[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] The probe switching method provided in the embodiment of the present application can be applied to medical equipment with probes. Such as ultrasonic diagnostic equipment, SPECT equipment, SPECT-CT equipment, etc. The following is a detailed description of the SPECT-CT equipment as an example. The imaging principle of CT (Computed Tomography) is that the X-rays emitted by the equipment pass through the human body. Because the density of various organs and tissues in the human body is different, the energy of the rays detected by the probe is also different, resulting in different shadows of various organs in the generated anatomical image. Finally, the data obtained by scanning is processed by a computer to generate a cross-sectional image of the body. The imaging method of SPECT is to inject a single-photon radionuclide imaging agent into the human body. The imaging agent will adhere to specific physiological tissues or lesions, and the rays released by the human imaging agent are collected by the probe to obtain the corresponding image. The SPECT-CT device is a multimodal medical device that combines these two imaging methods. In addition to providing SPECT functional information, it can also provide CT anatomical information. After combining the two, both the anatomical morphology of the lesion and the metabolic status of the lesion can be observed, realizing the complementary advantages of SPECT and CT.

[0027] The specific workflow of the SPECT-CT device is relatively complicated. First, the patient needs to be positioned, during which the patient will be given medication and fixed; then pre-scanning planning is performed, during which the range of the patient's examination part needs to be planned and the scanning range needs to be input into the device; finally, scanning and reconstruction are performed. During the operation of the equipment, the probe of the SPECT-CT may move differently due to different scanning parts, which facilitates the probe to scan the scanning part. After the scan is completed, the image is confirmed and the patient is released. During the operation of the existing SPECT-CT, if the probe fails, the scanning service will be interrupted. In this case, the only thing to do is to wait for maintenance personnel to repair the equipment. This process will consume huge manpower and material resources, and will affect the operating efficiency of the equipment and the normal operation of the hospital, causing inconvenience to the patient's diagnosis and treatment plan.

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

[0029] In one embodiment, Figure 1As shown, a probe switching method is provided, which is described by taking the application of the method to a medical device as an example, and includes the following steps:

[0030] Step S110 , responding to the probe switching instruction to switch the probe to be switched to the standby probe.

[0031] Specifically, in the medical device of the embodiment of the present application, according to the action classification of the probe, at least three types of probes are included: 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. The normal probe is a probe that can work normally without switching. For the convenience of description, the following description is based on an example in which the number of probes of each type is one.

[0032] After receiving the probe switching command, the medical device will switch the probe to be switched to the standby probe, that is, the medical device responds to the probe switching command, removes the probe to be switched through the rack, and moves the standby probe to the position of the probe to be switched. The standby probe has the same function as the probe to be switched, so that the corresponding medical examination items can still be performed after the switch. The probe switching command can be triggered by a variety of situations, such as failure of the probe to be switched, the need to actively replace it with a standby probe, etc.

[0033] Step S120, synchronizing 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 standby probe, it sends the probe status information of the probe to be switched to the controller of the standby probe to synchronize the status information of the standby probe. The probe status information of the probe to be switched includes the probe posture and probe scanning parameters. The probe posture is the pitch angle, yaw angle and roll angle of the probe relative to the medical device; the probe scanning parameters are parameters used to set the scanning mode. After the medical device obtains the probe switching instruction, it will save a snapshot of the probe status information of the probe to be switched for use in data synchronization. Through the synchronization of the probe status information, it can be ensured that the standby probe can seamlessly take over the work of the probe to be switched, and continue to scan according to the same parameters and posture, thereby maintaining the continuity and consistency of the scanning data.

[0035] Step S130, obtaining relative position information between the standby probe and the normal probe.

[0036] Specifically, after the medical device switches the probe to be switched to the spare probe, it is also necessary to calibrate the position of the spare probe to ensure the accuracy of the position of the spare probe. When the spare probe moves to the position of the probe to be switched, the medical device needs to obtain the relative position information between the spare probe and the normal probe. The relative position information can be detected by a sensor or calculated by a positioning module in the medical device. In some embodiments, since the medical device needs to control the movement of the probe, the absolute position information of the probe relative to the medical device can be obtained in real time. When the relative position information needs to be obtained, the relative position information between the spare probe and the normal probe can be calculated by respectively obtaining the absolute position information of the spare probe and the normal probe.

[0037] Step S140, determining a position error based on the relative position information and the preset position information.

[0038] Specifically, after the medical device obtains the relative position information between the standby probe and the normal probe, the position error is determined based on the relative position information and the preset position information. The preset position information is the relative position information between the probe to be switched and the normal probe, which is preset under normal working conditions. It can be understood that a position information of the normal probe corresponds to a position information of the probe to be switched, and also corresponds to a relative position information between the two probes, which can be stored in the medical device in the form of a data table. When the current position information of the normal probe is determined, the current preset position information can be determined. The position error can be determined by calculating the error between the relative position information and the preset position information.

[0039] Step S150, adjusting the current position of the standby probe based on the position error and updating the position error until the position error is within a preset error range.

[0040] Specifically, after the medical device determines the position error, it adjusts the current position of the standby probe according to the size of the position error, recalculates the relative position information between the standby probe and the normal probe after the position adjustment, and then recalculates and updates the position error until the position error is within the preset error range. The smaller the position error, the more the current position of the standby probe meets the preset position requirement. When it is judged that the position error is within the preset error range, it means that the current position of the standby probe meets the position error requirement of the medical device and can meet the continuity requirement of the device scanning. At this time, the entire probe switching step is completed.

[0041] The above-mentioned probe switching method switches the probe to be switched to the standby probe in response to the probe switching instruction, and then synchronizes the probe status information of the probe to be switched to the standby probe, so that the standby probe can be adjusted to the probe posture and probe scanning parameters of the probe to be switched. Then the relative position information between the standby probe and the normal probe is obtained, and the position error is determined based on the relative position information and the preset position information. Finally, the current position of the standby 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 switched standby probe can be accurately adjusted to the position before the switch of the probe to be switched, so that the standby probe can continue to perform subsequent medical examination items without waiting for maintenance personnel to perform maintenance, thereby improving the operating efficiency of medical equipment and preventing inconvenience to the patient's diagnosis and treatment plan.

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

[0043] Step S111, obtaining the switching position information of the probe to be switched and the standby position information of the standby probe.

[0044] Specifically, in this embodiment, when the probe to be switched is switched to the standby probe, the medical device first obtains the current position information of the probe to be switched, that is, the switching position information. At the same time, the current position information of the standby probe is obtained, that is, the standby position information. In some embodiments, when the medical device is working, the switching position information of the probe to be switched will continue to change, and the standby probe will also move with the movement of the probe to be switched, so the standby position information will also continue to change.

[0045] Specific examples, such as Figure 3 As shown in the figure, in one embodiment, when the scanning mode of the medical device is the H-type scanning mode, the positions of the three probes are distributed, the two main probes are symmetrically arranged at 180°, and the spare probe is arranged at a position with a 90° angle with the main probe. When the medical device is working, the three probes will rotate around the treatment bed at the same time, thereby performing 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 spare position information of the spare probe. Figure 4As shown in the figure, in one embodiment, when the scanning mode of the medical device is the L-shaped scanning mode, the positions of the three probes are distributed, the two main probes are set at an angle of 90°, and the spare probe is set at a position with an angle of 135° to the main probe. When the medical device is working, the three probes will rotate around the treatment bed at the same time 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 spare position information of the spare probe.

[0046] Step S112: moving the standby probe based on the switching position information, and moving the probe to be switched based on the standby position information.

[0047] Specifically, after the medical device obtains the switching position information of the probe to be switched and the standby position information of the standby probe, the standby probe is moved according to the switching position information of the probe to be switched to move the standby probe to the position of the probe to be switched. At the same time, the probe to be switched is moved according to the standby position information of the standby probe to move the probe to be switched to the position of the standby probe, thereby completing the switching between the probe to be switched and the standby probe. In some other embodiments, the probe to be switched may not be moved to the position of the standby probe, but the probe is moved according to a preset position information so that the probe to be switched leaves the current position.

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

[0049] Step S160, monitoring the current working status of all probes.

[0050] Specifically, the medical device in this embodiment determines whether to switch the probe according to the working state of the probe. The medical device monitors the current working state of all probes in real time through the set health monitoring module. When the probe works normally, the working state is normal; when the probe fails, the working state is faulty. It can be understood that the standby probe is generally in standby state, and only when the probe needs to be switched, the standby probe will be awakened to execute the above-mentioned probe switching method.

[0051] Step S170: The probe whose current working state is a fault state is used as the probe to be switched.

[0052] Specifically, when the medical device is monitoring the current working status of all probes, if it is found that there is a probe whose current working status is a faulty status, it will be used as a probe to be switched, and then the probe to be switched will be switched through subsequent probe switching steps. It can be understood that the number of probes to be switched is generally one, so the number of spare probes is generally also set to one. In some other embodiments, the number of probes to be switched can also be multiple, and correspondingly, the number of spare probes is also multiple, and the number of probes to be switched is less than or equal to the number of spare probes.

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

[0054] Step S180, when it is detected that there is a probe whose current working state is a fault state, a probe switching prompt interface is displayed.

[0055] Specifically, in this embodiment, when the medical device is monitoring the current working status of all probes, if it detects that there is a probe whose current working status is a faulty status, that is, when it detects that there is at least one probe whose current working status is a faulty status, the medical device will display a probe switching prompt interface on the user interaction interface. The probe switching prompt interface is used to indicate to the user that there is a faulty probe that needs to be switched, and the probe switching instruction can be obtained through the probe switching prompt interface. The probe switching prompt interface includes: a switch probe button and a non-switch probe button. The switch probe button is used to trigger the probe switching instruction. The medical device responds to the probe switching instruction to switch the probe to be switched to a standby probe; after the user triggers the non-switch probe button, the medical device will stop working to wait for maintenance personnel to repair the faulty probe.

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

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

[0058] Specifically, in this embodiment, after the medical device adjusts the current position of the standby probe based on the position error, it will recalculate and update the position error until the position error is within the preset error range. When the position error is within the preset error range, the medical device will display a continue processing interface on the user interaction interface, and the display of the continue processing interface is used to instruct the user on the subsequent processing method. The continue processing interface includes: a rescan button and a continue scanning button. After the user triggers the rescan button, the medical device will re-execute the current medical examination item to re-scan through the standby probe; after the user triggers the continue scanning button, the medical device will continue to execute the current medical examination item to continue scanning through the standby probe. Since the errors between the position information and probe status information of the standby probe and the probe to be switched are within the allowable error range, accurate scanning data can be obtained by continuing to execute subsequent scanning tasks through the standby probe, thereby completing the supplementary scan.

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

[0060] Step S200 , responding to the probe scanning instruction to scan through the standby probe and the normal probe to obtain scanning data.

[0061] Specifically, after the medical device displays the continue processing interface on the user interaction interface, the corresponding probe scanning instruction can be obtained through the user's triggering action. The probe scanning instruction includes: a rescan instruction and a continue scanning instruction. The rescan instruction is obtained after being triggered by the rescan button, and the continue scanning instruction is obtained after being triggered by the continue scanning button. After receiving the rescan instruction, the medical device re-scans through the spare probe and the normal probe; after receiving the continue scanning instruction, the medical device continues to scan through the spare probe and the normal probe. During the probe scanning process, corresponding scanning data will be obtained.

[0062] Step S210, correcting the scanned data based on the position error to obtain corrected data.

[0063] Specifically, during the scanning process of the medical device, since there is still a certain error in the position of the adjusted spare probe, the medical device will correct the scan data based on the position error through a correction algorithm. The correction algorithm can make corresponding adjustments or compensations to the scan data according to the deviation between the actual position and the theoretical position of the spare probe to compensate for the image distortion or artifacts caused by the position error of the spare probe, thereby obtaining the corrected correction data. The correction algorithm can include a variety of methods such as linear interpolation, nonlinear transformation, and iterative reconstruction.

[0064] Step S220: determining a scanned image based on the correction data.

[0065] Specifically, the medical device corrects the original scan data to obtain corresponding correction data, and then uses the corrected correction data to generate the final scan image through an image reconstruction algorithm. Different types of medical devices have different image reconstruction processes. Through the data correction step of this embodiment, the correction data can more accurately reflect the true shape and position information of the scanned object, reducing image distortion or artifacts caused by the position error of the probe.

[0066] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0086] In one embodiment, a medical device is provided, including a memory and a processor, wherein a computer program is stored in the memory, and the processor implements the steps in the above-mentioned method embodiments when executing the computer program.

[0087] In one embodiment, Figure 3 or Figure 4 As shown, the medical device includes two main probes and one spare probe, and 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 a spare probe. During the normal scanning process of the medical device, the two main probes are in use and the spare probe is in a dormant state. The two main probes move accordingly based on the relative positions of the probes according to the different scanning modes (H-type scanning or L-type scanning) to complete the image scanning procedure. The dual probes can scan simultaneously or alternately, greatly improving the inspection speed and efficiency, and can perform 180° opposite scanning (such as Figure 3 ) and 45° scanning (as shown Figure 4 The inspection items are more flexible and comprehensive.

[0089] The following is a detailed description of the specific steps of the probe switching method when the medical device is a SPECT-CT device. Fig.10 As shown, after the medical device starts scanning, the health monitoring module is used to monitor the current working status of the two main probes in real time to monitor whether the probes are faulty. If no probe fault is detected, the scanning process continues until the scan is completed; if a probe fault is detected, the probe switching prompt interface is displayed to determine whether to switch the probe. If the probe is not switched, the scanning is stopped and maintenance is waited for; if the probe is switched, the medical device switches the faulty probe to be switched to the spare probe, and then synchronizes the probe status information of the probe to be switched to the spare probe, and obtains the relative position information between the spare probe and the normal probe, and determines the position error based on the relative position information and the preset position information. When it is determined that the position error is not within the preset error range, the current position of the spare probe is adjusted and the position error is updated; when it is determined that the position error is within the preset error range, the continue processing interface is displayed to determine whether to rescan or continue scanning. When it is determined to be a rescan, the medical device restarts the scan; when it is determined to be a continued scan, the medical device continues to scan until the scan is completed.
