 310 in the second and third directions. Then, the first probe 210 moves along the first direction towards the end away from the frame 100, leaving space to avoid the second probe 310. Next, the first turntable 220 rotates around the first direction, reaching the end of the second probe 310 away from the frame 100 along the first direction. Finally, the first turntable 220 moves along the first direction towards the second probe 310 until the pin is inserted into the socket to lock it in place. Afterward, the two probes can scan in long-axis mode. During scanning in long-axis mode, the two probes are driven by their respective drive mechanisms, causing them to move and / or rotate synchronously.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
