[0047] 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.

[0048] The technical background of the embodiments of this application will be described below.

[0049] Single-photon emission computed tomography (SPECT) is one of the most commonly used diagnostic imaging techniques, and in today's burgeoning field of integrated diagnostic and therapeutic technologies, SPECT equipment is one of the most important tools. Active quality control and calibration of SPECT systems typically require the replacement of multiple collimators or calibration fixtures for measurement, and this replacement process is usually manual, making it cumbersome and time-consuming. In related technologies, SPECT system collimators and quality control / calibration fixtures are primarily manually assembled and disassembled. The collimator is equipped with a dedicated collimator replacement cart, which can carry the collimator to be installed and manually move it to the SPECT probe; once the probe is close to the cart, it is manually aligned, and the collimator is slid along the probe rail or mounted on the probe.

[0050] Known SPECT systems offer fully automated collimator installation and removal, as well as partial active quality control. Typically, the SPECT bed is used for collimator replacement and radiation source manipulation; the bed automatically approaches the SPECT probe, the collimator stored under the bed automatically slides into the probe, and the radiation source automatically extends. However, due to space limitations, existing scanning beds can only store two collimators and cannot store detector calibration fixtures. Therefore, a complete calibration workflow cannot be completed, and much of the work still requires manual operation.

[0051] Based on this, this application provides a quality control method for medical devices. When performing quality control on a medical scanning device, the scanning bed is moved to bring the radiation source on the scanning bed into the imaging field of view of the detector in the medical scanning device, causing it to emit radiation that strikes the detector for image acquisition. Simultaneously, the loading device is controlled to identify the components required for quality control and install or remove these components from the detector. Based on this, scanned images are acquired using the radiation emitted by the radiation source, and the quality control results of the medical scanning device are obtained through analysis of the scanned images. In this process, the scanning bed is directly controlled to place the radiation source in a designated position, and the loading device is controlled to identify and operate the components required for quality control. This simplifies the placement, installation, and removal of the required components, enabling the detector to quickly and accurately acquire scanned images and rapidly obtain the quality control results of the medical scanning device, thus improving the operational efficiency of quality control. Furthermore, the entire quality control process is fully automated, requiring no manual intervention, saving time and further improving operational efficiency.

[0052] It should be noted that the beneficial effects or technical problems solved by the embodiments of this application are not limited to this one, but may also be other implicit or related problems. For details, please refer to the description of the embodiments below.

[0053] The following describes the application environment of the quality control method for medical devices provided in the embodiments of this application, which can be applied to, for example... Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed in the cloud or on other network servers. Optionally, terminal 102 can be used to trigger quality control requests for medical devices, enabling server 104 to perform quality control on the medical scanning device and determine the quality control results. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. Portable wearable devices can include smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0054] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0055] In one exemplary embodiment, such as Figure 2 As shown, a quality control method for medical devices is provided, which is applied to... Figure 1 Taking server 104 as an example, the explanation includes the following steps 201 to 203. Wherein:

[0056] S201, in response to a quality control request for a medical scanning device, controls the movement of the scanning bed of the medical scanning device until the radiation source on the scanning bed is within the imaging field of view of the detector in the medical scanning device; and, based on the quality control object, controls the loading device to identify the device required for quality control and operates the device required for quality control on the detector; the operation includes removal or installation.

[0057] A quality control request for a medical scanning device refers to a request triggered when the server's quality control application needs to perform quality control on the medical scanning device. Naturally, upon receiving this quality control request, the server needs to perform quality control on the medical scanning device to determine the quality control result. The medical scanning device is a SPECT device, and the quality control includes device quality control and device calibration.

[0058] In one embodiment, the request is triggered by the user through the interface in the quality control application; wherein, the triggering method includes, but is not limited to, clicking on an external input device, voice control, touch screen triggering, etc., and the triggering method is not limited in this embodiment.

[0059] In another embodiment, the request is triggered according to a preset automatic program; for example, if the server detects that the current time has reached the preset quality control cycle of the medical scanning device, it automatically triggers the quality control request of the medical scanning device according to the preset program.

[0060] The radioactive source can be a solid source, an easily filled vial / tube liquid source, or a radioactive source phantom, etc. In one embodiment, the radioactive source is placed in a water phantom, which can be of any shape. In this embodiment, the radioactive source (such as a radioactive source placed in a water phantom) can be placed on the scanning bed of a medical scanning device in advance. Optionally, one or more radioactive sources can be placed on the bed at a time, and a large water phantom (with the radioactive source placed inside) can also be used. Typically, the quality control process needs to be performed multiple times, and the radioactive sources used each time may be different. Therefore, to improve the efficiency of quality control, all the necessary radioactive sources can be placed on the scanning bed at once. The placement positions of different radioactive sources are different, and each radioactive source can be placed at a different position on the scanning bed according to the pre-marked positions of different radioactive sources.

[0061] The loading device refers to a transport device that can be used to load components. It can be an automated cart used to load the components required for quality control of medical scanning equipment and transport them to a designated location. In the embodiments of this application, the loading device can also automatically identify the components required for quality control and install them in the designated location or remove them from the detector. That is, the loading device has the functions of automatically identifying components, automatically loading components, automatically transporting components, automatically installing components, and automatically removing components.

[0062] The equipment required for quality control refers to the devices needed for quality control of medical scanning equipment, including different types of collimators and various types of quality control and calibration fixtures. Collimators can include (multi-)pinhole collimators, parallel-hole collimators, fan-beam collimators, tapered-beam collimators, and strip-slit collimators. Fixtures can include multi-hole fixtures, horizontal and vertical slit fixtures, and uniformity fixtures.

[0063] In this embodiment, upon receiving a quality control request for the medical scanning equipment, the scanning bed is controlled to move so that the required radiation source on the scanning bed is within the imaging field of view of the detector in the medical scanning equipment, for emitting radiation to deliver radio frequency to the detector, enabling the detector to acquire an image. Simultaneously, the loading device is also controlled to operate on the quality control components required by the medical scanning equipment. This allows the loading device to identify the required components and install them at a designated location, i.e., attach them to the detector in the medical scanning equipment, or remove them from the detector. For example, since the loading device has functions of automatically identifying, loading, transporting, installing, and removing components, instructions can be sent to the loading device to automatically identify the currently required quality control components, load them, transport them to the detector, and install them on the detector.

[0064] S202, when the radiation from the radiation source reaches the detector, controls the detector to acquire a scanned image of the radiation source.

[0065] When the radiation source is within the imaging field of view of the detector, and the necessary quality control devices are installed on the detector, the radiation source emits rays that pass through the quality control devices mounted on the detector and hit the detector. At this time, the detector of the medical scanning equipment can acquire images and obtain scan images of the radiation source.

[0066] S203, Determine the quality control results of the medical scanning equipment based on the scanned images.

[0067] After acquiring the scanned images, the quality control results of the medical scanning equipment are determined by analyzing the images. For example, if the quality control of a medical scanning equipment requires a lead plate with parallel lead seams, the parallel lead seams in the scanned images can be observed to determine if they are normal. If the lead seams are bent, it indicates that the medical scanning equipment is in an abnormal state, and this is identified as a quality control result of the medical scanning equipment.

[0068] In the quality control method for medical devices provided in this application embodiment, in response to a quality control request for a medical scanning device, the scanning bed of the medical scanning device is controlled to move until the radiation source on the scanning bed is within the imaging field of view of the detector in the medical scanning device. Based on the quality control object, the loading device is controlled to identify the device required for quality control and operate the device required for quality control on the detector. When the radiation from the radiation source reaches the detector, the detector is controlled to acquire a scanning image of the radiation source and the quality control result of the medical scanning device is determined based on the scanning image. The operation includes removal or installation. In this method, during quality control of medical scanning equipment, the scanning bed is moved to position the radiation source within the imaging field of the detector, allowing it to emit radiation that strikes the detector for image acquisition. Simultaneously, the loading device identifies the necessary quality control components and installs or removes them from the detector. Based on this, scanned images are acquired using the radiation emitted from the radiation source, and the quality control results of the medical scanning equipment are obtained through image analysis. This process directly controls the scanning bed to place the radiation source in the designated location and controls the loading device to identify and operate the necessary components, simplifying the placement, installation, and removal of these components. This allows the detector to quickly and accurately acquire scanned images and rapidly obtain the quality control results of the medical scanning equipment, improving operational efficiency. Furthermore, the entire quality control process is fully automated, requiring no manual intervention, saving time and further enhancing operational efficiency.

[0069] Based on the above embodiments, an embodiment of the process of controlling the movement of the scanning bed of the above-mentioned medical scanning device will be provided for description.

[0070] In one exemplary embodiment, such as Figure 3 As shown, controlling the movement of the scanning bed of the medical scanning device until the radiation source on the scanning bed is within the imaging field of view of the detector in the medical scanning device includes:

[0071] S301, when the scanning bed moves to the preset position, controls the detector to acquire candidate scanning images of the radiation source.

[0072] The preset position is the initial position of the scanning bed. After moving the scanning bed to this initial position, the position of the scanning bed needs to be adjusted to accurately move the scanning bed to the specified position.

[0073] In one embodiment, a laser locator can be used to determine whether the scanning bed has accurately moved to a preset position. For example, the laser locator can be installed on the scanning bed, and the scanning bed will emit a laser beam to illuminate the target object (such as a detector) during its movement. Based on the reflected information, the current position information of the scanning bed is obtained. Then, the position information is compared with a preset position. If the position information matches the preset position, it is determined that the scanning bed has accurately moved to the preset position.

[0074] In this embodiment of the application, after the scanning bed is accurately moved to a preset position, the detector is controlled to acquire images and obtain candidate scanning images, so as to make detailed adjustments to the position of the scanning bed based on the candidate scanning images.

[0075] S302, based on the candidate scan images, adjust the position of the scanning bed until the radiation source is within the imaging field of view of the detector.

[0076] In this embodiment, the detector's imaging field of view refers to the precise target location of the radiation source, where the image quality of the scanned image acquired is highest. Therefore, after moving the scanning bed to its initial position, further positional adjustments are needed to ensure that the radiation source on the scanning bed is positioned precisely at the target location.

[0077] After acquiring candidate scan images of the radioactive source, the position of the scanning bed is adjusted based on the location information of the radioactive source in the candidate scan images.

[0078] For example, spatial location information of the radiation source is obtained based on candidate scan images; the position of the scanning bed is adjusted according to the gap between the spatial location information and the expected spatial location of the radiation source so that the radiation source is within the imaging field of view of the detector.

[0079] Spatial location information of a radioactive source refers to the actual physical location of the radioactive source.

[0080] In this embodiment of the application, the acquired candidate scan image includes the position information of the radiation source in the image. According to the preset conversion relationship, the image position information of the radiation source can be converted into the spatial position information of the radiation source. Then, the spatial position information of the radiation source is compared with the expected spatial position of the radiation source. Based on the difference between the spatial position information of the radiation source and the expected spatial position of the radiation source, the scanning bed is adjusted to move in the corresponding direction so that the radiation source on the scanning bed is at the accurate target position.

[0081] In this embodiment, the position information of the radiation source in the candidate scan image is converted into the position information of the radiation source in the actual space by using the candidate scan image of the radiation source. Based on the difference between the actual spatial position information and the expected position information of the radiation source in the actual space, the scanning bed is moved to make the actual spatial position of the radiation source overlap with the expected actual spatial position, so that the radiation source is accurately placed at the designated target position, thereby improving the placement efficiency and accuracy of the radiation source.

[0082] In the quality control method for medical devices provided in this application, when the scanning bed is moved to a preset position, the detector is controlled to acquire candidate scan images of the radiation source. Then, based on the candidate scan images, the position of the scanning bed is adjusted until the radiation source is within the imaging field of view of the detector. In this method, the scanning bed is first moved to an initial position, and then a current scan image of the radiation source is acquired at that initial position. Based on this current scan image, the position of the scanning bed is finely adjusted so that the radiation source on the scanning bed is accurately within the imaging field of view of the detector, thereby acquiring more accurate and higher-quality scan images and improving the accuracy of the quality control results.

[0083] Based on the above embodiments, an embodiment is provided to illustrate the process of identifying and operating the devices required for quality control.

[0084] In one exemplary embodiment, such as Figure 4 As shown, the loading device is connected to the host computer of the medical scanning equipment; the components required for quality control include collimators or quality control fixtures; based on the quality control object, the loading device is controlled to identify the components required for quality control, including:

[0085] S401, when the quality control object is a collimator or scanning system, the host computer sends a collimator identification request to the loading device to instruct the loading device to move to the quality control device storage cabinet, and identifies the target collimator from the quality control device storage cabinet based on the collimator model information carried in the collimator identification request, and loads the target collimator if the target collimator is identified.

[0086] The components required for quality control include collimators or quality control fixtures, and the quality control fixtures also include calibration fixtures. A quality control component storage cabinet refers to a storage device that stores the components required for quality control, including all collimators and quality control fixtures.

[0087] In this embodiment, when the quality control object is a collimator or scanning system, a collimator is installed on the detector for quality control. The host computer sends a collimator identification request to the loading device, enabling the loading device to identify the required collimator in the quality control device storage cabinet. The collimator identification request carries relevant information about the required collimator, such as its model information. Upon receiving the collimator identification request, the loading device moves to the quality control device storage cabinet, identifies the target collimator from the storage cabinet based on the information carried in the request, and automatically loads the target collimator onto the loading device.

[0088] S402, when the quality control object is a detector, the host computer sends a tooling identification request to the loading device to instruct the loading device to move to the quality control device storage cabinet, and identifies the target quality control tooling from the quality control device storage cabinet based on the tooling type information carried in the tooling identification request, and loads the target quality control tooling if the target quality control tooling is identified.

[0089] When the quality control object is a detector, a detector fixture is installed on the detector for quality control. The host computer sends a fixture identification request to the loading device, enabling the loading device to identify the required fixture in the quality control device storage cabinet. The fixture identification request carries relevant information about the required fixture, such as fixture type information. After receiving the fixture identification request, the loading device moves to the quality control device storage cabinet, identifies the corresponding quality control fixture from the storage cabinet based on the information carried in the request, and automatically loads the target quality control fixture onto the loading device.

[0090] The identification methods for loading equipment can include mechanical switches (such as contact switches), photoelectric switches (such as phototransistors), electromagnetic sensors (such as Hall effect devices), RFID tags, barcodes / QR codes, or other sensing mechanisms.

[0091] Taking RFID tags as an example, each collimator and quality control tooling in the quality control device storage cabinet is affixed with an RFID tag. Each RFID tag contains information about the corresponding device. For example, the RFID tag on each collimator contains the model information of the collimator, and the RFID tag on each quality control tooling contains the type information of the quality control tooling.

[0092] The loading equipment is equipped with an information identifier, which includes an RFID tag antenna and an antenna receiving board. When the loading equipment moves to a certain distance from the quality control device storage cabinet, the RFID tags on the collimators and quality control fixtures will transmit the corresponding information (collimator model information, fixture type information) to the antenna receiving board through the RFID tag antenna of the loading equipment. The antenna receiving board receives the information from each RFID tag and sends this information to the control unit of the loading equipment. The control unit compares this information with the collimator model information or fixture type information carried in the identification request to identify the corresponding collimator or quality control fixture. The collimator or quality control fixture can then be placed at the corresponding position on the loading equipment by the robotic arm of the loading equipment.

[0093] After successfully loading the corresponding collimator or quality control fixture, the loading equipment automatically moves to the location of the detector and uses a robotic arm to attach the loaded collimator or quality control fixture to the detector.

[0094] In the quality control method for medical devices provided in this application, when the quality control object is a collimator or scanning system, the host computer sends a collimator identification request to the loading device to instruct the loading device to move to the quality control device storage cabinet. Based on the collimator model information carried in the collimator identification request, the host computer identifies the target collimator from the quality control device storage cabinet and loads the target collimator if identified. When the quality control object is a detector, the host computer sends a tooling identification request to the loading device to instruct the loading device to move to the quality control device storage cabinet. Based on the tooling type information carried in the tooling identification request, the host computer identifies the target quality control tooling from the quality control device storage cabinet and loads the target quality control tooling if identified. In this method, due to its inherent characteristics, upon receiving the identification request, the loading device automatically moves to the quality control device storage cabinet to identify the required device based on the information carried in the request, and automatically loads the identified device into the corresponding position on the loading device. This improves the accuracy of device identification and loading efficiency, thereby improving the accuracy and efficiency of quality control.

[0095] Before the loading equipment operates the quality control devices on the detector, it can first check whether there are other devices mounted on the detector. If so, remove them and send them back to the quality control device storage cabinet before installing the current quality control devices.

[0096] Based on this, in an exemplary embodiment, operating the necessary quality control devices on the detector includes:

[0097] The host computer sends a historical device detection request to the loading equipment to instruct the loading equipment to detect whether a historical device is mounted on the detector, and if a historical device is detected on the detector, to remove the historical device from the detector and install the target collimator or target quality control fixture; the historical device includes a historical collimator or historical quality control fixture.

[0098] After the loading equipment transports the target collimator or target quality control fixture to the detector's location, the host computer sends a historical device detection request to the loading equipment, enabling the loading equipment to detect whether the detector is equipped with a historical collimator or historical quality control fixture. For example, the loading equipment can still detect whether the detector is equipped with a historical collimator or historical quality control fixture using RFID tags. After the loading equipment moves to the detector's location, it continues to receive information via the RFID tag antenna and antenna receiving board. If the antenna receiving board does not receive any collimator model information or tooling type information other than the target collimator model information or the target quality control tooling type information within a preset time, it indicates that the detector is not carrying a historical collimator or historical quality control tooling. If the antenna receiving board receives collimator model information or quality control tooling type information other than the target collimator model information or the target quality control tooling type information within the preset time, it indicates that a historical collimator or historical quality control tooling is currently carried on the detector. In this case, the loading equipment removes the historical collimator or historical quality control tooling from the detector using a robotic arm, and then installs the target collimator or target quality control tooling. After installing the target collimator or target quality control tooling, the historical collimator or historical quality control tooling is loaded onto the loading equipment and moved to the quality control device storage cabinet, where it is then returned to the quality control device storage cabinet.

[0099] In this embodiment of the application, the quality control process is divided into several types based on the installation status of the components required for quality control, including quality control without collimator and without tooling, quality control without collimator but with tooling, and quality control with collimator but without tooling. It can be understood that it can be further subdivided based on different collimator models and different tooling types.

[0100] Based on the different quality control processes described above, in actual operation, it is necessary to operate the required devices for quality control based on the previous and current processes. Taking the previous process as having no collimator and no tooling, and the current process as having no collimator but with tool A as an example, the loading device receives a tool identification request, which carries the type information of tool A. The loading device moves to the quality control device storage cabinet, identifies tool A based on its type information, and loads it into the corresponding position on the loading device. Then, it moves to the detector and mounts tool A onto the detector. Before mounting tool A, the loading device first checks whether the detector currently has a historical collimator or historical quality control tool mounted on it. Since the previous process was quality control without a collimator and no tooling, the loading device did not identify any historical devices mounted on the detector, so it directly mounts tool A onto the detector.

[0101] Furthermore, after successfully mounting fixture A, a scanning image is acquired by the detector, and the quality control result of the current process is determined based on the acquired scanning image. Following this, other processes will be performed, such as quality control for devices with collimator A but without fixtures. These processes also follow the same method: upon receiving a request, the loading equipment identifies the new device based on the information carried in the request and loads the new device at the corresponding position on the loading equipment. Then, it moves to the detector to mount the new device. Before mounting the new device on the detector, it first checks whether there are any existing devices on the detector. If so, the existing devices are removed before mounting the new device, and a new quality control process is executed until the complete quality control process is finished.

[0102] In the quality control method for medical devices provided in this application embodiment, before mounting the target collimator or target quality control fixture, the loading device first identifies whether a historical collimator or historical quality control fixture is mounted on the detector. If so, the historical device is removed before mounting the target collimator or target quality control fixture. In this process, the complicated process of loading and installing the new device and then removing and putting back the historical device is avoided, simplifying the device operation process, improving operation efficiency, and thus improving the efficiency of quality control.

[0103] Based on the above embodiments, an embodiment of the process for determining the quality control results is provided for illustration.

[0104] In one exemplary embodiment, such as Figure 5 As shown, quality control includes equipment quality control; quality control results include equipment quality control results; based on the scanned images, the quality control results of the medical scanning equipment are determined, including:

[0105] S501, acquire image feature information of the scanned image, and determine the status information of the medical scanning device based on the image feature information.

[0106] In this embodiment, quality control includes equipment quality control, and the quality control results include equipment quality control results. The content of equipment quality control includes spatial uniformity, spatial linearity, spatial resolution, rack and probe skew, energy linearity, and energy resolution.

[0107] After acquiring the scanned images, the medical scanning equipment is assessed for its status based on its image feature information. This status information includes the texture of the projection image after mounting the fixture, the shape of the projection image of a known radiation source in different orientations, and the energy spectrum response of the known radiation source. Status information includes spatial uniformity, spatial linearity, spatial resolution, probe tilt, energy linearity, and energy resolution.

[0108] S502, the status information is determined as the equipment quality control result of the medical scanning equipment.

[0109] After obtaining the status information of the medical scanning equipment, this status information is determined as the equipment quality control result. If the equipment quality control result indicates that the medical scanning equipment is abnormal, then the medical scanning equipment needs to be calibrated.

[0110] The quality control method for medical devices provided in this application includes equipment quality control, and the quality control result includes the equipment quality control result. The method involves acquiring image feature information of a scanned image, determining the status information of the medical scanning device based on the image feature information, and then using this status information as the equipment quality control result. In this method, if the quality control is equipment quality control, after acquiring the scanned image, the status of the medical scanning device is judged based on the image feature information of the scanned image to quickly obtain the status information of the medical scanning device. This status information is the equipment quality control result, enabling timely detection of equipment abnormalities, prompt intervention, and improved equipment reliability and imaging quality.

[0111] Based on the above embodiments, another embodiment of the process for determining the quality control results is provided for illustration.

[0112] In one exemplary embodiment, such as Figure 6 As shown, quality control includes equipment calibration; quality control results include equipment calibration results; based on the scanned images, the quality control results of the medical scanning equipment are determined, including:

[0113] S601, Based on the scanned image, determine the equipment calibration parameters of the medical scanning device.

[0114] In this embodiment, quality control includes equipment calibration, and the quality control result includes the equipment calibration result. The equipment calibration content includes spatial uniformity, spatial linearity, spatial resolution, rack and probe skew, energy linearity, and energy resolution.

[0115] During equipment calibration, after acquiring the scanned image, the corresponding equipment calibration parameters are calculated based on the content to be calibrated. For example, taking energy resolution as an example, energy information is extracted from the scanned image, and then the energy resolution parameter is calculated based on the energy information. This energy resolution parameter is the equipment calibration parameter corresponding to the energy resolution.

[0116] S602, Based on the equipment calibration parameters, adjust the parameters of the medical scanning equipment to obtain the equipment calibration results of the medical scanning equipment.

[0117] After obtaining the equipment calibration parameters, the corresponding equipment parameters in the medical scanning equipment are adjusted based on these parameters to obtain the adjusted equipment parameters, and the adjusted equipment parameters are determined as the equipment calibration result of the medical scanning equipment.

[0118] Taking energy resolution as an example, after obtaining the energy resolution parameters, the energy window width and energy center of the medical scanning device are adjusted based on the difference between the energy resolution and the expected energy resolution. The adjusted energy window width and energy center are then used as the energy resolution correction result of the medical scanning device.

[0119] The quality control method for medical devices provided in this application includes device calibration, and the quality control result includes device calibration result. Based on the scanned image, device calibration parameters of the medical scanning device are determined, and then the parameters of the medical scanning device are adjusted according to the device calibration parameters to obtain the device calibration result. In this method, during device calibration, the scanned image is processed to calculate the corresponding device calibration parameters. Based on these parameters, the relevant device parameters of the medical scanning device are adjusted, restoring the medical scanning device to normal operation and improving its stability.

[0120] In one exemplary embodiment, a quality control system for a medical device is provided. The quality control system includes a host computer, a medical scanning device, and a loading device. The host computer is connected to both the medical scanning device and the loading device. The host computer is also connected to the scanning bed of the medical scanning device.

[0121] The host computer controls the movement of the scanning bed until the radiation source on the scanning bed is within the imaging field of view of the detector in the medical scanning equipment; and, based on the quality control object, controls the loading equipment to identify the devices required for quality control and to operate the devices required for quality control on the detector; when the radiation from the radiation source reaches the detector, controls the detector to acquire the scanning image of the radiation source; and determines the quality control result of the medical scanning equipment based on the scanning image; operations include removal or installation.

[0122] In this embodiment, the host computer is connected to the medical scanning equipment, the scanning bed, and the loading device. It can control the movement of the scanning bed to ensure the radiation source on the scanning bed is within the imaging field of view of the detector in the medical scanning equipment. Simultaneously, it can control the loading device to identify the necessary quality control components and install them onto the detector. After the radiation source is successfully moved into the detector's imaging field of view and the quality control components are successfully installed, the detector acquires a scanned image of the radiation source, and analyzes this image to obtain the quality control results of the medical scanning equipment.

[0123] In the quality control system for medical devices provided in this application embodiment, when performing quality control on a medical scanning device, the scanning bed is moved to bring the radiation source on the scanning bed into the imaging field of view of the detector in the medical scanning device, so that the radiation source emits rays that hit the detector for image acquisition. At the same time, the loading device is controlled to identify the components required for quality control and to install or remove the components from the detector. Based on this, the scanning images are acquired through the radiation emitted by the radiation source, and the quality control results of the medical scanning device are obtained by analyzing the scanning images. In this process, the scanning bed is directly controlled to place the radiation source in the designated position, and the loading device is controlled to identify and operate the components required for quality control. This simplifies the operation process of placing, installing, and removing the components, enabling the detector to quickly and accurately acquire scanning images and quickly obtain the quality control results of the medical scanning device, thus improving the operational efficiency of quality control. At the same time, the entire quality control operation process is fully automatic, requiring no manual intervention, saving time and further improving the operational efficiency of quality control.

[0124] In another embodiment, the process of placing the radioactive source and installing the necessary equipment for quality control is described.

[0125] like Figure 7 As shown, the quality control is exemplified by only mounting a collimator. In (1), it can be seen that no collimator or quality control fixture is mounted on the detector. The loading device identifies the required collimator from the storage cabinet and loads it. Then, in (2), the loading device moves the collimator to the location of the detector and installs the collimator on the detector. In (3), after the detector is installed, the scanning bed is moved by controlling it so that the radiation source is within the imaging field of view of the detector in the medical scanning device.

[0126] In this embodiment, by controlling the loading equipment to identify and operate the devices required for quality control, and directly controlling the scanning bed to place the radiation source in the designated position, the operation process of placing, installing, and removing the required devices is simplified, enabling the detector to quickly and accurately acquire scanning images and improving the operational efficiency of quality control. At the same time, the entire quality control operation process is fully automatic, requiring no manual intervention, saving time costs and further improving the operational efficiency of quality control.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
