[0025] 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.

[0026] The probe switching method provided in this application can be applied to medical devices equipped with probes, such as ultrasound diagnostic equipment, SPECT equipment, and SPECT-CT equipment. The following detailed explanation uses SPECT-CT equipment as an example. The imaging principle of CT (Computed Tomography) involves X-rays emitted by the device passing through the human body. Due to the different densities of various organs and tissues within the body, the energy of the rays detected by the probe also varies, resulting in different degrees of shadowing of different organs in the generated anatomical images. Finally, the data obtained from the scan is processed by a computer to generate cross-sectional images of the body's interior. SPECT imaging involves injecting a single-photon radionuclide imaging agent into the body. The imaging agent adheres to specific physiological tissues or lesions, and the probe collects the rays released by the imaging agent to obtain the corresponding images. SPECT-CT equipment is a multimodal medical device that combines these two imaging methods. In addition to providing SPECT functional information, it also provides anatomical information from CT. By combining the two, it is possible to observe both the anatomical morphology and metabolic status of lesions, achieving a complementary advantage between SPECT and CT.

[0027] The specific workflow of SPECT-CT equipment is quite complex. First, the patient needs to be positioned, including administering medication and immobilizing them. Next, pre-scan planning is performed, where the area to be examined is planned and input into the device. Finally, scanning and reconstruction take place. During operation, the SPECT-CT probe may move differently depending on the area being scanned to facilitate accurate scanning. After the scan, image confirmation and patient release are performed. Currently, if a probe malfunctions during operation, the scanning service will be interrupted. In such cases, maintenance personnel must be called in, which consumes significant manpower and resources, impacts equipment efficiency and hospital operations, and disrupts patient treatment plans.

[0028] Based on this, this application proposes a probe switching method, device, medical equipment, and computer-readable storage medium, which can improve the operating efficiency of medical equipment and prevent disruption to the normal operation of the hospital and inconvenience to patients' treatment plans.

[0029] In one embodiment, such as Figure 1As shown, a probe switching method is provided. Taking the application of this method to medical devices as an example, the method includes the following steps:

[0030] Step S110: In response to the probe switching command, the probe to be switched is switched to the standby probe.

[0031] Specifically, in the medical device of this application embodiment, based on the classification of probe operation, there are at least three types of probes: probes to be switched, spare probes, and normal probes. Each type may include one or more probes. The number of probes to be switched is less than or equal to the number of spare probes, and normal probes are probes that can work normally without switching. For ease of description, the following explanation uses one probe of each type as an example.

[0032] Upon receiving a probe switching command, the medical device will switch the probe to be switched to a backup probe. Specifically, in response to the command, the device will move the probe to be switched away via the rack and relocate the backup probe to its position. The backup probe has the same function as the probe to be switched, ensuring that the corresponding medical examination can still be performed after the switch. The probe switching command can be triggered by various situations, such as a malfunction of the probe to be switched or the need for active replacement with the backup probe.

[0033] Step S120: Synchronize the probe status information of the probe to be switched to the standby probe.

[0034] Specifically, after the medical device switches the probe to be switched to the backup probe, it sends the probe status information of the probe to be switched to the controller of the backup probe for synchronization. The probe status information of the probe to be switched includes probe attitude and probe scanning parameters. The probe attitude refers to the probe's pitch angle, yaw angle, and roll angle relative to the medical device; the probe scanning parameters are used to set the scanning mode. After receiving the probe switching command, the medical device will save a snapshot of the probe status information of the probe to be switched for use during data synchronization. By synchronizing the probe status information, it can be ensured that the backup probe can seamlessly take over the work of the probe to be switched and continue scanning with the same parameters and attitude, thereby maintaining the continuity and consistency of the scan data.

[0035] Step S130: Obtain the relative position information between the backup probe and the normal probe.

[0036] Specifically, after switching the probe to be switched to the backup probe, the medical device needs to calibrate the position of the backup probe to ensure its accuracy. Once the backup probe moves to the position of the probe to be switched, the medical device needs to acquire the relative position information between the backup probe and the normal probe. This relative position information can be obtained by sensor detection or calculated by the positioning module within the medical device. In some embodiments, since the medical device needs to control probe movement, the absolute position information of the probe relative to the medical device can be acquired in real time. When relative position information is needed, it can be calculated by acquiring the absolute position information of both the backup probe and the normal probe.

[0037] Step S140: Determine the position error based on the relative position information and the preset position information.

[0038] Specifically, after acquiring the relative position information between the backup probe and the normal probe, the medical device determines the positional error based on this relative position information and preset position information. The preset position information refers to the pre-set relative positions of the probe to be switched and the normal probe under normal operating conditions. In other words, one position of the normal probe corresponds to one position of the probe to be switched, and also to a relative position between the two probes; this information can be stored in the medical device as a data table. Once the current position of the normal probe is determined, the current preset position information can be determined. The positional error is then determined by calculating the error between the relative position information and the preset position information.

[0039] Step S150: Adjust the current position of the backup probe based on the position error and update the position error until the position error is within the preset error range.

[0040] Specifically, after the medical equipment determines the positional error, it adjusts the current position of the backup probe based on the magnitude of the error. The relative positional information between the adjusted backup probe and the normal probe is then recalculated. The positional error is then recalculated and updated until it falls within the preset error range. A smaller positional error indicates that the current position of the backup probe closely matches the preset positional requirements. When the positional error is determined to be within the preset range, it means that the current position of the backup probe meets the positional error requirements of the medical equipment and satisfies the continuity requirements of the scanning process. At this point, the entire probe switching process is complete.

[0041] The aforementioned probe switching method involves responding to a probe switching command to switch the probe to be switched to a backup probe, then synchronizing the probe status information of the probe to be switched to the backup probe, allowing the backup probe to adjust its probe posture and scanning parameters to match those of the probe to be switched. Next, the relative position information between the backup probe and the normal probe is acquired, and the position error is determined based on the relative position information and preset position information. Finally, the current position of the backup probe is adjusted based on the position error, and the position error is updated until the position error is within the preset error range. In this way, the current position of the backup probe can be precisely adjusted to the position of the probe to be switched before the switch, facilitating the backup probe to continue performing subsequent medical examinations without waiting for maintenance personnel, thereby improving the operating efficiency of medical equipment and preventing inconvenience to the patient's treatment plan.

[0042] In one embodiment, such as Figure 2 As shown, step S110, the step of switching the probe to be switched to the standby probe, includes:

[0043] Step S111: Obtain the switching position information of the probe to be switched and the backup position information of the backup probe.

[0044] Specifically, in this embodiment, when switching the probe to be switched to the backup probe, the medical device first obtains the current position information of the probe to be switched, i.e., the switching position information. Simultaneously, it obtains the current position information of the backup probe, i.e., the backup position information. In some embodiments, during the operation of the medical device, the switching position information of the probe to be switched changes continuously, and the backup probe also moves along with the probe to be switched; therefore, the backup position information also changes continuously.

[0045] Specific examples, such as Figure 3 As shown in one embodiment, when the medical device is in H-mode scanning mode, the three probes are positioned such that two main probes are symmetrically arranged at 180°, and a backup probe is positioned at a 90° angle to the main probes. When the medical device is working, the three probes rotate simultaneously around the treatment bed to perform the corresponding scanning process. When it is necessary to switch one of the main probes, the medical device acquires the switching position information of the probe to be switched (main probe 1 or main probe 2) and the backup position information of the backup probe. Figure 4As shown in one embodiment, when the medical device is in L-shaped scanning mode, the three probes are positioned such that two main probes are set at a 90° angle, and the backup probe is set at a 135° angle to the main probes. When the medical device is working, the three probes will rotate around the treatment bed simultaneously to perform the corresponding scanning process. When it is necessary to switch one of the main probes, the medical device will obtain the switching position information of the probe to be switched (main probe 1 or main probe 2) and the backup position information of the backup probe.

[0046] Step S112: Move the backup probe based on the switching location information, and move the probe to be switched based on the backup location information.

[0047] Specifically, after acquiring the switching position information of the probe to be switched and the backup position information of the backup probe, the medical device moves the backup probe according to the switching position information of the probe to be switched, so as to move the backup probe to the position of the probe to be switched. At the same time, it moves the probe to be switched according to the backup position information of the backup probe, so as to move the probe to be switched to the position of the backup probe, thereby completing the switching between the probe to be switched and the backup probe. In some other embodiments, the probe to be switched may not move to the position of the backup probe, but may move the probe according to a preset position information, so as to move the probe to be switched away from its current position.

[0048] In one embodiment, such as Figure 5 As shown, the probe switching method also includes:

[0049] Step S160: Monitor the current working status of all probes.

[0050] Specifically, in this embodiment, the medical device determines whether to switch probes based on their operating status. The medical device uses a health monitoring module to monitor the current operating status of all probes in real time. When a probe is working normally, its operating status is normal; when a probe malfunctions, its operating status is faulty. It is understood that the backup probe is generally in standby mode and is only activated to perform the probe switching method described above when a probe switching is required.

[0051] Step S170: Select the probe whose current working state is faulty as the probe to be switched.

[0052] Specifically, during the monitoring of the current operating status of all probes, if the medical device detects a probe in a faulty state, it will be designated as a probe to be switched. The switch will then be performed using subsequent probe switching steps. It is understood that the number of probes to be switched is generally one; therefore, a backup probe is also typically set to one. In some other embodiments, the number of probes to be switched can be multiple, and correspondingly, the number of backup probes can also be multiple, with the number of probes to be switched being less than or equal to the number of backup probes.

[0053] In one embodiment, such as Figure 6 As shown, after monitoring the current operating status of all probes in step S160, the probe switching method further includes:

[0054] Step S180: When a probe is detected to be in a faulty state, a probe switching prompt interface is displayed.

[0055] Specifically, in this embodiment, when the medical device monitors the current operating status of all probes, if it detects that at least one probe is in a faulty state, it will display a probe switching prompt interface on the user interface. This prompt interface indicates to the user that a faulty probe needs to be switched, and the user can obtain the probe switching command through this interface. The probe switching prompt interface includes a "Switch Probe" button and a "Do Not Switch Probe" button. The "Switch Probe" button triggers the probe switching command, and the medical device responds by switching the probe to be switched as a backup probe. When the user triggers the "Do Not Switch Probe" button, the medical device will stop operating, awaiting maintenance personnel to repair the faulty probe.

[0056] In one embodiment, such as Figure 7 As shown, the probe switching method also includes:

[0057] Step S190: When the position error is within the preset error range, the continue processing interface is displayed.

[0058] Specifically, in this embodiment, after adjusting the current position of the backup probe based on the position error, the medical device recalculates and updates the position error until it falls within a preset error range. Once the position error is within this range, the medical device displays a "Continue Processing" interface on the user interface, indicating the user's subsequent processing method. The "Continue Processing" interface includes a "Rescan" button and a "Continue Scan" button. When the user triggers the "Rescan" button, the medical device re-executes the current medical examination using the backup probe. When the user triggers the "Continue Scan" button, the medical device continues the current medical examination using the backup probe. Since the errors in the position and status information between the backup probe and the probe to be switched are within the allowable error range, accurate scan data can be obtained by continuing the subsequent scanning task using the backup probe, thus completing the supplementary scan.

[0059] In one embodiment, such as Figure 8 As shown, after displaying the continue processing interface in step S190, the probe switching method further includes:

[0060] Step S200: In response to the probe scanning command, scan is performed using both the backup probe and the normal probe to obtain scan data.

[0061] Specifically, after the medical device displays the "Continue Processing" interface on the user interface, it can obtain corresponding probe scanning commands through user trigger actions. Probe scanning commands include: a rescan command and a continue scan command. The rescan command is obtained after being triggered by the rescan button, and the continue scan command is obtained after being triggered by the continue scan button. Upon receiving a rescan command, the medical device re-scans using both the backup and normal probes; upon receiving a continue scan command, the medical device continues scanning using both the backup and normal probes. Corresponding scan data is obtained during the probe scanning process.

[0062] Step S210: Correct the scanning data based on the position error to obtain corrected data.

[0063] Specifically, during the scanning process, the position of the adjusted backup probe still has a certain error. Therefore, the medical device uses a correction algorithm to correct the scan data based on this positional error. This algorithm adjusts or compensates for the image distortion or artifacts caused by the backup probe's positional error, based on the deviation between the actual and theoretical positions of the backup probe. The resulting corrected data can be obtained through various methods such as linear interpolation, nonlinear transformation, and iterative reconstruction.

[0064] Step S220: Determine the scanned image based on the calibration data.

[0065] Specifically, after the medical device corrects the original scan data to obtain corresponding corrected data, it uses the corrected data to generate the final scan image through an image reconstruction algorithm. The image reconstruction process varies depending on the type of medical device. The data correction steps in this embodiment enable the corrected data to more accurately reflect the true shape and position information of the scanned object, reducing image distortion or artifacts caused by probe position errors.

[0066] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. 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.

[0067] Based on the same inventive concept, this application also provides a probe switching device for implementing the probe switching method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more probe switching device embodiments provided below can be found in the limitations of the probe switching method described above, and will not be repeated here.

[0072] The position error determination module 340 is used to determine the position error based on relative position information and preset position information;

[0073] The position adjustment module 350 is used to adjust the current position of the backup probe based on the position error and update the position error until the position error is within the preset error range.

[0074] Each module in the aforementioned probe switching device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of a computer device in hardware form or independent of it, or stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module.

[0075] In one embodiment, the probe switching module 310 is further configured to acquire the switching position information of the probe to be switched and the backup position information of the backup probe; move the backup probe based on the switching position information and move the probe to be switched based on the backup position information.

[0076] In one embodiment, the probe switching device further includes:

[0077] The status detection module is used to monitor the current working status of all probes;

[0078] The probe identification module is used to identify probes that are currently in a faulty state as probes to be switched.

[0079] In one embodiment, the probe switching device further includes:

[0080] The interface display module is used to display a probe switching prompt interface when a probe currently in a fault state is detected. The probe switching prompt interface includes a switch probe button and a do not switch probe button. The switch probe button is used to trigger the probe switching command.

[0081] In one embodiment, the interface display module is further configured to display a continue processing interface when the position error is within a preset error range; wherein the continue processing interface includes a rescan button and a continue scan button.

[0082] In one embodiment, the probe switching device further includes:

[0083] The probe scanning module is used to respond to probe scanning commands to scan with a backup probe and a normal probe to obtain scan data. The probe scanning commands include a rescan command and a continue scan command. The rescan command is triggered by the rescan button, and the continue scan command is triggered by the continue scan button.

[0084] The data correction module is used to correct the scanned data based on the position error to obtain corrected data;

[0085] The image construction module is used to determine the scanned image based on the calibration data.

[0086] In one embodiment, a medical device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps in the above method embodiments.

[0087] In one embodiment, such as Figure 3 or Figure 4 As shown, the medical device includes two main probes and one backup probe; the medical device is a SPECT-CT device.

[0088] Specifically, the medical device in this embodiment is a dual-probe SPECT-CT device, which includes two main probes (main probe 1 and main probe 2) and one backup probe. During normal scanning, the two main probes are in use, while the backup probe is in a dormant state. Depending on the scanning mode (H-type or L-type scan), the two main probes move according to their relative positions to complete the image scanning procedure. The dual probes can scan simultaneously or alternately, greatly improving examination speed and efficiency, and can perform 180° opposing scans (e.g., ...). Figure 3 (as shown) and 45° scan (as shown) Figure 4 As shown in the figure, this makes the inspection items more flexible and comprehensive.

[0089] The following is a detailed description of the probe switching method when the medical device is a SPECT-CT device, using a specific embodiment. Figure 10 As shown, after the medical device begins scanning, the health monitoring module monitors the current working status of the two main probes in real time to detect any probe malfunctions. If no probe malfunction is detected, the scanning process continues until completion. If a probe malfunction is detected, a probe switching prompt is displayed to determine whether to switch probes. If no probe switching is required, scanning stops and awaits repair. If probe switching is required, the medical device switches the malfunctioning probe to the backup probe, synchronizes the probe status information of the malfunctioning probe to the backup probe, and obtains the relative position information between the backup and normal probes. Based on the relative position information and preset position information, the position error is determined. If the position error is outside the preset error range, the current position of the backup probe is adjusted and the position error is updated. If the position error is within the preset error range, a continue processing interface is displayed to determine whether to rescan or continue scanning. If rescanning is selected, the medical device restarts the scan; if continued scanning is selected, the medical device continues scanning until completion.
