Description

Technical Field

[0001] The utility model relates to the technical field of medical imaging, in particular to an imaging system. Background Art

[0002] Medical imaging systems can be used as a medical aid for diagnosis and treatment. To achieve better imaging results, imaging systems typically include multiple imaging devices, which can be used in series. Such imaging systems can combine the advantages of multiple imaging devices to achieve better imaging results.

[0003] Existing imaging systems typically include structural imaging devices and emission imaging devices. Such imaging systems can combine the imaging advantages of emission imaging devices with those of structural imaging devices. However, the structural imaging devices and emission imaging devices in existing imaging systems interfere with each other during the imaging process. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, an imaging system is provided. The imaging system includes a base, a structural imaging device, and an emission imaging device, wherein the structural imaging device and the emission imaging device are respectively arranged on the base; the emission imaging device includes a guide rail and a detection ring, and the detection ring includes a first arc-shaped detection portion and a second arc-shaped detection portion respectively slidably connected to the guide rail, and the first arc-shaped detection portion and the second arc-shaped detection portion are switchable between at least a first mating state and a second mating state; wherein, when the first arc-shaped detection portion and the second arc-shaped detection portion are switched to the first mating state, the detection ring is in a closed-loop state and the structural imaging device is in a closed state; and when the first arc-shaped detection portion and the second arc-shaped detection portion are switched to the second mating state, the detection ring is in an open-loop state and the structural imaging device is in an open state.

[0005] In the imaging system provided by the present invention, the detection ring can be switched between an open-loop state and a closed-loop state by switching the first arc-shaped detection portion and the second arc-shaped detection portion between the first matching state and the second matching state. When the detection ring is in the open-loop state, the emission imaging device does not participate in the imaging, and the structural imaging device can be in the open state. At this time, when the structural imaging device is used to detect the object to be inspected, since the detection ring is in the open-loop state, the first arc-shaped detection portion and the second arc-shaped detection portion can be far away from the structural imaging device, which effectively reduces the interference of the emission imaging device on the structural imaging device when imaging. When the detection ring is in the closed-loop state, the structural imaging device can be in the closed state, and the emission imaging device can detect the object to be inspected. At this time, since the structural imaging device is in the closed state, the interference of the structural imaging device on the emission imaging device when imaging is effectively reduced. Therefore, in such an imaging system, the mutual interference between the structural imaging device and the emission imaging device can be less. In addition, when the detection ring is in an open-loop state, the subject to be examined can enter the position to receive detection, for example, it can lie in the middle of the detection ring. When the detection ring is in a closed-loop state, the part of the subject to be examined that is located in the detection ring can be detected, and detection of local organs of the subject to be examined can be achieved. When such an emission imaging device is in use, since the detection ring can switch between an open-loop state and a closed-loop state, the subject to be examined can easily enter the detection ring to receive detection. Therefore, the detection ring can be designed to be smaller in size. Such a detection ring has a smaller detection aperture, which can achieve higher imaging resolution and better imaging effects for local organs. On this basis, such an emission imaging device can achieve a lightweight design, and the volume and cost of the overall device can be lower. Such an emission imaging device can also be more convenient when used for serial imaging with other structural imaging devices, so such an imaging system can be easier to implement.

[0025] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0026] According to one aspect of the present invention, an imaging system is provided. Figure 1 、 Figure 2 、 Figure 3 and Figure 4The imaging system may include a base 13, a structural imaging device 12 and an emission imaging device 11. The structural imaging device 12 and the emission imaging device 11 may be respectively arranged on the base 13. The base 13 may be designed into any suitable form as needed, and the structural imaging device 12 and the emission imaging device 11 may be respectively arranged on the base 13 by various suitable forms such as welding, threaded connection or clamping. The emission imaging device 11 may be a PET imaging device or any other suitable emission imaging device. The emission imaging device 11 may include a guide rail 100 and a detection ring 200, and the detection ring 200 may include a first arc-shaped detection portion 210 and a second arc-shaped detection portion 220 respectively slidably connected to the guide rail 100. Exemplarily, a sliding base may be provided on the guide rail 100, and the first arc-shaped detection portion 210 may be connected to the sliding base by various forms such as threaded connection, clamping or welding, and the first arc-shaped detection portion 210 may slide on the guide rail 100 along with the sliding base. Of course, the first arc-shaped detection portion 210 can also be directly slidably connected to the guide rail 100 through magnetic connection, snap connection or any other suitable form. The form in which the second arc-shaped detection portion 220 is slidably connected to the guide rail 100 can be the same as or different from the first arc-shaped detection portion 210, and will not be elaborated here. The first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 can switch between each other at least between a first matching state and a second matching state. Among them, when the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 switch to the first matching state, the detection ring 200 can be in a closed-loop state, and the structural imaging device 12 can be in a closed state; when the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 switch to the second matching state, the detection ring 200 can be in an open-loop state, and the structural imaging device 12 can be in an open state. The first curved detection portion 210 can be an arc of any angle, and the second curved detection portion 220 can be an arc structure that matches the arc of the first curved detection portion 210. The first curved detection portion 210 and the second curved detection portion 220 can be combined to form a closed loop, and there is no special limitation on the arc angle of the two. When the first curved detection portion 210 and the second curved detection portion 220 switch to a first mating state, the detection ring 200 can be in a closed loop state. At this time, at least a portion of the first curved detection portion 210 can be connected to the second curved detection portion 220 by various suitable means such as magnetic connection, clamping or threaded connection, so that the detection ring 200 is in a closed loop state; or at least a portion of the first curved detection portion 210 can be against the second curved detection portion 220, so that the detection ring 200 is in a closed loop state.When the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 switch to the second coordinated state, the detection ring 200 can be in an open loop state. At this time, the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 can be spaced apart from each other. For example, there can be a gap between the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 in the extension direction of the guide rail 100. Here, the structural imaging device 12 is in the off state, which means that the structural imaging device 12 does not participate in the detection and imaging of the subject 15. At this time, the structural imaging device 12 can be in the power-off state, or the subject 15 cannot enter the detection area of the structural imaging device 12, so that the structural imaging device 12 cannot image the subject 15. Here, the structural imaging device 12 is in the on state, which means that the structural imaging device 12 can detect and image the subject 15. At this time, it can be considered that the subject 15 can enter the detection area of the structural imaging device 12, and after the subject 15 enters the detection area of the structural imaging device 12, the subject 15 can be imaged by the structural imaging device 12. That is to say, in the present application, the structural imaging device 12 is in an on state or an off state, which does not limit the power on or off of the structural imaging device 12 .

[0027] In such an imaging system, the first curved detection portion 210 and the second curved detection portion 220 switch to a first coordinated state with each other, and the detection ring 200 is in a closed-loop state. At this time, the structural imaging device 12 is in a closed state. The detection ring 200 in the closed-loop state can detect the object 15 to be examined. At this time, the structural imaging device 12 is in a closed state, which can reduce interference with the imaging of the detection ring 200. When the detection ring 200 is in an open-loop state, it can be considered that the first curved detection portion 210 and the second curved detection portion 220 are spaced apart, that is, the distance between the first curved detection portion 210 and the second curved detection portion 220 is relatively far. Based on this, it can be achieved that when the first curved detection portion 210 and the second curved detection portion 220 switch to the second coordinated state with each other, the first curved detection portion 210 and the second curved detection portion 220 are respectively far away from the structural imaging device 12, which can effectively reduce the interference of the first curved detection portion 210 and the second curved detection portion 220 on the imaging of the structural imaging device 12. When such an imaging system performs detection imaging on the object 15, the imaging of the object 15 by the structural imaging device 12 and the emission imaging device 11 can be considered to be performed separately from each other. Therefore, when such an imaging system performs detection imaging on the object 15, the structural imaging device 12 can first perform detection imaging on the object 15, and then the emission imaging device 11 can perform detection imaging on the object 15. That is, the first curved detection portion 210 and the second curved detection portion 220 are first in the second coordinated state with each other, at which time the structural imaging device 12 performs detection imaging on the object 15. Subsequently, the first curved detection portion 210 and the second curved detection portion 220 switch to the first coordinated state with each other, and the detection ring 200 is in a closed loop state. At this time, the emission imaging device 11 performs detection imaging on the object 15, and the structural imaging device 12 is in a closed state. Alternatively, the emission imaging device 11 may first detect and image the object 15, and then the structural imaging device 12 may detect and image the object 15. That is, the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are first in a first coordinated state with each other, and the detection ring 200 is in a closed-loop state. At this time, the emission imaging device 11 detects and images the object 15, and the structural imaging device 12 is in a closed state. Subsequently, the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to a second coordinated state with each other, and at this time, the structural imaging device 12 can detect and image the object 15. When the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to the second coordinated state with each other, the detection ring 200 is in an open-loop state, and there is no restriction on the movement of the object 15. The object 15 can be simply and conveniently moved between the detection area of the structural imaging device 12 and the detection area of the emission imaging device 11.

[0028] In the imaging system provided by the present invention, the detection ring 200 can be switched between an open-loop state and a closed-loop state by switching the first curved detection portion 210 and the second curved detection portion 220 between a first coordinated state and a second coordinated state. When the detection ring 200 is in the open-loop state, the emission imaging device 11 does not participate in imaging, and the structural imaging device 12 can be in the open state. At this time, when the structural imaging device 12 is used to detect the object 15, since the detection ring 200 is in the open-loop state, the first curved detection portion 210 and the second curved detection portion 220 can be relatively far away from the structural imaging device 12, thereby effectively reducing interference caused by the emission imaging device 11 in imaging the structural imaging device 12. When the detection ring 200 is in the closed-loop state, the structural imaging device 12 can be in the closed state, and the emission imaging device 11 can detect the object 15. At this time, since the structural imaging device 12 is in the closed state, interference caused by the structural imaging device 12 in imaging the emission imaging device 11 is effectively reduced. Therefore, in such an imaging system, the mutual interference between the structural imaging device 12 and the emission imaging device 11 can be reduced. In addition, when the detection ring 200 is in an open-loop state, the subject 15 can enter the detection position, for example, it can lie in the middle of the detection ring 200. When the detection ring 200 is in a closed-loop state, the part of the subject 15 located in the detection ring 200 can be detected, and the detection of the local organs of the subject 15 can be achieved. When such an emission imaging device 11 is in use, since the detection ring 200 can switch between an open-loop state and a closed-loop state, the subject 15 can easily enter the detection ring 200 to receive detection. Therefore, the detection ring 200 can be designed to be smaller in size. Such a detection ring 200 has a smaller detection aperture, which can achieve higher imaging resolution and better imaging effects for local organs. On this basis, such an emission imaging device 11 can achieve a lightweight design, and the volume and cost of the overall device can be lower. Such an emission imaging device 11 can also be more convenient when used for serial imaging with other structural imaging devices 12, so such an imaging system can be easier to implement.

[0029] In one embodiment of the present invention, see Figure 3 and Figure 4The first curved detection portion 210 may include a first connection end 211 that is slidably connected to the guide rail 100, and the second curved detection portion 220 may include a second connection end 221 that is slidably connected to the guide rail 100. When the first curved detection portion 210 and the second curved detection portion 220 are switched to a first mating state, the first connection end 211 may at least partially abut against the second connection end 221. When the first curved detection portion 210 and the second curved detection portion 220 are switched to a second mating state, the first connection end 211 and the second connection end 221 may be spaced apart. Through reasonable structural design, when the first connection end 211 at least partially abuts against the second connection end 221, the first curved detection portion 210 and the second curved detection portion 220 can be combined into a closed loop, that is, the detection loop 200 can be closed. When the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 switch to the first mating state, the first connection end 211 and the second connection end 221 simply abut against each other, without providing a connection structure on the first connection end 211 and the second connection end 221. This can prevent the connection structure from interfering with the sliding of the first arc-shaped detection portion 210 and / or the second arc-shaped detection portion 220 on the guide rail 100. At the same time, such a detection ring 200 structure can be simpler and easier to implement, and the structure of the overall imaging system is also simpler. From the perspective of the imaging system, a simpler structure can also avoid internal electromagnetic interference and increase the stability of the overall system imaging.

[0030] For example, see Figure 3 and Figure 4 When the first curved detection portion 210 and the second curved detection portion 220 are switched to the first mating state, the first connection end 211 can be connected to the second connection end 221. The first connection end 211 can be connected to the second connection end 221 through various suitable means such as magnetic connection, threaded connection, or snap connection. When the first curved detection portion 210 and the second curved detection portion 220 are switched to the first mating state, the first connection end 211 is connected to the second connection end 221. In this way, the detection ring 200 can be more stable in the closed loop state, and the stability of the overall system can be improved.

[0031] For example, see Figure 3 and Figure 4The first curved detection portion 210 may include a first free end 212 away from the first connection end 211, and the second curved detection portion 220 may include a second free end 222 away from the second connection end 221. When the first curved detection portion 210 and the second curved detection portion 220 are switched to a first mating state, the first free end 212 is detachably connected to the second free end 222; when the first curved detection portion 210 and the second curved detection portion 220 are switched to a second mating state, the first free end 212 is spaced apart from the second free end 222. When the first curved detection portion 210 and the second curved detection portion 220 are switched to the first mating state, the first free end 212 may be detachably connected to the second free end 222 by snapping, threading, or other various means. A detachable connection structure is provided between the first free end 212 and the second free end 222, so that when the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to the first mating state, the first free end 212 can be detachably connected to the second free end 222. Since both the first free end 212 and the second free end 222 are away from the guide rail 100, such a detachable connection structure is easier to operate and is more convenient for repairing or replacing the detachable structure. In such an imaging system, the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 can more easily switch between the first mating state and the second mating state, and when the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to the first mating state, the closed loop state of the detection ring 200 can be more stable.

[0032] For example, in an embodiment not shown, a snap-fit portion may be provided on the first free end 212, and a snap-fit portion may be provided on the second free end 222. When the first curved detection portion 210 and the second curved detection portion 220 are switched to the first mating state, the snap-fit portion and the snap-fit portion may form a snap-fit. When the first curved detection portion 210 and the second curved detection portion 220 are switched to the first mating state, the first free end 212 is connected to the second free end 222 by snapping. In this way, the first free end 212 is detachably connected to the second free end 222, the overall structure is simpler, the connection and disassembly between the first free end 212 and the second free end 222 are more convenient, and the first curved detection portion 210 and the second curved detection portion 220 can switch between the first mating state and the second mating state more conveniently.

[0033] For example, see Figure 3When the detection ring 200 is in a closed-loop state, the detection ring 200 has a detection aperture D, and the detection aperture D is no greater than 50 cm. Taking the emission imaging device including the PET imaging device as an example, in the existing PET imaging device, the detection aperture of the detection ring is usually 80 cm to 100 cm. This is because the existing PET imaging device usually needs to image the whole body of the subject 15. In the emission imaging device 11 provided by the present invention, when the detection aperture D of the detection ring 200 is no greater than 50 cm, it can image the organs to be detected of the subject 15, for example, it can image the brain of the subject 15. In this way, the size of the emission imaging device 11 can be smaller, the overall cost can be lower, and the detection sensitivity and resolution can be higher. At the same time, since the first arc-shaped detection part 210 and the second arc-shaped detection part 220 can switch between the first matching state and the second matching state, even if the detection aperture D of the detection ring 200 is small, the object 15 can lie at the predetermined detection position when the detection ring 200 is in the open-loop state. Then, the first arc-shaped detection part 210 and the second arc-shaped detection part 220 switch to the first matching state and the detection ring 200 is in the closed-loop state to detect the object 15. That is to say, even if such an emission imaging device 11 is small in size, it is very convenient to image the detected organ of the object 15, and the situation that the object 15 is difficult to enter the detection ring 200 will not occur. Such an imaging system is more convenient for detecting and imaging the object 15.

[0034] For example, see Figure 3 and Figure 4 The first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 can both be semicircular. Such a detection ring 200 has a more stable structure, and the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 have a more regular structure and are easy to produce.

[0035] For example, see Figure 1 and Figure 2 The structural imaging device 12 may include a nuclear magnetic resonance imaging device. The nuclear magnetic resonance imaging device can perform multi-parameter, multi-angle and multi-directional imaging, and such an imaging system can achieve better imaging effects.

[0036] For example, see Figure 1 and Figure 2 The structural imaging device 12 may include a CT imaging device. The CT imaging device can provide cross-sectional images and has good density resolution, so the imaging effect of such an imaging system can be better.

[0037] According to another aspect of the present invention, an imaging method is provided, which can be applied to any imaging system described above.

[0038] For example, see Figure 5 , imaging methods may include:

[0039] Step S01: the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to a first matching state;

[0040] Step S02: The detection ring 200 detects the object 15;

[0041] Step S03: the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to a second matching state;

[0042] Step S04 : the structural imaging device 12 detects the object 15 .

[0043] For example, see Figure 6 , imaging methods may include:

[0044] Step S01: the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to a first matching state;

[0045] Step S02: The structural imaging device 12 detects the object 15;

[0046] Step S03: the first arc-shaped detection portion 210 and the second arc-shaped detection portion 220 are switched to a second matching state;

[0047] Step S04 : The detection ring 200 detects the object 15 .

They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

It should be understood that area-relative terms include not only the orientation of the components as described in the figures, but also different orientations in use or operation. For example, if the components in the drawings are inverted as a whole, the situation where the components are "above other components or features" or "above other components or features" will include the situation where the components are "below other components or structures" or "below other components or structures". Thus, the exemplary term "above" may include both the orientations "above" and "below".
