Description

Technical Field

[0001] The present application relates to the field of radiation detection technology, and in particular to a method, terminal and system for detecting radiation in a medical environment. Background Art

[0002] With the continuous development of science and technology, X-rays and CT are being used more and more widely in medical diagnosis. As a result, the number of people undergoing radiation examinations is increasing year by year, and the radiation dose received by the examinees is also increasing accordingly. In the process of exposure to ionizing radiation, if the protective measures are not appropriate and the operating procedures are violated, the dose of radiation received by the human body exceeds a certain limit, which can cause harmful effects. In order to ensure the health of medical staff, the ionizing radiation dose in certain specific places in the hospital needs to be detected and recorded in real time.

[0003] When detecting radiation in a medical environment, each radiation detection terminal is configured to detect radiation in the medical environment at a fixed detection period. However, since the radiation in the medical environment is mainly caused by the beam emitted by medical equipment in the medical environment, when the detection period is set too long, the radiation detection terminal may fail to detect the radiation peak when the medical equipment emits a beam. When the detection period is set too short, maintaining a short detection period will increase the power consumption and loss of the radiation detection terminal, seriously affecting its service life. Summary of the invention

[0004] In order to address the deficiencies in the prior art, the purpose of the present application is to provide a method, terminal and system for detecting radiation in a medical environment, which can accurately capture the radiation peak when the medical device emits a beam without seriously affecting the life of the detection terminal.

[0015] Based on the number of radiometers detected by the radiation detection terminal at the current detection moment, use the first library file to determine whether the medical device has entered a beam-out state; if the determination is no, keep the radiation detection terminal detecting according to the first timing detection cycle; if the determination is yes, configure the radiation detection terminal to continue monitoring according to the second timing detection cycle, and save the number of radiometers detected as peak detection data;

[0016] Based on the number of radiation meters detected by the radiation detection terminal at the current detection moment, the second library file is used to determine whether the medical device has entered the beam stop state.

[0043] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0044] Example 1

[0045] An embodiment of the present application provides a method for detecting radiation in a medical environment, which can accurately capture the radiation peak condition when the medical device emits a beam without seriously affecting the life of the detection terminal.

[0046] Figure 1 This is a flow chart of the method for detecting radiation in a medical environment of the present application. Figure 1 The method for detecting medical environment radiation of the present application is described in detail, including:

[0047] Step S101: In a medical environment to be detected, a radiation detection terminal is used to perform radiation pre-detection to obtain radiation detection training data of the medical equipment in different working states;

[0048] The inventors discovered that medical devices in a medical environment can be divided into four working states: power-off state, beam-waiting state, beam-emitting state, and beam-emitting stopped state: wherein, the beam-waiting state is the state of the medical device from power-on to formal beam-emitting, and the beam-emitting stopped state is the state of the medical device from stopping beam-emitting to power-off; and the medical device being in the beam-emitting state is a turning point of radiation. In order to capture the radiation peak value in the beam-emitting state, the detection cycle of the radiation detection terminal needs to be small enough in the beam-emitting state, while the detection cycle can be large enough at other times.

[0049] Therefore, in order to determine when the medical device enters the beam emitting state and ends the beam emitting state, when the medical device is in the shutdown state and the beam emitting state, the radiation of the medical environment is detected according to the first fixed time detection cycle to obtain the first detection sample data and the second detection sample data;

[0050] When the medical device is in a beam emitting state and a beam emitting stop state, detecting radiation of the medical environment according to a second fixed time detection cycle to obtain third detection sample data and fourth detection sample data;

[0051] It should be noted that the maximum value of the first fixed time detection cycle does not exceed the average beam emission time of the medical device, and the maximum value of the second fixed time detection cycle is less than 1 / 10 of the average beam emission time of the medical device.

[0052] For example, if the average beam emission time of a medical device is 2 seconds, the first timing detection period can be any time not greater than 2 seconds, generally a time between 1 and 2 seconds.

[0053] In this embodiment, the first detection sample data, the second detection sample data, the third detection sample data, and the fourth detection sample data are saved as four CSV format files.

[0054] Step S102: Based on the radiation detection training data, generate a library file for judging the working state of the medical device through training;

[0055] In this embodiment, based on the first detection sample data and the second detection sample data, a first library file is trained and generated for judging whether the medical device has entered the beam-emitting state according to the radiation count value; based on the second detection sample data and the third detection sample data, a second library file is trained and generated for judging whether the medical device has entered the beam-emitting stop state according to the radiation count value.

[0056] In this embodiment, the NanoEdge AI Stidio training library file is used, and the first detection sample data is used as a normal signal, and the second detection sample data is used as an abnormal signal to train and generate the first library file; NanoEdgeAI Stidio is used to take the third detection sample data as a normal signal, and the fourth detection sample data as an abnormal signal to train and generate the second library file.

[0057] Exemplarily, after selecting the chip and signal type corresponding to the radiation detection terminal, the first detection sample data in CSV format is uploaded to NanoEdge AIStidio as regular signals, and the second detection sample data in CSV format is uploaded as abnormal signals. The regular signals and abnormal signals are benchmarked, validated, and simulated to generate a first library file that can be used.

[0058] In some other implementations, other data analysis methods may be used to analyze the first detection sample data, the second detection sample data, the third detection sample data, and the fourth detection sample data to obtain a library file that can be used to determine the working status of the medical device.

[0059] Step S103: Based on the radiation count value detected by the radiation detection terminal and the library file, determine the working state of the medical equipment in the medical environment and configure the detection frequency of the radiation detection terminal corresponding to the working state.

[0060] It is understandable that the first library file and the second library file will be deployed in the control chip of the radiation detection terminal.

[0061] When the radiation detection terminal is deployed in the medical environment, the radiation detection terminal is configured by default to detect radiation in the medical environment according to a first timed detection period, and the number of detected radiation meters is saved as normal detection data;

[0062] Based on the number of radiometers detected by the radiation detection terminal at the current detection moment, use the first library file to determine whether the medical device has entered a beam-out state; if the determination is no, keep the radiation detection terminal detecting according to the first timing detection cycle; if the determination is yes, configure the radiation detection terminal to continue monitoring according to the second timing detection cycle, and save the number of radiometers detected as peak detection data;

[0063] It is understandable that a yes judgment means that the medical device will immediately enter the beam-emitting state, so the detection period of the radiation detection terminal needs to be adjusted to the second timing detection period to capture the peak short-term radiation.

[0064] Based on the number of radiation meters detected by the radiation detection terminal at the current detection moment, the second library file is used to determine whether the medical device has entered the beam stop state. If the judgment is no, the radiation detection terminal is kept detecting according to the second timing detection cycle. If the judgment is yes, the radiation detection terminal is configured to continue monitoring according to the first timing detection cycle.

[0065] It can be understood that when the judgment is yes, it means that the medical device is no longer in the beam-emitting state, and there will be no peak short-term radiation in the medical environment. Therefore, it is no longer necessary to continue monitoring according to the second timing detection cycle of the small time period, and it can be changed to the first timing detection cycle of the large time period to continue monitoring.

[0066] In this implementation, the normal detection data and the peak detection data are also acquired to generate a radiation detection report table.

[0067] Exemplarily, an alarm table is generated, and the peak detection data is compared with the dose equivalent rate alarm value required by the national standard. If the alarm value is exceeded, the polling time, device name, etc. are recorded in the alarm table, and when necessary, it can be queried by time and output as a .CSV file.

[0068] It is understandable that different medical devices have different dose equivalent rate alarm values. For example, when X-ray equipment, CT machines, mammography, breast CBCT, intraoral dental radiography, dental panoramic radiography, dental panoramic cephalography, oral CBCT and whole-body bone densitometers are working, there will be differences in the dose equivalent rate alarm values.

[0069] Example 2

[0070] An embodiment of the present application provides a detection terminal for medical environment radiation, which can accurately capture the radiation peak condition when the medical device emits a beam without seriously affecting the life of the detection terminal.

[0071] Figure 2 This is a schematic diagram of the structure of the medical environment radiation detection terminal of this application, which will be referred to below Figure 2 The medical environment radiation detection terminal of the present application is described in detail, including:

[0072] Radiation detection probe 100;

[0073] The controller 200 is connected to the radiation detection probe 100 and includes:

[0074] The state determination unit 202 is used to determine the working state of the medical equipment in the medical environment using the library file 201 according to the number of radiometers detected by the radiation detection probe 100;

[0075] The detection control unit 203 is connected to the state judgment unit 202 and is used to configure the detection cycle of the radiation detection probe 100 according to the working state;

[0076] The library file 2001 is generated for training radiation detection training data detected by medical equipment in different working states in a medical environment.

[0077] In this embodiment, the radiation detection training data includes:

[0078] The first detection sample data and the second detection sample data are obtained by detecting the radiation of the medical environment according to a first fixed time detection cycle when the medical device is in a shutdown state and a beam-emitting state respectively;

[0079] The third detection sample data and the fourth detection sample data are obtained by detecting the radiation of the medical environment according to the second fixed time detection cycle when the medical device is in the beam emitting state and the beam emitting stop state respectively;

[0080] Among them, the waiting beam state is the state of the medical device from power-on to formal beam emission, the beam-stopping state is the state of the medical device from stopping beam emission to power-off, the maximum value of the first fixed time detection cycle does not exceed the average beam emission time of the medical device, and the maximum value of the second fixed time detection cycle is less than 1 / 10 of the average beam emission time of the medical device.

[0081] In this embodiment, the detection control unit 203 is configured as follows:

[0082] By default, the detection cycle of the radiation detection probe 100 is controlled to be the first fixed-time detection cycle; when the working state is the beam-waiting state, the detection cycle of the radiation detection probe 100 is controlled to be the second fixed-time detection cycle; when the working state is the beam-stopping state, the detection cycle of the radiation detection probe 100 is controlled to be the first fixed-time detection cycle.

[0083] It is understandable that when the medical environment radiation detection terminal is in the first timing detection cycle detection, the power consumption is small, and when it is in the second timing detection cycle detection, the power consumption is large, which affects the service life; because the detection terminal only uses the second timing detection cycle detection when the medical equipment is in the beam-emitting state, and uses the first timing detection cycle detection at other times, the detection terminal can accurately capture and detect the radiation peak without causing too much impact on the service life.
