[0002] With the development of medical imaging technology, medical imaging scanning is being used more and more widely in clinical practice.

[0003] In related technologies, before performing image scanning, technicians need to step on a control device placed next to the patient support platform to control the movement of the patient support platform, thereby adjusting the patient's position.

[0004] However, the control devices next to the patient support platform are easily stepped on by patients, which could lead to safety accidents. Summary of the Invention

[0006] In a first aspect, this application provides a control method for a control device for controlling a patient support platform, comprising:

[0007] Determine whether the target personnel's operation of the equipment meets the preset conditions;

[0008] When the preset conditions are met, the system responds to the trigger signals generated by the target personnel through the operation of the control equipment, and controls the patient support platform.

[0009] In one embodiment, prior to responding to a trigger signal generated by a target person operating the control device, the process includes:

[0010] Determine whether the control device switch used to control the control device is in the enabled state;

[0018] The target person's single stepping time on the foot pedal device reaches the preset duration;

[0019] The target person's single step on the foot pedal device falls within the preset range; and

[0020] Whether the target personnel step on the foot pedal device within the preset time period.

[0021] In one embodiment, the control device is covered by a movable cover, and / or the control device is a kick-triggered foot pedal device.

[0022] In one embodiment, the target person is verified to have control over the control device.

[0023] In one embodiment, it further includes:

[0024] In response to the start command of the control device, detect whether there are personnel within a preset range around the control device;

[0025] If people are present, their facial information will be collected.

[0026] Verify whether a person is the target person based on their facial information.

[0027] In one embodiment, it further includes:

[0031] The determination module is used to determine whether the target personnel's operation of the control equipment meets the preset conditions;

[0032] The control module is used to control the patient support platform in response to trigger signals generated by the target personnel through the operation of the control device when the operation meets the preset conditions.

[0033] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement any embodiment of the control method for controlling the manipulator of the patient support platform described in the first aspect above.

[0035] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, implements any embodiment of the control method for controlling the manipulator of the patient support platform described in the first aspect above.

[0036] The aforementioned control method and apparatus for controlling the control device of a patient support platform determines whether the operation of the control device by the target person meets preset conditions. If the operation meets the preset conditions, the method responds to a trigger signal generated by the target person operating the foot pedal device to control the patient support platform. By matching the target person's operation with preset conditions, and ensuring that the target person can generate trigger information by operating the control device to control the movement of the patient support platform when the preset conditions are met, this method can prevent patients from accidentally stepping on the control device next to the patient support platform, thus preventing safety accidents.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] The control method for controlling the manipulator of a patient support platform provided in this application embodiment can be applied to, for example... Figure 1The application environment shown includes a medical device 10 and a computer device 11. The medical device 10 includes a control device 101 and a patient support platform 102. The control device 101 is located below the patient support platform 102. A movable cover 103 (e.g., a spring cover) can be provided around the control device 101. The cover 103 can cover or shield the control device 101 from all directions or at least cover the control triggering part. Alternatively, the cover 103 may not be provided around the control device 101, and the control device 101 can be triggered to open by a trigger signal. The medical device may be a computed tomography (CT) scanner, magnetic resonance imaging (MRI), positron emission tomography (PET), functional magnetic resonance imaging (fMRI), single-photon emission computed tomography (SPECT), etc.

[0056] In one exemplary embodiment, such as Figure 2 As shown, a control method for a manipulator device used to control a patient support platform is provided, which is then applied to... Figure 1 The following steps, 101 to 102, are used as an example of computer equipment in the example. Wherein:

[0057] S101, determine whether the target personnel's operation of the control equipment meets the preset conditions.

[0058] The control device can be a foot pedal device, a hand pressing device, etc.

[0059] In this embodiment, when the control device is a foot pedal device, the target person can pedal the foot pedal device multiple times, and determine whether the number of pedaling operations exceeds a preset threshold. Based on the determination result, it is determined whether the operation of the control device meets the preset conditions. Alternatively, the target person can increase the pedaling force, and determine whether the pedaling force exceeds a preset force threshold. Based on the determination result, it is determined whether the operation of the control device meets the preset conditions. Or, the target person can continuously pedal the foot pedal device, and determine whether the continuous pedaling time exceeds a preset time threshold. Based on the determination result, it is determined whether the operation of the control device meets the preset conditions.

[0060] Similarly, when the control device is a palm-press device, the user can press the palm-press device multiple times and determine if the number of presses exceeds a preset threshold. Based on the result, it is determined whether the operation of the control device meets the preset conditions. Alternatively, the user can increase the pressing force and determine if the pressing force exceeds a preset force threshold. Based on the result, it is determined whether the operation of the control device meets the preset conditions. Alternatively, the user can continuously press a foot pedal device and determine if the duration of continuous pressing exceeds a preset time threshold. Based on the result, it is determined whether the operation of the control device meets the preset conditions.

[0061] S102, when the preset conditions are met, responds to the trigger signal generated by the target personnel through the operation of the control device and controls the patient support platform.

[0062] In this embodiment, when it is determined that the target person's operation of the operating device meets preset conditions, the operating device is determined to be in a controllable state. In this case, the target person can operate the operating device by stepping on it or pressing it with their palm to generate a trigger signal, and control the movement of the patient support platform based on the trigger signal. If the patient support platform is a scanning bed, then operating the operating device can realize the movement of the scanning bed.

[0063] The aforementioned control method and apparatus for controlling the control device of a patient support platform determines whether the operation of the control device by the target person meets preset conditions. If the operation meets the preset conditions, the method responds to a trigger signal generated by the target person operating the foot pedal device to control the patient support platform. By matching the target person's operation with preset conditions, and ensuring that the target person can generate trigger information by operating the control device to control the movement of the patient support platform when the preset conditions are met, this method can prevent patients from accidentally stepping on the control device next to the patient support platform, thus preventing safety accidents.

[0064] In one embodiment, such as Figure 3 As shown, before responding to a trigger signal generated by a target person operating the control device, the method includes:

[0065] S201, determine whether the control device switch used to control the control device is in the enabled state.

[0066] The control switch of the control device can be a push-button switch, a power supply switch, or any other type of switch. The control switch can be located on the patient support platform, for example, on the console or housing of the patient support platform. However, it is not limited to this; for example, the control switch can also be located outside the patient support platform, such as on a separate remote control or other remote control device, or in specific computer or mobile application software (e.g., as an icon on the application software user interface, such as a virtual button or lever). Generally, the control switch of the control device is configured to be off by default.

[0067] Taking a foot pedal control device and its switch as an example, to prevent accidental activation of the foot pedal by personnel other than the target user before scanning, the foot pedal can be set to always be powered on while the switch is off. Therefore, even if accidental activation occurs while the switch is off, the scanning bed cannot be controlled. However, this is not the only option; both the foot pedal and its switch can be set to off, and the foot pedal can only be powered on after the user enables the switch.

[0068] In this embodiment of the application, as an example, if the foot pedal switch of the foot pedal device is a push button switch, the computer device can obtain the switch state of the push button switch. If the push button switch is in the on state, it means that the foot pedal switch is in the enabled state; if the push button switch is not in the on state, it means that the foot pedal switch is not in the enabled state.

[0069] As another example, if the foot pedal switch of the foot pedal device is the power supply switch of the foot pedal device, the computer device can obtain the power supply status of the foot pedal device. If the foot pedal device is in a powered state, it means that the foot pedal switch is also in an enabled state; if the foot pedal device is not in a powered state, it means that the foot pedal switch is not in an enabled state.

[0070] S202, if it is determined that the control device switch is in the enabled state, a trigger signal is detected.

[0071] In this embodiment, the control device switch is in an enabled state, indicating that the control device is powered on. In this case, if a target person generates a trigger signal on the control device, the target person can operate the control device to control the movement of the patient support platform. As a non-limiting example, specifically, the computer device can acquire the number of times the target person operates the control device, or the force of a single operation, or the duration of a single operation, or the range of a single operation, or the duration of the operation, and use the acquired signals as trigger signals.

[0072] In the aforementioned control method for the control device used to control the patient support platform, it is determined whether the control device switch is in an enabled state; if the control device switch is determined to be in an enabled state, a trigger signal is detected. By setting a control device switch for the control device, and based on whether the control device switch is in an enabled state, it is determined whether the control device can be used normally. Furthermore, if the control device switch is in an enabled state, the trigger signal generated by the target person's operation is detected. From the perspectives of setting the control device switch and detecting the trigger signal, only when both conditions are met can the movement of the scanning bed be controlled by the control device. This avoids the control device next to the patient support platform being accidentally stepped on by the patient, preventing safety accidents. In addition, powering on the control device when the control device switch is on saves power consumption.

[0073] Furthermore, after detecting a trigger signal generated by the target personnel operating the control device, it is necessary to determine whether the trigger signal meets the enabling conditions. Only when the conditions are met can the target personnel control the movement of the patient support platform through the control device. In one embodiment, such as... Figure 4 As shown, the above method also includes:

[0074] S301, determine whether the operation meets the preset control enable conditions.

[0075] In one embodiment, the control device is a foot pedal device, and the control enabling conditions include one or more of the following: the target person steps on the foot pedal device a preset number of times; the target person steps on the foot pedal device with a preset force value; the target person steps on the foot pedal device for a preset duration; the target person steps on the foot pedal device within a preset range; and the target person steps on the foot pedal device for a preset time period.

[0076] In this embodiment, taking a foot pedal device as an example, when the trigger signal is the number of times the target person steps on the pedal, the computer device can compare the number of times the target person steps on the pedal with a preset number. If the number of steps is the same as the preset number, it is determined that the number of steps by the target person satisfies the preset control enable condition. When the trigger signal is the force of a single step, the computer device can compare the force of the target person's single step on the foot pedal with a preset force value. If the force of the target person's step on the foot pedal reaches the preset force value each time, it is determined that the force of the target person's step meets the preset control enable condition. When the trigger signal is the duration of a single step, the computer device can compare the duration of the target person's single step on the foot pedal with a preset duration. If the duration of the target person's step on the foot pedal reaches the preset duration each time, it is determined that the duration of the target person's step meets the preset control enable condition. When the trigger signal is the range of a single step on the foot pedal, the computer device compares the range of the target person's single step with a preset range. If the target person's step range is within the preset range each time, it is determined that the target person's step range meets the preset control enable condition. When the trigger signal is the time the target person steps on the foot pedal, the computer device can determine whether the target person's stepping time falls within a preset time period. If the stepping time falls within the preset time period, it is determined that the target person's stepping time meets the preset control enable condition. For example, the preset time period could be from 9:00 AM to 5:00 PM.

[0077] If the trigger signal consists of any two or more signals, the trigger signal will only meet the preset enable condition if both of these signals satisfy their corresponding preset conditions. For example, the trigger signal will only meet the preset control enable condition if the number of times the pedal is stepped on reaches a preset number and the force of each step reaches a preset force value.

[0078] It should be noted that if the force, duration, or range of any stepping on the foot pedal by the target person does not meet the preset conditions, it means that the trigger signal of the target person does not meet the preset control enable conditions.

[0079] S302, when the trigger signal meets the control enable conditions, generates a control signal for controlling the patient support platform.

[0080] In this embodiment of the application, when it is determined that the trigger signal meets the preset control enable conditions, it means that the target person has triggered a trigger signal that meets the control enable conditions. At this time, the target person can generate a control signal to control the patient support platform by stepping on the foot pedal device.

[0081] Taking the patient support platform as an example, when the user is on the scanning bed and the scanning bed is being moved, the user can press on the foot pedal to generate a control signal that causes the scanning bed to move. This control signal can then be used to control the movement of the scanning bed associated with the foot pedal.

[0082] In one embodiment, the specific process of moving the scanning bed is described as follows:

[0083] Control signals are generated based on the foot pedal movements of the target personnel on the foot pedal device; these control signals are used to control the movement of the scanning bed to which the foot pedal device belongs.

[0084] The scanning bed can move in different directions during its movement. Each direction corresponds to a foot pedal device. For example, moving the scanning bed to the left requires stepping on foot pedal 1, and moving it to the right requires stepping on foot pedal 2. The user can determine the direction the scanning bed needs to move based on the actual scanning scenario and step on the corresponding foot pedal. After receiving the user's stepping action on the foot pedal, the computer equipment can generate a control signal to control the scanning bed to move in the direction corresponding to that foot pedal.

[0085] It should be noted that the angle of movement of the foot pedal device can be fixed with each step. For example, the scanning bed moves by 5° each time the target person steps on the foot pedal device.

[0086] In the control method described above for controlling the manipulator of the patient support platform, a control signal is generated based on the foot pedal action of the target person on the foot pedal device; the control signal is used to control the movement of the scanning bed to which the foot pedal device belongs. This method controls the movement of the scanning bed based on the foot pedal action of the target person, avoiding safety accidents caused by accidental movement of the scanning bed due to accidental stepping, and improving the safety of the scanning process.

[0087] In the aforementioned control method for the control device of the patient support platform, it is determined whether the trigger signal meets the preset control enable condition; if the trigger signal meets the control enable condition, a control signal for controlling the patient support platform is generated. This method uses the control enable condition as a constraint, and by judging the trigger signal from the target person on the control device, it can accurately determine whether the patient support platform can be controlled after the trigger signal is triggered. Furthermore, by judging the trigger signal, it can prevent patients from accidentally stepping on the control device next to the patient support platform, thus preventing safety accidents.

[0088] By identifying the control device's switch and trigger signal angle, accidental stepping on the control device can be avoided to some extent. Furthermore, a protective shell can be installed around the control device, preventing personnel other than the target user from operating it through the shell. In one embodiment, the control device is covered by a movable cover, and / or the control device is a kick-triggered foot pedal device.

[0089] The cover is used to protect the control equipment; let's take a foot-operated control device as an example again. Figure 5 This is a schematic diagram of the cover plate. As can be seen from the diagram, the foot pedal device is located inside the cover plate. When the user needs to control the movement of the scanning bed via the foot pedal device, they can open the cover plate on the foot pedal device through a preset action. The preset action of the user can be various pre-set actions, such as stepping on a preset position of the cover plate, pressing the start button on the cover plate, or opening the cover plate by lifting the toes, etc. When the user performs the preset action, the cover plate will open automatically. A kick-triggered foot pedal device means that the scanning bed can be moved while the user is continuously pressing the foot pedal device. When the user leaves the foot pedal device, the scanning bed cannot be moved, thus avoiding accidental activation by the patient.

[0090] Figure 6 , Figure 7 , Figure 8 These are all schematic diagrams of the preset actions of the target personnel. Figure 6 The target personnel hooked the cover plate by lifting their toes. Figure 7 The target personnel continued to lift the cover plate to a certain height by using their toes. Figure 8 Once the cover plate rises to a preset height and remains at that height, the target personnel can step on the foot pedal inside the cover plate to control the movement of the scanning bed.

[0091] It is understood that the aforementioned cover plate can be a mechanical cover plate, see reference. Figures 6 to 8 The cover is opened by the user lifting their foot. Alternatively, the cover can be electrically operated, opened under specific circumstances or automatically when a specific action by the foot is detected. For example, holding the foot still on the cover for a specific duration, or sliding the foot back and forth on the pedal a specific number of times.

[0092] In the control method described above for controlling the manipulator of the patient support platform, the manipulator is covered by a movable cover, and / or the manipulator is a kick-triggered foot pedal device. This method provides comprehensive protection for the manipulator through physical isolation using the cover, thus further addressing the issue of accidental stepping and improving safety.

[0093] The above embodiment prevents patients from accidentally stepping on the control device next to the patient support platform by considering both the control device switch and the control enable condition. Furthermore, if it is determined that the control device switch is enabled and the target person has not generated a trigger signal by operating the control device, the personnel around the control device can be identified to determine if they are the target person. The target person is verified to have control authority over the control device.

[0094] Verification of the target person can occur before, during, or after the control device is turned on. As a non-limiting example of verification occurring before the control device is turned on, the person's identity can be confirmed by scanning them with a camera installed on the patient support platform when they enter the area where the control device is located or approach it, or by having them enter a password or swipe an authentication card on the patient support platform. As a non-limiting example of verification occurring during or after the control device is turned on, verification can be performed by checking the person's fingerprint or facial recognition when they press a button on the patient support platform or its remote control device, or by clicking an icon on the user interface of the patient support platform or its remote control device.

[0095] The following example illustrates how to detect the presence of a target person within a preset range around the control device. Figure 9 As shown, the specific content includes the following steps:

[0096] S401, in response to the start command of the control device, detects whether there are personnel within a preset range around the control device.

[0097] The control device start command can be a command generated when the medical device corresponding to the patient support platform is powered on, or a command generated when the target personnel need to move the patient support platform.

[0098] Before a user is scanned using medical equipment, they need to lie on the patient support platform of the equipment. Continuing with the example of the scanning bed as the patient support platform and the foot pedals as the control device, the foot pedals controlling the movement of the scanning bed are typically located beneath it. Therefore, when a user or an accompanying user approaches the scanning bed, they may accidentally step on the foot pedals, causing the scanning bed to move and potentially leading to a safety accident. To prevent such accidents, the person using the foot pedals is identified. Only those with control over the foot pedals are designated as the target personnel, and these individuals can control the movement of the scanning bed by stepping on the foot pedals.

[0099] In this embodiment, upon receiving a start command for the control device, the computer device can acquire images within the scanning range using a camera on the patient support platform, and analyze these images using a target detection model to determine whether any personnel are present within a preset range around the control device. Alternatively, the computer device can use a detector to scan the preset range around the control device to determine whether any personnel are present within that range. This embodiment does not limit the method used to detect whether personnel are present within the preset range around the control device.

[0100] S402, if personnel are present, collect their facial information.

[0101] In this embodiment of the application, when it is determined that there are people within a preset range around the control device, the computer device can use the camera device on the patient support platform to collect images within the preset range around the control device, and analyze the images through a person detection algorithm to determine the person's facial information.

[0102] S403: Verify whether a person is the target person based on their facial information.

[0103] In this embodiment, the computer device can match a person's facial information with pre-stored facial information in an information database. If the match is successful, it indicates that the person within a preset range around the control device is the target person; if the match is unsuccessful, it indicates that the person within the preset range around the control device is not the target person. Further, if the preset range around the control device includes multiple people, the facial information of the person closest to the control device is matched with pre-stored facial information in the information database. Based on the matching result, it is determined whether a target person exists within the preset range around the control device. Alternatively, the computer device can also determine whether a target person exists within the preset range around the control device based on characteristics such as clothing, shoes, and name tags of the people within the preset range around the control device. This embodiment does not limit the method used to determine whether a person around the control device is a target person. By identifying people within the preset range around the control device, the trigger signal triggered by a person with control authority over the control device is accurately identified. Only when the trigger signal meets preset enabling conditions can the patient support platform be controlled through the control device. By identifying the control device switch, the person, and the trigger signal, the possibility of misoperation of the control device by persons other than the target person can be minimized, improving the safety of the scanning process.

[0104] In the control method described above for controlling the control device of the patient support platform, in response to the start command of the control device, the method detects whether there are personnel within a preset range around the control device; if personnel are present, their facial information is collected; and based on the personnel's facial information, it verifies whether the personnel are the target personnel. This method, when personnel are present within a preset range around the control device, can accurately determine whether the personnel have control authority over the control device by collecting their facial information and based on that information, thus accurately identifying whether the personnel are the target personnel.

[0105] In one embodiment, such as Figure 10 As shown, the specific steps for determining whether a person is the target person based on their facial information include the following:

[0106] S501, matching the facial information of personnel with the facial information pre-stored in the information database; the information database stores facial information of personnel who have control over the control device.

[0107] In this embodiment, the computer device can pre-capture images of personnel with control over the device using a camera, extract facial information of the target personnel from the images, and store the facial information in an information database. During the matching process, the computer device can match the personnel's facial information with all facial information in the information database to determine the similarity between the personnel's facial information and any facial information in the database. If any similarity score is greater than a preset similarity threshold, the match is considered successful; if all similarities are less than the preset similarity threshold, the match is considered unsuccessful.

[0108] S502, if a match is successful, the person is identified as the target person.

[0109] In this embodiment of the application, if a match is successful, it indicates that the person has control over the device. In this case, the person can be directly identified as the target person.

[0110] In the aforementioned control method for the control equipment of the patient support platform, the facial information of a person is matched with facial information pre-stored in an information database. The information database stores facial information of individuals with control permissions over the control equipment. If a match is successful, the person is identified as the target individual. This method accurately determines whether a person is the target individual by matching their facial information with that of individuals with control permissions and based on the matching result.

[0111] Once the target personnel control the patient support platform to move to the preset position, they will no longer operate the control device. Therefore, an embodiment is provided to describe in detail the state switching process of the control device in this situation. The specific content of the state switching process of the control device includes the following steps:

[0112] If no control signal is received within a preset time period, the control device switch will switch from the enabled state to the off state.

[0113] During the process of the target person operating the control device to move the patient support platform, the control device remains enabled. If the target person does not operate the control device within a preset time (e.g., 5 seconds), the computer device can determine that the target person does not need to control the movement of the patient support platform. In this case, the computer device can switch the control device from the enabled state to the disabled state.

[0114] In the control method described above for controlling the control device of the patient support platform, if no control signal is received within a preset time period, the control device switch changes from an enabled state to an off state. This method detects the duration of control signal reception and controls the control device to switch states if no control signal is received within the preset time period. This prevents accidental operation of the control device by other personnel and avoids safety accidents.

[0115] After all scan preparations are completed, the medical device enters the scanning state. The following example will provide a detailed explanation of the control device status when the medical device enters the scanning state. Figure 11 As shown, the process includes the following:

[0116] S601, detects the working status of the control equipment.

[0117] In this embodiment, the computer device can determine whether the scan start button in the medical device is on. If the scan start button is not on, the operating state of the control device is active; if the scan start button is on, the operating state of the control device is inactive. Alternatively, the computer device can determine whether the control device is active based on the movement state of the patient support platform. For example, if the patient support platform is in motion, the operating state of the control device is active; if the patient support platform is not in motion, the operating state of the control device is inactive.

[0118] S602, when the working state is the preset state, controls the control device to switch to the disconnect state.

[0119] As an example, in this embodiment of the application, if it is determined that the operating state of the control device is not working, the power supply of the control device is directly cut off, and the control device is controlled to be in a disconnected state, thus ensuring the safety of the scanning process. As another example, in this embodiment of the application, if it is determined that the operating state of the control device is a state where the continuous working time exceeds a preset time (e.g., several hours), the control device can be switched to a disconnected state to reduce the energy consumption of the control device and avoid damage caused by the control device working for too long.

[0120] It should be noted that the power switch for the control device can be either a hardware switch or a software switch. A hardware switch can be located on the patient support platform base, while a software switch can be located on the control panel. When the power switch is on and the control device is operational, the movement of the patient support platform can be controlled. When the power switch is on but the control device is not operational, the movement of the patient support platform cannot be controlled. When the power switch is off, the movement of the patient support platform cannot be controlled.

[0121] Whether it's a simple scanning process or a surgical intervention, the control equipment that moves the patient support platform is powered off during scanning or surgical intervention scenarios. In interventional surgery scenarios, a new foot pedal is connected and activated to control CT exposure.

[0122] In the control method described above for controlling the manipulator of the patient support platform, the operating status of the manipulator is detected; if the operating status is a preset state, the manipulator is switched to a disconnected state. This method, by detecting the operating status of the manipulator and cutting off its power when it is in a preset state, avoids accidental stepping during scanning and ensures safety during the scanning process.

[0123] Controlling a device's switch can be implemented not only through hardware switches but also through software switches. The following example illustrates a specific method using a software switch. The software switch can be located on the control panel of a medical device or the control panel of a computer device. Again, using a foot-operated device as an example... Figure 12 This is a schematic diagram of the control panel. As shown, this control panel is the service settings interface, which includes daily services and other settings. On the other settings screen, there is a system restart prompt time, below which the specific execution time can be set, for example, 23:23. It also includes the configuration of the foot pedal for the control bed, with the foot pedal switch having enabled and disabled states. Users can select the foot pedal switch state by clicking the enabled or disabled state; when enabled, the foot pedal switch is on; when disabled, the foot pedal switch is off.

[0124] It is understood that the foot pedal device can control the movement of the scanning bed under any of the following conditions: the foot switch is in an enabled state, the trigger signal generated by the target person operating the foot pedal device satisfies the foot pedal enabling condition, the foot switch is in an enabled state, and the trigger signal generated by the target person operating the foot pedal device satisfies the foot pedal enabling condition. The foot switch being in an enabled state can be either the foot switch on the control panel or a hardware switch.

[0125] Figure 13 This diagram illustrates an interventional surgery scenario. When no interventional surgery is required, the scanning bed can be moved using foot pedals positioned around it. For scenarios requiring interventional surgery, a new foot pedal is connected externally. When an interventional surgery scenario is detected, or when the new foot pedal is connected, the existing foot pedals around the scanning bed are disabled, while the new foot pedal is enabled. In this state, the new foot pedal controls the movement of the scanning bed.

[0126] As a specific embodiment of this application, taking a foot pedal device as the control device and a scanning bed as the patient support platform as an example, Figure 14 As shown, the control method for the control device used to control the patient support platform includes:

[0127] S701, Determine whether the foot pedal switch used to control the foot pedal device is in the enabled state;

[0128] S702, when it is determined that the foot pedal switch is in the enabled state, in response to the foot pedal start command, detect whether there are personnel within a preset range around the foot pedal;

[0129] S703, if present, collect the facial information of the personnel;

[0130] S704, matching the facial information of personnel with the facial information pre-stored in the information database;

[0131] S705, if a match is successful, the person will be identified as the target person;

[0132] S706, detects trigger signals generated by the target person operating the foot pedal device;

[0133] S707, determine whether the trigger signal meets the preset control enable conditions;

[0134] S708 generates a control signal for controlling the target device when the trigger signal meets the control enable condition.

[0135] S709, detects the working status of the foot pedal device;

[0136] S710, when the working state is the preset state, controls the foot pedal device to be in the off state.
