Description

Technical Field

[0001] This application relates to the technical field of medical devices, for example, to a method for controlling a radiation source and a medical device. Background Art

[0002] Currently, in hospitals, doctors race against time to rescue patients' lives with the help of medical devices or find ways to complete treatment surgeries in the shortest possible time. During this process, doctors hope that medical devices can assist in treatment as efficiently as possible. In medical devices, how the radiation source can quickly respond to radiation emission instructions, such as how an X-ray tube can quickly respond to an X-ray emission instruction, has become a hot research issue. The medical device can be a Digital Subtraction Angiography (DSA) device.

[0003] In the related art, before an X-ray tube emits X-rays, it is necessary to first look up the corresponding filament preheating current value according to the exposure parameters, and then preheat the target filament to make the temperature of the target filament reach a preset target value. By increasing the filament preheating current value, the filament preheating time can be reduced, and then the next X-ray emission process can be carried out.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] The increase in the filament preheating current value needs to be based on the characteristics of the filament itself, so it will be limited within a certain range, and still cannot well shorten the beam output time of the X-ray tube.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0015] Optionally, cooling down the target filament includes: setting at least one second intermediate temperature; sequentially cooling down the target filament based on at least one second intermediate temperature; wherein, before cooling down at each second intermediate temperature, it is determined that the target exposure mode is not triggered.

[0016] Optionally, the method for controlling the radiation source further includes: determining the cooling rate of the target filament during the staged cooling process according to the triggering frequency of the target exposure mode in the remaining operation process; wherein, the higher the triggering frequency of the target exposure mode in the remaining operation process, the slower the cooling rate of the target filament during the staged cooling process.

[0017] Optionally, the method for controlling the radiation source further includes: when the actual exposure mode is different from the predicted target exposure mode, adjusting the temperature of the target filament from the current temperature to the temperature corresponding to the actual exposure mode; or, when the actual exposure mode is different from the predicted target exposure mode, preheating the filament corresponding to the actual exposure mode and cooling down the target filament corresponding to the predicted target exposure mode.

[0035] Combined with Figure 1 As shown, the embodiments of the present disclosure provide a method for controlling a radiation source. The execution subject of the method can be a processor, and the method includes:

[0036] S101, the processor predicts the operation process of the exposure mode corresponding to the current surgical type based on a preset data model.

[0037] S102, the processor determines the target temperature of the target filament according to the target exposure mode in the operation process.

[0038] S103, the processor preheats the target filament according to the target temperature before the target exposure mode is triggered.

[0039] In the embodiments of the present disclosure, by using a preset data model, it is possible to predict the set of possible exposure modes, i.e., the operation process, of the current surgery. According to the target exposure mode in the predicted operation process, the target temperature of the target filament to be used in the radiation source is determined. Before the target exposure mode is triggered, preheating the target filament according to the target temperature can more precisely control the temperature of the filament, reduce energy waste, and extend the service life of the filament. By preheating the target filament in advance before the target exposure mode is triggered, the target filament can reach the target temperature faster when responding to the target exposure mode, so as to quickly proceed to the next radiation emission process, shortening the beam output time of the radiation source.

[0040] Optionally, the data model is constructed as follows: Obtain the operation processes of the exposure modes corresponding to different surgical types, and the exposure time intervals of the exposure modes; convert the exposure modes and exposure time intervals into sequence data; train the initial model according to the sequence data to obtain the trained data model.

[0041] In this embodiment, different surgical types will have corresponding main exposure modes. During a surgery, one or more exposure modes need to be triggered according to the surgical type, and the same exposure mode may also need to be triggered once or multiple times. Combining Figure 2 As shown, during a surgery, at the beginning of the surgery, the trigger frequency of the exposure mode is relatively low. As the surgery progresses, the trigger frequency of the exposure mode becomes higher and higher. As the surgery ends, the trigger frequency of the exposure mode will gradually decrease again. It can be understood that the higher the trigger frequency of the exposure mode, the smaller the exposure time interval, and the lower the trigger frequency of the exposure mode, the larger the exposure time interval. The data model can predict the exposure modes to be triggered during the current surgery and their corresponding exposure time points according to the current surgical type. According to the exposure time points, the trigger timing of the exposure mode can be determined. Therefore, for the construction of the data model, it is necessary to obtain the exposure modes commonly used for different surgical types, as well as the operation frequencies and exposure time points of different exposure modes in a surgical type. The exposure time interval can be calculated according to the exposure time points of two adjacent exposure modes. Then convert the exposure modes and exposure time intervals into sequence data that can be better understood by the initial model, and finally train the initial model to obtain the required data model. In one example, the initial model can include a self-attention structure based on the Transformer model, and of course, it can also include a CNN or RNN structure.

[0042] Optionally, through the existing operation behavior logs in the hospital, obtain the exposure modes corresponding to different surgical types, and the exposure time intervals of the exposure modes. The exposure time interval can also be modified and adjusted according to the actual operation data of the doctor.

[0043] In this embodiment, during a surgical procedure, the doctor can control the medical device to perform exposure through a foot pedal. For example, each time the doctor steps on the foot pedal, an exposure mode is triggered, and based on the time interval between two adjacent steps on the foot pedal, the exposure time interval can be determined. By performing big data training on the existing operation records in the hospital, the data model can achieve more accurate prediction of the exposure mode, thereby reducing the filament loss and the usage cost of the medical device. It can also accumulate exposure operation data for different surgical types, providing value in medical experience for the training process.

[0044] Optionally, in a specific embodiment, the operation process of the exposure mode corresponding to a surgical type includes three different exposure modes A, B, and C. When performing the surgery corresponding to this surgical type, the operation process of the corresponding exposure mode is: (A, A, A, A, B, C, C, B, C, B, A), and the exposure time intervals between adjacent two exposure modes are successively: (T1, T2, T3, T4, T5, T6, T7, T8, T9, T10). According to this operation process of the exposure mode and the exposure time intervals, sequence data can be obtained: (A, T1, A, T2, A, T3, A, T4, B, T5, C, T6, C, T7, B, T8, C, T9, B, T10, A). For multiple different surgical types, a corresponding set of sequence data can be obtained. All the sequence data is input into the initial model, and parallel training is performed using the self-attention structure of the Transformer model. By given the surgical type, the operation process of the exposure mode and the exposure time intervals under this surgical type are predicted by the model. The prediction results are compared with the actual sequence data, and the model parameters are modified to control the prediction error, such as controlling the time error within 0.5 s to improve the prediction results of the model. It should be noted that the three different exposure modes A, B, and C can correspond to different focal spot sizes of the radiation source. For example, A corresponds to the large focal spot, B corresponds to the small focal spot, and C corresponds to the micro focal spot. Different focal spot sizes correspond to different filaments. For the case including the three exposure modes A, B, and C, three filaments can be included, and each filament can have different filament characteristics. The three different exposure modes A, B, and C can correspond to different exposure parameters under the same filament of the radiation source, such as tube voltage, tube current, and shooting angle, etc. Preheating is an overall overview of adjusting the filament temperature, which can be a temperature increase situation or a temperature decrease situation. For the same target filament, during the switching process between the two exposure modes A and B, if the filament temperature in the A exposure mode is higher than that in the B exposure mode, then the preheating can be a temperature increase process; if the filament temperature in the A exposure mode is lower than that in the B exposure mode, then the preheating can be a temperature decrease process.

[0045] Optionally, the current surgical type is determined according to the patient information input by the user.

[0046] In this embodiment, during the operation, the user (doctor) will first start the medical device system, including software and related hardware. Then the user will create patient information in the software system and input the surgical organ and surgical type of the patient. According to the input surgical type, the data model can predict the operation process of the exposure mode and the corresponding exposure time points during the next operation process.

[0047] Optionally, determining the target temperature of the target filament according to the target exposure mode in the operation process includes: determining the tube current and tube voltage of the radiation source according to the target exposure mode; based on the emission characteristics of the target filament, determining the preheating current value of the target filament according to the tube current and tube voltage; and determining the target temperature of the target filament according to the preheating current value.

[0048] In this embodiment, it is necessary to first determine a target exposure mode among multiple exposure modes in the operation process. Different exposure modes correspond to different image quality requirements and ray penetration depths. For each target exposure mode, determine the required radiation source parameters, including tube current and tube voltage. The tube current affects the intensity of the ray, that is, the number of electrons passing through the radiation source per unit time. The tube voltage affects the energy of the ray, that is, the energy level of the ray generated when electrons strike the anode target. According to the target exposure mode and the technical specifications of the radiation source, select a suitable target filament. Different filaments have different characteristics, such as emission efficiency and lifespan. Based on the emission characteristics of the target filament, calculate the preheating current value required to reach the required tube current and tube voltage. According to the preheating current value and the physical characteristics of the filament, determine the target temperature of the target filament. This temperature is the working temperature that the filament needs to reach during exposure to ensure the effective emission of rays.

[0049] Optionally, preheating the target filament according to the target temperature includes: determining at least one first intermediate temperature according to the target temperature; preheating the target filament based on the at least one first intermediate temperature and the target temperature; wherein, before performing the preheating at each first intermediate temperature, it is determined that the target exposure mode has not been triggered.

[0050] In this embodiment, according to the prediction result of the data model, it is necessary to complete the preheating of the target filament before the exposure time point corresponding to the target exposure mode arrives, so that the target filament can quickly reach the target temperature when the target exposure mode is triggered. The preheating of the target filament can be set to a staged heating mode. According to different hospitals, different surgical types, and different filament conditions, configure different numbers of stages, the first intermediate temperature of each stage, and the time interval between two stages. It is also possible to adjust the heating time of each stage through different preheating current values for different filaments. If the operation is over, the filament will no longer be preheated.

[0051] Optionally, taking the preheating of the target filament in three stages as an example, the target filament is preheated according to the target temperature, including: heating the temperature of the target filament to a first temperature; after a first duration and when the target exposure mode is not triggered, heating the temperature of the target filament from the first temperature to a second temperature; after a second duration and when the target exposure mode is not triggered, heating the temperature of the target filament from the second temperature to a third temperature; wherein, the first temperature is less than the second temperature, the second temperature is less than the third temperature, and the third temperature is less than the target temperature.

[0052] In this embodiment, as shown in Figure 3 the first stage: heating the temperature of the target filament to a first temperature. The purpose of the first stage is to start preheating the filament, but avoid damaging the filament due to overheating. The second stage: after a first duration t1 and when the target exposure mode is not triggered, heating the temperature of the target filament from the first temperature to a second temperature. The purpose of the second stage is to further preheat the filament in preparation for a possible upcoming exposure. The third stage: after a second duration t2 and when the target exposure mode is not triggered, heating the temperature of the target filament from the second temperature to a third temperature. The purpose of the third stage is to bring the filament closer to the target temperature. The method of staged heating can reduce energy waste and allow the system to adjust the heating strategy according to the actual triggering situation of the exposure mode. By gradually heating, the thermal stress generated by the filament due to sudden temperature changes can also be reduced, thereby extending the service life of the filament.

[0053] Optionally, the method for controlling the radiation source further includes: when the target exposure mode is triggered, raising the temperature of the target filament from the current temperature to the target temperature.

[0054] In one embodiment, during the preheating process of the filament, the target temperature is not taken as the final goal of preheating. Instead, after the target exposure mode is triggered, the temperature of the target filament is raised from the current temperature to the target temperature. Since both the target filament and the target temperature are predicted based on a data model, for possible prediction errors, the target filament is not heated to the target temperature during the preheating process. This can reduce the situation where the target filament is heated to the target temperature but then not needed, thus ensuring the filament life. After raising the temperature of the target filament from the current temperature to the target temperature, the subsequent radiation emission process can be carried out.

[0055] Optionally, the first temperature is [20%, 30%] of the target temperature.

[0056] Optionally, the second temperature is [50%, 60%] of the target temperature.

[0057] Optionally, the third temperature is [70%, 80%] of the target temperature.

[0058] In another embodiment, the target exposure mode is triggered in advance, so that there is no need to perform multi-stage preheating. In response to the instruction that the target exposure mode is triggered, the temperature is directly increased from the current temperature to the target temperature.

[0059] Optionally, the method for controlling the radiation source further includes: after preheating the target filament according to the target temperature, if the target exposure mode has not been triggered after a preset duration, the target filament is cooled down.

[0060] Combined with Figure 4 As shown in the figure, another method for controlling a radiation source provided by an embodiment of the present disclosure includes:

[0061] S401, the processor predicts the operation process of the exposure mode corresponding to the current surgical type based on a preset data model.

[0062] S402, the processor determines the target temperature of the target filament according to the target exposure mode in the operation process.

[0063] S403, the processor preheats the target filament according to the target temperature before the target exposure mode is triggered.

[0064] S404, the processor determines whether the target exposure mode is triggered within a preset duration. If so, S405 is executed; if not, S406 is executed.

[0065] S405, the processor increases the temperature of the target filament from the current temperature to the target temperature.

[0066] S406, the processor cools down the target filament after a preset duration.

[0067] In this embodiment, when the prediction model makes a prediction error, it may occur that when the exposure time point corresponding to the target exposure mode arrives and after a preset duration, the target exposure mode has not been triggered yet. For example: the data model predicts that an exposure mode will be triggered after 30s, but it is not triggered after 30s; or the data model predicts that the next triggered exposure mode is A, but the actually triggered exposure mode is B. At this time, it is necessary to cool down the target filament to reduce filament loss.

[0068] Optionally, cooling down the target filament includes: setting at least one second intermediate temperature; sequentially cooling down the target filament based on at least one second intermediate temperature; wherein, before cooling down at each second intermediate temperature, it is determined that the target exposure mode has not been triggered.

[0069] In this embodiment, the cooling of the target filament can also be set to a mode of staged cooling. According to different hospitals, different surgical types, and different filament conditions, different numbers of stages can be configured, as well as the second intermediate temperature of each stage and the time interval between two stages. For different filaments, the cooling time of each stage can also be adjusted by different current values. If the surgery is over, the current value of the filament is directly set to the current value during the static period to minimize the filament current to the greatest extent.

[0070] Optionally, taking the cooling of the target filament in three stages as an example, the cooling of the target filament includes: when the third duration has passed and the target exposure mode is not triggered, cooling the temperature of the target filament from the third temperature to the fourth temperature; when the fourth duration has passed and the target exposure mode is not triggered, cooling the temperature of the target filament from the fourth temperature to the fifth temperature; when the fifth duration has passed and the target exposure mode is not triggered, cooling the temperature of the target filament from the fifth temperature to the sixth temperature; where the sixth temperature is less than the fifth temperature, the fifth temperature is less than the fourth temperature, and the fourth temperature is less than the third temperature.

[0071] In this embodiment, in combination with Figure 5 As shown, the first stage: when the third duration t3 has passed and the target exposure mode is not triggered, cooling the temperature of the target filament from the third temperature to the fourth temperature. The second stage: when the fourth duration t4 has passed and the target exposure mode is not triggered, cooling the temperature of the target filament from the fourth temperature to the fifth temperature. The third stage: when the fifth duration t5 has passed and the target exposure mode is not triggered, cooling the temperature of the target filament from the fifth temperature to the sixth temperature. The method of staged cooling helps to save energy, allows the system to adjust the temperature of the filament according to actual needs, and reduces unnecessary energy consumption. Gradual cooling also helps to protect the filament, avoid damage caused by sudden temperature changes, and extend the service life of the filament. Ensuring that the filament gradually cools down when the exposure mode is not triggered can avoid overheating problems caused by maintaining a high temperature for a long time, and improve the safety and reliability of the system.

[0072] Optionally, the fourth temperature is [55%, 65%] of the target temperature.

[0073] Optionally, the fifth temperature is [35%, 45%] of the target temperature.

[0074] Optionally, the sixth temperature is [15%, 25%] of the target temperature.

[0075] Optionally, the method for controlling the radiation source further includes: determining the cooling rate during the staged cooling process of the target filament according to the triggering frequency of the target exposure mode in the remaining operation process; wherein, the higher the triggering frequency of the target exposure mode in the remaining operation process, the slower the cooling rate during the staged cooling process of the target filament.

[0076] In this embodiment, when cooling the target filament, it is also necessary to consider the usage of the filament in the subsequent operation process. If the triggering frequency of the target exposure mode in the remaining operation process is relatively high, such as the target exposure mode will be triggered soon, at this time, the target filament can be cooled slightly, for example, first cooled by 5% and then cooled by 10%. If the triggering frequency of the target exposure mode in the remaining operation process is relatively low, then rapid cooling of the temperature of the target filament can be considered.

[0077] Optionally, the method for controlling the radiation source further includes: when the actual exposure mode is different from the predicted target exposure mode, adjusting the temperature of the target filament from the current temperature to the temperature corresponding to the actual exposure mode; or, when the actual exposure mode is different from the predicted target exposure mode, preheating the filament corresponding to the actual exposure mode and cooling the target filament corresponding to the predicted target exposure mode.

[0078] In this embodiment, when the actual exposure mode is different from the predicted target exposure mode, it is necessary to heat the filament required by the actual exposure mode in time to ensure the correct triggering of the actual exposure mode. In addition, when the filament corresponding to the actual exposure mode is different from the target filament corresponding to the target exposure mode, it is also necessary to cool the target filament to protect the target filament.

[0079] Optionally, the method for controlling the radiation source further includes: at the beginning of the operation, heating all the filaments in the radiation source in stages.

[0080] In this embodiment, by heating all the filaments in stages during the idle period of the filaments, it can be ensured that when the target exposure mode is triggered, the target filament corresponding to the target exposure mode has completed preheating, so as to quickly reach the working temperature and reduce the beam output time of the radiation source.
