Description

Technical Field

[0001] This application relates to the field of medical device control technology, and in particular to a control method for a medical device and a control method for a SPECT-CT scanning device. Background Technology

[0002] With the development of medical technology, medical devices with multiple scanning functions have emerged, allowing multiple types of scanning tests to be completed with a single device. For example, SPECT / CT equipment integrates a CT scanning system and a SPECT scanning system in the same housing, sequentially acquiring CT scan images reflecting fine anatomical structures and SPECT images reflecting functional metabolism. When scanning a patient, medical devices require patient positioning to ensure the patient is in the correct position during the scanning process. In related technologies, laser lights are used only in a single scanning system (such as a CT scanning system) for scanning positioning, resulting in lower scanning efficiency when multiple scans are required. Summary of the Invention

[0003] Therefore, it is necessary to provide a control method for medical devices and a control method for SPECT-CT scanning devices that can improve scanning efficiency, addressing the aforementioned technical problems.

[0004] In a first aspect, this application provides a control method for a medical device. The medical device includes: a first scanning system, a second scanning system, and a scanning bed, wherein the first scanning system and / or the second scanning system are provided with a projection module, the projection module being used to project positioning markers;

[0005] The method includes: responding to a placement command to move the scanning bed to an initial position; wherein, at the initial position, the positioning mark of the object under test on the scanning bed overlaps with the placement mark; controlling the scanning bed to move to a target scanning position based on a movement command; wherein, at the target scanning position, the positioning mark of the object under test on the scanning bed is located at the axial scanning center of the first scanning system or the second scanning system.

[0006] The control method for the aforementioned medical equipment, upon receiving a positioning command, moves the scanning bed to an initial position where the positioning marker of the object under test overlaps with the positioning marker. Then, based on the movement command, the scanning bed is moved to the target scanning position. At the target scanning position, the positioning marker of the object under test on the scanning bed is located at the axial scanning center of the first or second scanning system, and finally, the corresponding scanning steps are performed. This application moves the scanning bed to the initial position in a single positioning operation, and then moves it to the scanning position of the first or second scanning system according to the movement command. This allows the first or second scanning system to complete the corresponding scan in a single positioning operation, improving the overall scanning efficiency of the medical equipment.

[0007] In one embodiment, the step of moving the scanning bed to an initial position in response to a positioning command includes: acquiring a positioning image in response to the positioning command; wherein the positioning image includes images of the positioning marker and the positioning marker; performing image recognition on the positioning image to determine a marker distance; wherein the marker distance is the distance between the positioning marker and the positioning marker; and moving the scanning bed to the initial position based on the marker distance.

[0008] In one embodiment, a target scanning system is determined based on a movement command; wherein the target scanning system is either the first scanning system or the second scanning system; a target movement distance is determined based on the target scanning system; wherein the target movement distance is the axial distance between the axial scanning center of the first scanning system or the second scanning system and the positioning mark; and the scanning bed is moved to the target scanning position based on the target movement distance.

[0009] In one embodiment, the step of moving the scanning bed to the target scanning position based on the target moving distance includes: displaying the remaining time of movement while moving the scanning bed based on the target moving distance.

[0010] In one embodiment, the step of moving the scanning bed to the target scanning position based on the target moving distance includes: controlling the scanning bed to stop moving in response to a movement stop command.

[0011] In one embodiment, after the step of moving the scanning bed to the target scanning position based on the target moving distance, the method further includes: in response to a continue scanning command, moving the scanning bed to a continue scanning position based on a preset moving distance; wherein the preset moving distance is the distance between the axial scanning centers of the first scanning system and the second scanning system, and at the continue scanning position, the positioning marker of the object to be tested on the scanning bed is located at the axial scanning center of the first scanning system or the second scanning system.

[0012] In one embodiment, the method further includes: controlling the projection module to turn on or off in response to a light control command.

[0013] In one embodiment, both the first scanning system and the second scanning system are provided with a projection module, and the method further includes: when the projection module in the first scanning system is turned on, controlling the projection module in the second scanning system to turn off; and when the projection module in the second scanning system is turned on, controlling the projection module in the first scanning system to turn off.

[0014] In one embodiment, the projection module in the first scanning system and / or the second scanning system is disposed outside the scanning aperture, and the positioning mark projected by the projection module is located outside the scanning aperture.

[0015] Secondly, this application also provides a control method for a SPECT-CT scanning device. The scanning device includes a CT scanning system, a SPECT scanning system, and a scanning bed. The CT scanning system and the SPECT scanning system are respectively provided with projection modules, which are used to project positioning marks.

[0016] The method includes: acquiring a scanning protocol; activating a projection module on a corresponding system to display the positioning marker according to the scanning protocol; wherein the positioning marker is located outside the scanning aperture and within the movable range of the scanning bed; moving the scanning bed to an initial position in response to a positioning command; wherein, at the initial position, the positioning marker of the object under test on the scanning bed overlaps with the positioning marker; controlling the scanning bed to translate to a target scanning position based on a movement command and a target movement distance; wherein, at the target scanning position, the positioning marker of the object under test on the scanning bed is located at the axial scanning center of the CT scanning system or the SPECT scanning system.

[0017] The control method of the aforementioned SPECT-CT scanning device, upon acquiring the scanning protocol, activates the projection module on the corresponding scanning system to display the positioning markers. After receiving the positioning command, it moves the scanning bed to an initial position where the positioning markers of the object under test overlap with the positioning markers. Then, based on the movement command, it controls the scanning bed to move to the target scanning position. At the target scanning position, the positioning markers of the object under test on the scanning bed are located at the axial scanning center of the CT or SPECT scanning system. Finally, the corresponding scanning steps are performed. This application moves the scanning bed to the initial position in a single positioning operation, and then moves it to the scanning position of the CT or SPECT scanning system according to the movement command. This allows the CT or SPECT scanning system to complete the corresponding scan in a single positioning operation, improving the overall scanning efficiency of the SPECT-CT scanning device.

[0031] First scanning system 110, second scanning system 120, scanning bed 130, projection module 140, object to be measured 150, axial scanning center 160, placement mark 141, positioning mark 151. Detailed Implementation

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0033] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0034] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. Furthermore, in the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if there is transmission of electrical signals or data between the connected objects.

[0035] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0036] As described in the background section, when multiple scans are required, each scanning system necessitates independent repositioning, leading to low overall scanning efficiency of the medical equipment. For example, with SPECT / CT equipment, only one set of laser lights is located on one side of the CT scanner for CT scan positioning. After the laser lights position the patient's area to be scanned, the medical equipment automatically moves the patient's area to the center of the CT scan, thus completing the CT scan. However, for SPECT scans, staff must manually adjust the patient's position to move the area to the center of the SPECT scan, completing the SPECT scan. This positioning method requires two separate scan setups, resulting in low scanning efficiency when multiple scans are needed.

[0037] Based on this, this application provides a control method for medical equipment and a control method for SPECT-CT scanning device, which can improve the overall scanning efficiency of medical equipment.

[0038] The control method for medical devices provided in this application can be applied to, for example... Figure 1 and Figure 2 The medical device shown includes: a first scanning system 110, a second scanning system 120, and a scanning bed 130. The first scanning system 110 and the second scanning system 120 are two of the following: SPECT (Single Photon Emission Computed Tomography) scanning system, CT (Computed Tomography) scanning system, MRI (Magnetic Resonance Imaging) scanning system, and PET (Positron Emission Tomography) scanning system. Figure 1 and Figure 2 In the first scanning system 110 and the second scanning system 120, a projection module 140 is respectively provided. In some other embodiments, only one projection module 140 may be provided in the first scanning system 110 or the second scanning system 120. The projection module 140 in the first scanning system 110 and / or the second scanning system 120 is located outside the treatment aperture. Correspondingly, the positioning mark 141 projected by the projection module 140 is located outside the treatment aperture. This arrangement can prevent the projection module 140 from affecting the scanning process of the medical device and facilitate the user's observation of the positioning mark 141 projected by the projection module 140.

[0039] The projection module 140 can be composed of multiple projection lamps (such as laser lamps, LED lamps, halogen lamps, etc.), and is used to project the placement markers 141. Figure 1 As shown, the projection modules 140 of both the first scanning system 110 and the second scanning system 120 are used to project the placement markers 141. Figure 2 As shown, the projection module of the first scanning system 110 is turned off, and the positioning mark 141 is projected only through the projection module 140 of the second scanning system 120. Figure 3 As shown, under normal circumstances, the positioning marks 141 projected by the projection module 140 onto the object under test 150 are orthogonal line segments, and the projection module 140 can project corresponding positioning marks 141 onto different sides of the object under test 150 (such as coronal plane, sagittal plane, cross-section, etc.). It can be understood that the positioning marks 141 projected by the projection module 140 can also be other shapes, such as X-shaped shapes, rectangles, triangles, or other irregular shapes, as long as they can be used for positioning.

[0040] The scanning bed 130 is used to carry the object to be tested 150. The scanning bed 130 can move within the scanning apertures of the first scanning system 110 and the second scanning system 120 to complete the scanning of the area to be tested on the object 150. The scanning bed 130 may have only one degree of freedom of movement, or it may have three degrees of freedom (up and down, left and right, forward and backward) or more of movement capabilities, which can be set according to the specific scanning needs of the medical device. When it has only one degree of freedom of movement capability, moving the scanning bed 130 only requires translating the scanning bed 130. In this embodiment of the medical device, when performing a scan, a positioning mark 151 is also added to the area to be tested on the object 150. The positioning mark 151 is used to indicate the area to be scanned. The positioning mark 151 can be a surface mark drawn with a marker or a sticker, etc., which can be selected as needed. In this embodiment of the application, a cross-shaped positioning mark 151 is used as an example for explanation.

[0041] In one embodiment, such as Figure 4 As shown, a control method for a medical device is provided, which is applied to... Figure 2 Taking medical devices as an example, the explanation includes the following steps:

[0042] Step S210: In response to the positioning command, the scanning bed is moved to the initial position.

[0043] Specifically, users can send positioning commands to the medical device through the user interface. Upon receiving the positioning command, the medical device will control the scanning bed 130 to move to its initial position. For example... Figure 5As shown, when the scanning bed 130 is in its initial position, the positioning mark 151 of the object to be tested 150 on the scanning bed 130 overlaps with the placement mark 141, thereby completing the placement of the object to be tested 150. It is understandable that, based on different placement principles of medical devices, placement commands can have different meanings. For example, if the medical device requires manual adjustment of the scanning bed 130 to achieve placement, the placement command can be used only to adjust the position of the scanning bed 130; if the medical device can automatically adjust the position of the scanning bed 130 to achieve placement, the placement command can be used to instruct the medical device to begin executing the automatic placement procedure.

[0044] Step S220: Based on the movement command, control the scanning bed to move to the target scanning position.

[0045] Specifically, the user can send movement commands to the medical device through the user interface. These commands instruct the scanning bed 130 to move to either the first scanning system 110 or the second scanning system 120. Once the medical device determines that the scanning bed 130 has reached its initial position, it will control the scanning bed 130 to move to the target scanning position according to the movement commands. At the target scanning position, the positioning marker 151 of the object 150 on the scanning bed 130 is located at the axial scanning center 160 of either the first scanning system 110 or the second scanning system 120. Figure 6 As shown, the movement command instructs the scanning bed 130 to move to the first scanning system 110 for scanning. Therefore, the medical device controls the scanning bed 130 to move to the corresponding position, where the positioning mark 151 of the object under test 150 is located at the axial scanning center 160 of the first scanning system 110. Figure 7 As shown, the movement command instructs the scanning bed 130 to move to the second scanning system 120 for scanning. Therefore, the medical device controls the scanning bed 130 to move to the corresponding position, where the positioning mark 151 of the object under test 150 is located at the axial scanning center 160 of the second scanning system 120. After the medical device controls the scanning bed 130 to move to the target scanning position based on the movement command, the medical device will continue to execute the corresponding scanning procedure, thereby completing the corresponding scan of the object under test 150. It can be understood that after the object under test 150 is scanned by the first scanning system 110 or the second scanning system 120, the medical device can also control the scanning bed 130 to move the object under test 150 to another scanning system for another type of scan.

[0046] The control method for the aforementioned medical equipment, upon receiving a positioning command, moves the scanning bed 130 to an initial position where the positioning mark 151 of the object under test 150 overlaps with the positioning mark 141. Then, based on the movement command, the scanning bed 130 is moved to the target scanning position. At the target scanning position, the positioning mark 151 of the object under test 150 on the scanning bed 130 is located at the axial scanning center 160 of the first scanning system 110 or the second scanning system 120, and finally, the corresponding scanning steps are performed. This application moves the scanning bed 130 to the initial position in a single positioning operation, and then moves it to the scanning position of the first scanning system 110 or the second scanning system 120 according to the movement command. This allows the first scanning system 110 or the second scanning system 120 to complete the corresponding scan in a single positioning operation, improving the overall scanning efficiency of the medical equipment.

[0047] In one embodiment, such as Figure 8 As shown, step S210, the step of moving the scanning bed to the initial position in response to the positioning command, includes:

[0048] Step S211: In response to the positioning command, acquire the positioning image.

[0049] Specifically, the medical device in this embodiment can automatically perform positioning. After receiving a positioning command, the medical device begins to execute the corresponding positioning procedure. The medical device first activates the camera and uses the camera to acquire images, including the positioning marker 151 and the positioning marker 141, in real time, and uses these images as the positioning images. It is understood that the image acquisition range of the camera is generally large. When the object under test 150 moves onto the scanning bed 130, the positioning marker 151 on the object under test 150 and the positioning marker 141 projected by the projection module 140 are generally within the image acquisition range of the camera.

[0050] Step S212: Perform image recognition on the placement image to determine the marker distance.

[0051] Specifically, after acquiring the positioning image, the medical device uses a preset image processing algorithm to identify the positions of positioning marker 151 and positioning marker 141 from the positioning image through steps such as edge detection and shape recognition. Then, it calculates the distance between positioning marker 151 and positioning marker 141 to obtain the marker distance. The marker distance can be the actual distance between positioning marker 151 and positioning marker 141 after processing, or it can be the image distance between positioning marker 151 and positioning marker 141 in the positioning image.

[0052] Step S213: Move the scanning bed to the initial position based on the marked distance.

[0053] Specifically, after the medical equipment determines the marked distance, it can determine the direction and distance the scanning bed 130 needs to move based on the sign and magnitude of the marked distance. The medical equipment then controls the movement of the scanning bed 130 accordingly based on these parameters, thus moving the scanning bed 130 to its initial position. It is understood that there is a direct proportional relationship between the marked distance and the distance the scanning bed 130 needs to move; the specific value can be determined through prior testing.

[0054] In some other embodiments, the positioning command is only used to adjust the position of the scanning bed 130. During the positioning process, the user manually adjusts the position of the scanning bed 130 by observing the positional relationship between the positioning mark 151 and the positioning mark 141 until the positioning mark 151 of the object to be tested 150 is aligned with the positioning mark 141, thus completing the manual positioning. It is understood that the medical device can have both automatic and manual positioning functions, and the user can choose according to specific needs.

[0055] In one embodiment, such as Figure 9 As shown, step S220, the step of controlling the scanning bed to move to the target scanning position based on the movement command, includes:

[0056] Step S221: Determine the target scanning system based on the movement command.

[0057] Specifically, in this embodiment, when the medical device controls the scanning bed 130 to move to the target scanning position based on the movement command, it first determines whether the target scanning system that needs to perform the scanning task is the first scanning system 110 or the second scanning system 120 according to the movement command.

[0058] Step S222: Determine the target movement distance based on the target scanning system.

[0059] Specifically, after the medical device identifies the target scanning system, it determines the corresponding target movement distance based on the type of the target scanning system. The target movement distance is the axial distance between the axial scanning center 160 of the first scanning system 110 or the second scanning system 120 and the positioning marker 141. It can be understood that the relative position between the projection module 140 and the first scanning system 110 and the second scanning system 120 is fixed. Therefore, the relative position between the positioning marker 141 after vertical projection from the projection module 140 and the first scanning system 110 and the second scanning system 120 is also fixed. The corresponding target movement distance can be predetermined and stored in the medical device, and can be directly retrieved after the target scanning system is identified. A specific example is shown below. Figure 6As shown, the target scanning system determined based on the movement command is the first scanning system 110. At this time, the corresponding target movement distance is the axial distance between the axial scanning center 160 of the first scanning system 110 and the positioning mark 141, which is A in the figure. Figure 7 As shown, the target scanning system determined based on the movement command is the second scanning system 120. In this case, the corresponding target movement distance is the axial distance between the axial scanning center 160 of the second scanning system 120 and the positioning mark 141, which is B in the figure. It can be understood that... Figure 6 and Figure 7 The diagram shows the target movement distance when the projection module 140 is set in the second scanning system 120 and projects the positioning mark 141. The target movement distance when the projection module 140 is set in the first scanning system 110 and projects the positioning mark 141 is similar, and will not be described again here.

[0060] Step S223: Move the scanning bed to the target scanning position based on the target moving distance.

[0061] Specifically, after determining the target movement distance, the medical device controls the scanning bed 130 to move the corresponding distance. Once the scanning bed 130 stops moving, it will be positioned at the target scanning location. The medical device then executes the corresponding scanning program to scan the object 150.

[0062] In one embodiment, step S223, the step of moving the scanning bed to the target scanning position based on the target moving distance, includes: displaying the remaining time of movement when moving the scanning bed based on the target moving distance.

[0063] Specifically, in this embodiment, to improve user experience and operational transparency, the medical device can display the remaining movement time in real time as the scanning bed 130 moves based on the target moving distance. The remaining movement time can be calculated in real time based on the target moving distance and the current moving speed, or pre-stored in the medical device if the moving speed of the scanning bed 130 is fixed. The medical device can display the remaining movement time through an area set on the user interface (such as a console, touchscreen, or monitor), updating the remaining movement time in real time during the movement of the scanning bed 130 until the scanning bed 130 reaches the target scanning position and stops moving.

[0064] In one embodiment, step S223, the step of moving the scanning bed to the target scanning position based on the target moving distance, includes: controlling the scanning bed to stop moving in response to a movement stop command.

[0065] Specifically, in this embodiment, to improve the flexibility and safety of the medical device, when the medical device moves the scanning bed 130 based on the target moving distance, it needs to monitor the movement stop command from the control system or user interface in real time. Upon receiving the movement stop command, the medical device will control the scanning bed 130 to stop moving. The medical device can monitor itself in real time for malfunctions (such as motor overheating, sensor failure, etc.) through the control system and generate a corresponding movement stop command if a malfunction is detected. The medical device can also obtain movement stop commands triggered by the user through the user interface, such as displaying a stop button in the user interface and responding to the user's touch action.

[0066] In one embodiment, after step S223, which involves moving the scanning bed to the target scanning position based on the target moving distance, the control method of the medical device further includes: responding to a continue scanning command by moving the scanning bed to the continue scanning position based on a preset moving distance.

[0067] Specifically, after the scanning bed 130 moves to the target scanning position, the medical device executes the corresponding scanning program to complete the scanning of the object to be tested 150. After the scan is completed, the user can send a continue scanning command to the medical device through the user interface. This command instructs the medical device to continue scanning using another scanning system. Upon receiving the continue scanning command, the medical device moves the scanning bed 130 to the continue scanning position based on a preset distance. This preset distance is the distance between the axial scanning centers 160 of the first scanning system 110 and the second scanning system 120. At the continue scanning position, the positioning marker 151 of the object to be tested 150 on the scanning bed 130 is located at the axial scanning center 160 of either the first scanning system 110 or the second scanning system 120. For a specific example, see... Figure 6 As shown, the target scanning system determined based on the movement command is the first scanning system 110. After the first scanning system 110 completes the scanning of the object to be tested 150, upon receiving the continue scanning command from the medical device, the medical device will determine the target scanning system based on the distance between the axial scanning centers 160 of the first scanning system 110 and the second scanning system 120, i.e. Figure 7 The scanning bed 130 is moved by a distance C to move it to a continuing scanning position. In the continuing scanning position, the positioning mark 151 of the object to be tested 150 on the scanning bed 130 is located at the axial scanning center 160 of the second scanning system 120.

[0068] In one embodiment, the control method for the medical device further includes: controlling the projection module to turn on or off in response to a light control command.

[0069] Specifically, in this embodiment, the medical device can obtain corresponding lighting control commands through the user interface and control the projection module 140 to turn on or off according to the lighting control commands. It can be understood that when both the first scanning system 110 and the second scanning system 120 are equipped with projection modules 140, the lighting control commands can control the projection modules 140 in the two systems to turn on or off respectively.

[0070] In one embodiment, both the first scanning system 110 and the second scanning system 120 of the medical device are equipped with projection modules 140. To prevent the projection modules 140 in both systems from simultaneously illuminating the eye area of ​​the subject 150, the control method of the medical device further includes: controlling the projection module 140 in the second scanning system 120 to close when the projection module 140 in the first scanning system 110 is open; and controlling the projection module 140 in the first scanning system 110 to close when the projection module 140 in the second scanning system 120 is open. That is, at any given time, only one of the projection modules 140 in the two systems can be open, and they cannot be open simultaneously.

[0071] In one embodiment, if the medical device is not operated within a preset time after the projection module 140 is turned on, the projection module 140 is controlled to turn off to prevent damage to the device caused by the user forgetting to turn off the projection module 140.

[0072] In one embodiment, such as Figure 10 As shown, this application also proposes a control method for a SPECT-CT scanning device. The scanning device includes a CT scanning system, a SPECT scanning system, and a scanning bed 130. Projection modules 140 are respectively provided in the CT scanning system and the SPECT scanning system. The projection modules 140 are used to project positioning markers 141. The control method for the SPECT-CT scanning device includes the following steps:

[0073] S310, obtain the scanning protocol.

[0074] Specifically, users can input the corresponding scanning protocol into the SPECT-CT scanning device through the user interface. The scanning protocol is used to indicate to the SPECT-CT scanning device that it needs to perform SPECT scanning and / or CT scanning.

[0075] S320, according to the scanning protocol, activates the projection module on the corresponding system to display the placement markings.

[0076] Specifically, after acquiring the scanning protocol, the SPECT-CT scanning device parses the protocol to determine the required scanning operation. It then activates the projection module 140 on either the CT or SPECT scanning system, projecting and displaying a positioning marker 141. This positioning marker 141 is located outside the scanning aperture and within the movable range of the scanning bed 130, ensuring easy visibility for the user. It is understood that the projection module 140 on the CT and SPECT scanning systems can be configured to operate only once. When both the SPECT and CT scanning systems need to perform scans, the projection module 140 of the system requiring the first scan can be activated according to the scanning sequence.

[0077] S330, responding to a positioning command, moves the scanning bed to its initial position.

[0078] Specifically, users can send positioning commands to the SPECT-CT scanning device through the user interface. Upon receiving the positioning command, the SPECT-CT scanning device will control the scanning bed 130 to move to its initial position. For example... Figure 5 As shown, when the scanning bed 130 is in its initial position, the positioning mark 151 of the object to be tested 150 on the scanning bed 130 overlaps with the placement mark 141, thereby completing the placement of the object to be tested 150. It is understandable that, based on different placement principles of the SPECT-CT scanning device, the placement command can have different meanings. For example, if the SPECT-CT scanning device requires manual adjustment of the scanning bed 130 to achieve placement, the placement command can be used only to adjust the position of the scanning bed 130; if the medical device can automatically adjust the position of the scanning bed 130 to achieve placement, the placement command can be used to instruct the SPECT-CT scanning device to begin executing the automatic placement procedure.

[0079] S340 controls the scanning bed to translate to the target scanning position based on the movement command and the target movement distance.

[0080] Specifically, in this embodiment, when the SPECT-CT scanning device controls the scanning bed 130 to move to the target scanning position based on the movement command and the target movement distance, it first determines whether the target scanning system to be scanned is a CT scanning system or a SPECT scanning system based on the movement command. After determining the target scanning system, the corresponding target movement distance is determined according to the specific type of the target scanning system. The target movement distance is the axial distance between the axial scanning center 160 of the CT scanning system or the SPECT scanning system and the positioning marker 141. It can be understood that the relative position between the projection module 140 and the CT scanning system and the SPECT scanning system is fixed. Therefore, the relative position between the positioning marker 141 after vertical projection of the projection module 140 and the CT scanning system and the SPECT scanning system is also fixed. The corresponding target movement distance can be predetermined and stored in the SPECT-CT scanning device, and can be directly called after the target scanning system is determined. After determining the target movement distance, the SPECT-CT scanning device controls the scanning bed 130 to move the corresponding distance. Once the scanning bed 130 stops moving, it will be positioned at the target scanning location. At this location, the positioning marker 151 of the object 150 on the scanning bed 130 is located at the axial scanning center 160 of the CT or SPECT scanning system. The SPECT-CT scanning device then executes the corresponding scanning program to scan the object 150.

[0081] It is understood that the solution provided by the control method of the SPECT-CT scanning device in the embodiments of this application is similar to the solution described in the control method of the medical device described above. Therefore, the specific limitations in the embodiments of the control method of the SPECT-CT scanning device can be found in the limitations of the control method of the medical device described above, and will not be repeated here.

[0082] The control method of the SPECT-CT scanning device of this application is described in detail below with a specific embodiment. The user sets corresponding positioning marks 151 on the object 150 according to the parts to be scanned, and simultaneously inputs the corresponding scanning protocol into the SPECT-CT scanning device. The following description assumes that the object 150 only needs to undergo a SPECT scan. After obtaining the scanning protocol, the SPECT-CT scanning device determines that the object 150 needs to undergo a SPECT scan. Therefore, it only turns on the projection module 140 on the SPECT scanning system, while keeping the projection module 140 on the CT scanning system closed. The projection module 140 on the SPECT scanning system projects the positioning marks 141, which are then displayed on the object 150. After receiving the positioning command, the SPECT-CT scanning device begins to move the position of the scanning bed 130 according to the movement command and the target movement distance until the positioning marks 151 of the object 150 overlap with the positioning marks 141. Before moving the scanning bed 130 to its designated position, the SPECT-CT scanner can prompt the user to confirm the safety of the surrounding environment and the condition of the object under test 150. The scanner will only begin moving the scanning bed 130 after the user inputs a confirmation command. While moving the scanning bed 130 based on the target moving distance, the SPECT-CT scanner can display the remaining moving time in real time and control the scanning bed 130 to stop moving upon receiving a stop command. Once the scanning bed 130 has moved to the target scanning position, the positioning marker 151 of the object under test 150 is located at the axial scanning center 160 of the SPECT scanning system, and the SPECT scanning system will begin performing the SPECT scan to obtain the corresponding SPECT image. After the SPECT scanning system finishes scanning, the user can also input a continue scanning command to the SPECT-CT scanner. Upon receiving the continue scanning command, the SPECT-CT scanner will move the scanning bed 130 to the continue scanning position based on a preset moving distance. When the positioning mark 151 of the object to be tested 150 on the scanning bed 130 is located at the axial scanning center 160 of the CT scanning system, the CT scanning system will start CT scanning to obtain the corresponding CT image.
