Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a scanning object support device, a docking device, and a medical imaging system. Background Technology
[0002] Scanning devices are an important component of medical imaging systems. They scan patients non-invasively to acquire medical images of anatomical tissues of interest, assisting doctors in diagnosis. For example, computed tomography (CT) uses precisely collimated X-ray beams, gamma rays, etc., along with highly sensitive detectors to perform a series of cross-sectional scans around a specific part of the body. It features fast scanning time and clear images, and can be used to examine a variety of diseases.
[0003] The object support device is another important component of a medical imaging scanning system. It is responsible for raising and lowering the object and transporting it to the scanning position within the scanning device. The object support device includes a support platform. During scanning, the support platform can move towards the scanning device (this direction of movement can be called the removal direction) to move the object to the appropriate scanning position. After scanning is completed, the support platform can move in the opposite direction to the removal direction to bring the object back to its original position.
[0004] Typically, the subject being scanned (e.g., a patient) needs to lie down on or get off the support platform during the scan. However, for subjects with limited mobility (e.g., critically ill, paralyzed, or fractured patients), additional measures (such as stretchers) are required to assist the subject in getting on and off the support platform, which may injure the subject. Other measures may involve using a movable subject support device or a movable scanning device, which can be moved together during the imaging scan. Utility Model Content
[0005] The inventors discovered that during the scanning process, the movable object support device's support platform carries the object and moves and extends into the scanning device. The weight of the support platform and the object deviates from the main body of the object support device, meaning the overall center of gravity of the object support device shifts. This can easily lead to an imbalance in the load of the object, potentially causing the object support device to tilt towards the side closest to the scanning device. This instability can negatively impact the imaging quality. Furthermore, operators may find it difficult to move the movable object support device to a suitable position; the extended support platform may collide with the scanning device or become too close to one side of the device, requiring repositioning or realigning the object support device with the scanning device, thus affecting the efficiency or quality of the imaging operation.
[0006] To address at least one of the aforementioned technical problems or other similar issues, embodiments of this application provide a scanning object support device, a docking device, and a medical imaging system. Even with a movable scanning object support device, it can be correctly docked with the scanning device to balance the load on the scanning object and effectively maintain the stability of the scanning object support device.

[0015] In some embodiments, a fixing hole is provided in the ground; when the pressing device is pressed, the fixing rod is inserted into the fixing hole to fix the scanning object support device in the longitudinal direction; when the pressing device is returned to the unpressed state, the fixing rod separates from the fixing hole.
[0016] According to a second aspect of the present application, a docking device is provided for connecting a scanning object support device and a scanning device; the docking device includes: a body portion fixed to the ground or the scanning device, having a connecting rod or a connecting hole arranged longitudinally along the scanning object support device; the connecting hole or connecting rod can be fixedly connected to the connecting hole or connecting rod of the scanning object support device.
[0017] In some embodiments, the connecting rod includes a cylindrical body and a conical head; at least two connecting holes or the connecting rod are provided in the transverse direction of the docking device.
[0018] In some embodiments, the docking device further includes a camera located at the front end of the connecting rod or inside the connecting hole; wherein the image acquired by the camera is displayed on a display unit to guide the movement of the scanning object support device.
[0019] In some embodiments, the docking device further includes a docking switch located on the main body; the docking switch is triggered when the scanning object support device and the scanning device are successfully docked.
[0020] According to a third aspect of the embodiments of this application, a medical imaging system is provided, the system including a scanning device, a scanning object support device as described above, and a docking device as described above.

Furthermore, the term "the" should be understood to include both the singular and plural forms, unless the context explicitly indicates otherwise. Additionally, the term "according to" should be understood as "at least partially based on…," and the term "based on" should be understood as "at least partially based on…," unless the context explicitly indicates otherwise.
[0038] Features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, combined with features in other embodiments, or substituted for features in other embodiments. The term "comprising / including" as used herein means the presence of a feature, integral, step, or component, but does not exclude the presence or addition of one or more other features, integrals, steps, or components.
[0039] The scanning apparatus (i.e., medical imaging scanning system, imaging scanning device) described in this application can be applied to various medical imaging modalities, including but not limited to computed tomography (CT), magnetic resonance imaging (MRI), C-arm imaging, positron emission tomography (PET), single photon emission computed tomography (SPECT), or any other suitable medical imaging device.
[0040] Exemplary examples are described below with reference to X-ray computed tomography (CT) imaging systems. Those skilled in the art will understand that embodiments of this application can also be applied to other medical imaging scanning systems.
[0041] Figure 1 This is a schematic diagram of a CT device according to an embodiment of this application, illustrating the CT device 100. Figure 1 As shown, the CT equipment 100 includes a scanning gantry 101 and a patient table 102 (e.g., a scanning bed); the scanning gantry 101 has an X-ray source 103 that projects an X-ray beam toward a collimator or detector assembly 104 on the opposite side of the scanning gantry 101. A subject (also called a scanned object) 105 can lie supine on the patient table 102 and moves into the scanning gantry opening 106 as the patient table 102 moves; medical imaging data of the subject 105 can be obtained by scanning with the X-ray source 103.
[0042] Figure 2 This is a schematic diagram of a CT imaging system according to an embodiment of this application, illustrating a block diagram of the CT imaging system 200. Figure 2 As shown, the detector assembly 104 includes multiple detector units 104a and a data acquisition system (DAS) 104b. The multiple detector units 104a sense projected X-rays passing through the object being detected 105.
[0043] DAS104b converts the collected information into projection data based on the sensing of detector unit 104a for subsequent processing. During the scan that acquires X-ray projection data, the scanning gantry 101 and the components mounted thereon rotate around the rotation center 101c.
[0044] The rotation of the scanning gantry 101 and the operation of the X-ray source 103 are controlled by the 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 rotational speed and position of the scanning gantry 101. The image reconstruction unit 204 receives projection data from the DAS 104b and performs image reconstruction. The reconstructed image is transmitted as input to the computer 205, which stores the image in a mass storage device 206.
[0045] Computer 205 also receives commands and scanning parameters from the operator via console 207. Console 207 has some form of operator interface 2071, such as a keyboard, mouse, or voice-activated controller. Console 207 may also have input devices such as docking switches 2072. Furthermore, console 207 may have other suitable input devices. An associated display 208 allows the operator to view reconstructed images and other data from computer 205. Commands and parameters provided by the operator are used by computer 205 to provide control signals and information to DAS 104b, X-ray controller 203a, and scanning gantry motor controller 203b. Additionally, computer 205 operates patient table motor controller 209 to control patient table 102 to position the examination object 105 and scanning gantry 101. Specifically, patient table 102 moves the examination object 105 wholly or partially through... Figure 1 The scanning rack opening is 106.
[0046] The above illustrations depict devices and systems for acquiring medical imaging data (or medical images or medical image data) according to embodiments of this application, but this application is not limited thereto. Medical imaging devices may be CT scanners, PET-CT scanners, or any other suitable imaging equipment. Storage devices may be located within the medical imaging device, on a server outside the medical imaging device, in a standalone medical image storage system (such as a Picture Archiving and Communication System, PACS), and / or in a remote cloud storage system.
[0047] Furthermore, medical imaging workstations can be located locally on the medical imaging equipment, meaning they are situated close to the equipment, and both can be located in the same scanning room, radiology department, or within the same hospital. Meanwhile, the medical image cloud platform analysis system can be located away from the medical imaging equipment, for example, in the cloud where it communicates with the equipment.
[0048] 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 remotely access medical images stored in the storage device to provide "Software as a Service" (SaaS). SaaS can exist between hospitals, between hospitals and imaging centers, or between hospitals and third-party online medical service providers.
[0049] The above illustrations of medical imaging scanning are presented in detail below with reference to the accompanying drawings. In the following embodiments, a CT scanner is used as an example for illustration; however, this description is equally applicable to other medical devices.
[0050] Figure 3 This is a schematic diagram of the configuration of a medical imaging system according to an embodiment of this application, as shown below. Figure 3 As shown, the medical imaging system 300 includes a scanning device 301, a movable object support device 302, and a docking device 303. The object support device 302 is connected to the scanning device 301 via the docking device 303, thereby connecting the object support device 302 and the scanning device 301 together.
[0051] In some embodiments, the medical imaging system 300 may also include other components not shown, which may be referred to in detail elsewhere. Figure 1 and Figure 2 Additionally, scanning device 301 can also be referenced. Figure 1 and Figure 2 Alternatively, refer to relevant technologies.
[0052] The medical imaging system 300 will be further described below from the perspective of the scanning object support device 302.
[0053] Figure 4 This is a schematic diagram of a scanning object support device according to an embodiment of this application. Figure 4As shown, the scanning object support device 302 includes a support platform 3021 for carrying the scanning object, a lifting drive unit 3022 for carrying the support platform 3021, a base 3023 for carrying the lifting drive unit 3022, a moving part 304 mounted on the base 3023 and capable of moving the scanning object support device 302 as a whole, and a fixing part 305 for fixing the scanning object support device 302. Figure 4 Only some components are shown in the image) and the connecting part 306 for docking with the docking device 303. Figure 4 (The location is shown only schematically).
[0054] The support platform 3021 is used to support the scanning object. The scanning object can lie flat on the upper surface of the support platform 3021, and the position of the scanning object relative to the scanning device 301 can be adjusted by moving the support platform 3021. The support platform 3021 has a movable support part 3024, which can move along the length direction of the support platform 3021, that is, along the x-axis direction. Figure 4 The object is moved (in the x1 and x2 directions as shown) to adjust its position along the x-axis, so that it is positioned at the scanning location of the scanning device 301. Figure 4 As shown, the movable support 3024 is in the initial position, and the scanning object lying flat on the movable support 3024 is within the range of the support platform 3021 in the vertical direction.
[0055] Figure 5 This is another schematic diagram of the scanning object support device according to an embodiment of this application. For example... Figure 5 As shown, the movable support 3024 can move along the x1 direction and at least partially extend beyond the vertical range of the support platform 3021, thereby moving the scanned object to the scanning position. After scanning is completed, the movable support 3024 can move along the x2 direction to return to its initial position.
[0056] In this embodiment, the scanning object support device 302 can also be referred to as a "scanning bed," "medical bed," "patient table," etc., and the movable support part 3024 of the support platform 3021 can also be referred to as a "bed board." This application does not impose any limitations on this. The support platform 3021 is a rectangular plate with uniform thickness and is used to support the scanning object, for example, the scanning object lies flat on the support platform 3021 in a supine position.
[0057] In this embodiment, the movable support 3024 can also move the scanned object in the longitudinal direction (i.e., the x-axis direction) of the support platform 3021. The support platform 3021 can be made of a material with low X-ray attenuation, such as carbon fiber composite material, but this embodiment is not a limitation thereof.
[0058] like Figure 4and Figure 5 As shown, the lifting drive unit 3022 is used to support the support platform 3021 and can adjust the vertical height of the support platform 3021 to adjust the position of the scanned object in the vertical direction, that is, the position in the y-axis direction. Figure 4 (The y1 and y2 directions are shown in the diagram).
[0059] like Figure 4 and Figure 5 As shown, the movable part 304 is mounted on the base 3023 and enables the entire scanning object support device 302 to move. The movable part 304 includes a plurality of casters disposed on the underside of the base 3023, the plurality of casters being positioned in the outward direction of the movement of the support platform 3021 toward the scanning device 301. Figure 4 The first caster 3041 is located on the x1 direction side of the base 3023 (that is, the side of the object support device 302 that is closer to the scanning device 301 during scanning), and the second caster 3042 is located on the opposite side of the movement direction (that is, the side of the object support device 302 that is farther away from the scanning device 301 during scanning). That is, the first caster 3041 is located on the x1 direction side of the base 3023 or the side closer to the scanning device 301, and the second caster 3042 is located on the x2 direction side of the base 3023 or the side farther away from the scanning device 301.
[0060] In the embodiments of this application, such as Figure 5 As shown, after at least part of the scanned object is removed from the support platform, the center of gravity of the movable scanned object support device 302 will change. The center of gravity may deviate from the center of the scanned object support device 302 and lean towards the first caster 3041, which may easily lead to the problem of difficulty in balancing the load of the scanned object, causing the scanned object support device 302 to tilt. In addition, the operator may find it difficult to move the scanned object support device 302 to a suitable position. That is, the extended support platform 3021 may collide with the scanning device 301 or be too close to one side of the scanning device 301, which may require repositioning or affect the image quality acquired by subsequent imaging scans.
[0061] In this embodiment, the connecting part 306 effectively connects the scanning object support device 302 and the scanning device 301, and maintains the stability of the scanning object support device, avoiding docking failure and thus improving the efficiency and image quality of the imaging scanning operation. Furthermore, in this embodiment, the fixing part 305 can also be used to fix the scanning object support device 302, further enhancing its stability.
[0062] The fixing part 305 will be described by example below. In this application, the fixing part 305 is optional. For example, only the connecting part 306 can be provided without the fixing part 305, or the fixing part 305 can be used in other ways such as electromagnetic attraction, adhesion, snap-fit, etc. This application is not limited to these.
[0063] In some embodiments, the fixing part 305 is located at the end of the base 3023 away from the scanning device 301, and includes a fixing rod 3051 disposed on the base 3023 and arranged in a vertical direction (i.e., perpendicular to the base 3023 or perpendicular to the ground), and a fixing hole 3052 disposed at the fixing position of the scanning object support device 302. By inserting the fixing rod 3051 into the fixing hole 3052, the scanning object support device 302 can be fixed at the fixing position, preventing the scanning object support device 302 from moving along the x-axis. The following description will take the fixing position being located on the ground as an example, but this application is not limited thereto.
[0064] Figure 6 This is a partial schematic diagram of a scanning object support device according to an embodiment of this application, exemplarily showing some components of the fixing part 305. For example... Figure 6 As shown, the fixing rod 3051 is disposed on the side of the base 3023 facing the position to be fixed 601 (i.e., the lower side of the base 3023 facing the ground), and is located at one end of the second caster 3042 (i.e., the end away from the scanning device 301). That is, the fixing rod 3051 is disposed on the y2 direction side (lower side) of the base 3023 and on the x2 direction side (right side) of the second caster 3042. The fixing hole 3052 is disposed on the ground and located at the position to be fixed 601 of the scanning object support device 302.
[0065] For example, if the fixing rod 3051 and the fixing hole 3052 are in the vertical direction (i.e. Figure 6 Corresponding to the position in the y1-y2 direction, the fixing rod 3051 is inserted into the fixing hole 3052. At this time, the scanning object support device 302 is fixed at the position to be fixed 601 by the action of torque, preventing it from moving along the x-axis and z-axis directions.
[0066] For example, if the positions of the fixing rod 3051 and the fixing hole 3052 do not correspond in the vertical direction, the fixing rod 3051 cannot be inserted into the fixing hole 3052. In this case, it is necessary to adjust the position of the scanning object support device 302 to ensure that the fixing rod 3051 can be inserted into the fixing hole 3052.
[0067] Therefore, after the scanning object support device 302 and the docking device 303 are docked, the scanning object support device 302 can be further fixed by the fixing rod 3051 and the fixing hole 3052, and scanning is prevented from starting before the scanning object support device 302 is fixed, thus further improving safety.
[0068] In some embodiments, the fixing rod 3051 may be formed of metal, such as steel, iron, or other materials, and this application is not limited thereto.
[0069] In some embodiments, the number of fixing rods 3051 is not less than two, and the number of fixing holes 3052 is not less than the number of fixing rods 3051. For example, two fixing rods 3051 are provided in the transverse direction of the scanning object support device 302, that is, two fixing rods 3051 are provided in the z-axis direction of the scanning object support device 302, and two fixing holes 3052 are also provided in the ground along the z-axis direction. The fixing rods 3051 can be inserted into the fixing holes 3052. This application is not limited to this. Multiple fixing rods 3051 and fixing holes 3052 can also be arranged in the longitudinal direction, that is, in the x-axis direction, or in other directions. This application does not limit this.
[0070] In some embodiments, the fixing part 305 further includes a pressing device 307 that moves the fixing rod 3051 in a vertical direction (i.e., perpendicular to the ground). The pressing device 307 is located on the lower side of the scanning object support device 302, i.e., the y2 direction side. Thus, the fixing rod 3051 can be inserted into the fixing hole 3052 by pressing the device 307, further improving the convenience of operation.
[0071] like Figure 6 As shown, for example, the pressing device 307 includes a pedal 3071 and a guide 3072. The pedal 3071 is mounted to the base 3023 and is located on the x2 side of the base 3023. The pedal 3071 has a three-section structure, including a pivot connection portion 3073 rotatably connected to the base 3023, a pedal portion 3075 for the operator to press or step on, and an intermediate portion 3074 connecting the pivot connection portion 3073 and the pedal portion 3075. The intermediate portion 3074 is connected to the end face of the base 3023 by a spring and is used to reset the pedal 3071. The middle portion 3074 of the pedal 3071 is connected to the fixing portion 3076 of the supporting fixing rod 3051 via a plate-shaped connecting rod. A double-click release mechanism (not shown) can be provided between the two. That is, when the user presses the pedal for the first time, the fixing portion 3076 of the fixing rod 3051 moves downwards and inserts the fixing rod 3051 into the fixing hole 3052 to a fixed position. When the user presses the pedal 3071 for the second time, the pedal 3071 moves out of the fixing hole 3052 under the action of a spring to return to the release position. After the pedal 3071 is pressed by the operator, the fixing rod 3051 can be moved towards the fixing hole 3052 via a pivot. The guide member 3072 guides the fixing rod 3051, restricting the direction of movement of the fixing rod 3051 towards the fixing hole 3052, or restricting the direction of movement of the fixing rod 3051 away from the fixing hole 3052.
[0072] In some embodiments, when the pressing device 307 is pressed, the fixing rod 3051 is inserted into the fixing hole 3052 to fix the scanning object support device 302 in the longitudinal (x-axis direction) and transverse (z-axis direction); when the pressing device 307 is returned to the unpressed state, the fixing rod 3051 separates from the fixing hole 3052, thereby releasing the restriction on the scanning object support device 302 in the longitudinal (x-axis direction) and transverse (z-axis direction).
[0073] For example, guide component 3072 is Figure 6 The two columns are shown. The guide 3072 restricts the fixing rod 3051 from moving (moving downward) towards the fixing hole 3052 along the y2 direction, or restricts the fixing rod 3051 from moving away from the second anchoring part 1052 (moving upward) along the y1 direction. This embodiment of the application is not intended to be limiting.
[0074] Thus, by means of the pedal 3071 and the guide 3072, the scanning object support device can be fixed with a simple structure, and the fixing rod 3051 can be inserted into the fixing hole 3052. In addition, the fixing rod 3051 and the fixing hole 3052 can be separated by a restoring element (e.g., a spring), thereby restoring the pressing device 307 to the unpressed state, which can further improve the convenience of operation.
[0075] The fixing part 305 of this application has been described above by way of example. The connecting part 306 will be described by way of example below.
[0076] Figure 7 This is a schematic diagram of the connection portion of the scanning object support device according to an embodiment of this application. Figure 7 As shown, the connecting part 306 is disposed at one end of the base 3023 near the scanning device 301 and above the first caster 3041, that is, the connecting part 306 is disposed on the x1 direction side of the base 3023 and on the y1 direction side of the first caster 3041. The connecting part 306 includes a connecting hole or a connecting rod disposed longitudinally along the scanning object support device 302, the connecting hole or connecting rod being able to be fixedly connected to a docking device fixed to the scanning device. Figure 7 The connection hole 3061 is only schematically shown in the figure, and this application is not limited thereto.
[0077] In some embodiments, at least two connecting holes or connecting rods are provided in the transverse direction (i.e., the z-axis direction) of the scanning object support device 302, or in the vertical direction (i.e., the y-axis direction or the direction perpendicular to the ground) of the scanning object support device 302, or in other directions of the scanning object support device 302. This application does not limit this to any of these embodiments.
[0078] In some embodiments, if the docking device 303 is provided with connecting rods, then the scanning object support device 302 is provided with connecting holes, and the number of connecting rods of the docking device 303 is no more than the number of connecting holes of the scanning object support device 302. Alternatively, if the docking device 303 is provided with connecting holes, then the scanning object support device 302 is provided with connecting rods, and the number of connecting holes of the docking device 303 is no less than the number of connecting rods of the scanning object support device 302.
[0079] In some embodiments, the length of the connecting hole or connecting rod of the scanning object support device 302 exceeds a predetermined threshold, so as to fix the scanning object support device 302 in the horizontal (i.e., z-axis direction) and vertical (i.e., y-axis direction) directions.
[0080] For example, this threshold can be related to the sum of the weight of the object support 302 and the approximate weight of the object being scanned, and / or to the position of the center of gravity of the entire device when the movable support 3024 reaches its farthest point after being removed from the object support 302. For example, if the weight of the entire device is large and the center of gravity shifts significantly after removal, the connecting rod should be long enough to balance the load.
[0081] For example, the connecting rod can be made of a material with high rigidity and strength. For instance, it can be a metal column, metal rod, or metal tube (steel pipe, iron rod), or it can be a high-strength plastic column, plastic rod, or plastic tube. The cooperation between the connecting rod and the connecting hole generates a large torque, ensuring load balance even after the movable support 3024 is moved out of the scanning object support device 302 and reaches its farthest point.
[0082] Therefore, after the scanning object support device 302 and the docking device 303 have completed docking, when the movable support part 3024 exceeds at least part of the support platform 3021 in the vertical direction, the stability of the scanning object support device 302 can be maintained based on the torque effect, preventing the scanning object support device 302 from overturning or moving.
[0083] The medical imaging system 300 will now be further described from the docking device 303 side.
[0084] Figure 8 This is a schematic diagram of a docking device according to an embodiment of this application. Figure 8 As shown, the docking device 303 includes a body 3031, which is fixed to the ground or the scanning device 301, and has a connecting rod or connecting hole arranged longitudinally along the scanning object support device 302, that is, the body 3031 has a connecting rod or connecting hole arranged along the x-axis direction of the scanning object support device 302. The connecting rod or connecting hole of the docking device 303 can be used in conjunction with the connecting hole or connecting rod of the scanning object support device 302. Figure 8The connecting rod 3032 of the main body 3031 is shown only schematically, and this application is not limited thereto.
[0085] In some embodiments, at least two connecting rods or connecting holes are provided in the transverse direction (i.e., the z-axis direction) of the body portion 3031, or at least two connecting rods or connecting holes are provided in the vertical direction (i.e., the y-axis direction or the direction perpendicular to the ground) of the body portion 3031, or at least two connecting rods or connecting holes are provided in other directions of the body portion 3031, and this application is not limited thereto.
[0086] In some embodiments, if a connecting rod is provided on the main body 3031, a connecting hole is provided on the scanning object support device 302, and the number of connecting rods on the main body 3031 is no more than the number of connecting holes on the scanning object support device 302. If a connecting hole is provided on the main body 3031, a connecting rod is provided on the scanning object support device 302, and the number of connecting holes on the main body 3031 is no less than the number of connecting rods on the scanning object support device 302.
[0087] Therefore, when the scanning object support device 302 moves toward the scanning device 301, the scanning object support device 302 can smoothly dock with the docking device 303 to maintain the stability of the scanning object support device 302 and prevent the scanning object support device 302 from tipping over.
[0088] In some embodiments, the length of the connecting hole or connecting rod of the body portion 3031 exceeds a predetermined threshold to fix the scanning object support device 302 in the horizontal (i.e., z-axis direction) and vertical (i.e., y-axis direction or direction perpendicular to the ground) directions of the body portion 3031.
[0089] Therefore, after the scanning object support device 302 and the docking device 303 have completed docking, when the movable support part 3024 exceeds at least part of the support platform 3021 in the vertical direction, the torque effect brought by the longer connecting rod can prevent the scanning object support device 302 from tipping over, thereby improving the stability of the scanning object support device 302.
[0090] In some embodiments, such as Figure 8 As shown, the connecting rod 3032 of the docking device 303 includes a cylindrical main body and a conical head. This application is not limited to this. For example, the connecting rod 3032 may also be composed of a stepped main body. This application does not limit the material and shape of the connecting rod.
[0091] Therefore, the conical head of the connecting rod 3032 can be conveniently guided into the connecting hole 3061 of the scanning object support device 302, and the main body of the connecting rod 3032 can provide sufficient torque to the scanning object support device 302 to maintain the stability of the scanning object support device.
[0092] In some embodiments, the docking device 303 may also be equipped with a camera 3033, for example, the camera 3033 is located at the front end of the connecting rod or inside the connecting hole, wherein the image acquired by the camera 3033 is displayed on the display unit 308 to guide the movement of the scanning object support device 302.
[0093] For example, the display unit 308 can display a field of view image corresponding to the scanning object support device 302 in real time, which reflects the movement of the scanning object support device 302.
[0094] In some embodiments, the display unit 308 may be disposed on the side of the scanning object support device 302 away from the scanning device 301, i.e., the x2 direction side of the scanning object support device 302, but this application is not limited thereto. Alternatively, the display unit 308 may also be disposed on the scanning device 301. Thus, the operator can manipulate the scanning object support device 302 to dock with the docking device 303 based on the image displayed on the display unit 308, further improving the convenience of operation.
[0095] In some embodiments, the docking device 303 may also be provided with a docking switch 3034, for example, the docking switch 3034 is located on the main body 3031. When the scanning object support device 302 and the scanning device 301 are successfully docked, the docking switch 3034 is triggered.
[0096] For example, after the connecting rod 3032 of the docking device 303 is inserted into the connecting hole 3061 of the scanning object support device 302, the connecting part 306 of the scanning object support device 302 touches the docking switch 3034, and the docking switch 3034 is triggered. After the docking switch 3034 is triggered, the display unit 308 displays "Docking Completed", or "Docking Completed", or other information related to docking completion, which is not limited to this.
[0097] Therefore, after the scanning object support device 302 and the docking device 303 complete docking, the operator can obtain the docking completion information in a timely manner so as to carry out subsequent operations and improve operational efficiency.
[0098] This application also provides a medical imaging system, which includes a scanning device 301, a scanning object support device 302, and a docking device 303.
[0099] Figure 9 This is a schematic diagram of a docking of a medical imaging system according to an embodiment of this application. Figure 9 As shown, the docking device 303 is provided with a connecting rod 3032, and the scanning object support device 302 is provided with a connecting hole 3061. Figure 9(Not shown). When the object support device 302 moves closer to the scanning device 301, that is, when the object support device moves in the x1 direction, the camera 3033 located at the front end of the connecting rod 3032 ( Figure 9 An image is acquired (not shown) and displayed on the display unit 308. Based on the image displayed on the display unit 308, the operator manipulates the scanning object support device 302 to mate with the docking device 303. When the connecting rod 3032 of the docking device 303 is inserted into the connecting hole 3061 of the scanning object support device 302, the scanning object support device 302 triggers the docking switch 3034, and the display unit 308 displays "Docking Complete". The operator can then operate the pressing device 307 by pressing the device 307 (…). Figure 9 (Not shown) is pressed, and the fixing rod 3051 of the fixing part 305 ( Figure 9 (Not shown) Insert into the fixing hole 3052 located on the ground ( Figure 9 (Not shown)
[0100] Therefore, the medical imaging system 300 can fix the scanning object support device 302 based on the torque provided by the connecting rod 3032, restricting the movement of the scanning object support device along the y-axis / z-axis direction, and can restrict the movement of the scanning object support device along the x-axis direction based on the fixing rod 3051. This can improve the stability of the scanning object support device 302 and avoid problems such as the scanning object support platform tilting, which could lead to the inability to complete the scan or even collision with the scanning device.
