Technical Field

The present disclosure relates to the field of radiation dose detection technologies, and in particular, to a radiation dose detection method, device, system, electronic device, and storage medium.

Background

For the treatment of patients in nuclear medicine, for example, thyroid diseases such as hyperthyroidism, thyroid cancer and thyroid cancer, iodine-131 is mainly used for treatment, iodine-131 is used as a radiation element, β rays with the energy of 0.61 mev can be radiated, the physical half-life period is 8.04 days, meanwhile, gamma rays with the energy of 0.365 mev can be radiated, the physical half-life period is 60.14 days, for example, for solid tumors, more iodine-125 implantation technologies are also developed in recent years for treatment, iodine-125 is an orbital electron capture decay nuclide, as a radiation element, gamma rays with the energy of 0.03548 mev can be radiated, and the physical half-life period is 60.14 days.

In the treatment process of a patient in the nuclear medicine department, after a radioactive medicament is injected or orally taken, the patient becomes a living radioactive source, the living radioactive source becomes a movable radioactive source with an unfixed position along the moving track of the patient, and excrement, secretion and the like of the radioactive source have radioactivity. For this reason, it is often necessary to isolate these patients within a dedicated control area to avoid radiation to other people in the surrounding environment. Then how long the patient should be isolated in the control area to leave? In response to this problem, in the prior art, the radiation dose of the residual radiation element in the patient is usually estimated according to the physical half-life of the residual radiation element in the patient, and when the radiation dose of the residual radiation element in the patient is less than the safe radiation dose, the patient can leave the control area. However, since the biological half-cycle also plays a certain auxiliary role in attenuating the radioactive elements, the accuracy of estimating the radiation dose of the residual radioactive elements in the patient by the method is low.

Further, the components shown in fig. 1 may be implemented by software, hardware, or a combination thereof.

Referring to fig. 2, a schematic flowchart of a radiation dose detection method according to an embodiment of the present application is shown, where the method is applied to the electronic device 130 shown in fig. 1. It should be noted that the radiation dose detection method provided in the embodiments of the present application is not limited by the sequence shown in fig. 2 and the following, and the specific flow and steps of the radiation dose detection method are described below with reference to fig. 2.

Step S100, a first radiation dose value detected by a first radiation dose detector is obtained, and the first radiation dose detector is disposed at a chest position of a target user.

In the embodiment of the present application, the first radiation dose detector is disposed at the chest position of the target user, and therefore, the first radiation dose value may be regarded as radiation of all radiation elements remaining in the body of the target user, and the radiation dose value obtained by detection of the first radiation dose detector, and therefore, the first radiation dose value includes radiation of radiation elements remaining in excretory organs such as the large intestine, the bladder, and the like of the target user, and the radiation dose value obtained by detection of the first radiation dose detector. It can be understood that, since the residual radiation elements in the excretory organs such as the large intestine and the bladder of the target user are about to be excreted, the reject dose value is substantially ignored, and based on this, to determine the specific value of the reject dose value, the radiation dose detection method provided in the embodiment of the present application further includes step S200.

Step S200, a second radiation dose value detected by a second radiation dose detector is obtained, and the second radiation dose detector is disposed at the abdomen position of the target user.

In the embodiment of the present application, the second radiation dose detector is disposed at the abdominal position of the target user, and therefore, the second radiation dose value can be regarded as a radiation dose value obtained by detecting radiation elements remaining in excretory organs such as the large intestine and the bladder of the target user. It will also be appreciated that the second radiation dose value will cause a significant disturbance in the estimation of the remaining isolation time, i.e. the second radiation record value will be substantially negligible, since the remaining radiation elements in the excretory organs, such as the large intestine, bladder, etc., of the target user will be expelled from the body.

It should be noted that, since the second radiation dose detector is disposed at the abdomen of the target user and the first radiation dose detector is disposed at the chest of the target user, and the energy radiated by the radiation element remaining in the excretory organs such as the large intestine and the bladder of the target user is attenuated when being radiated from the abdomen to the chest, the reject dose value is necessarily smaller than the second radiation dose value, but the specific numerical value of the reject dose value and the specific numerical value of the second radiation dose value are also necessarily very close to each other.

And step S300, correcting the first radiation dose value according to the second radiation dose value to obtain a first radiation dose estimation value.

According to the description related to step S200, the reject dose value is smaller than the second radiation dose value, but the specific value of the reject dose value is very close to the specific value of the second radiation dose value, so that when the reject dose value is considered to be equal to the second radiation dose value, in the embodiment of the present application, as for step S300, as a first optional implementation manner, it may include: and calculating the difference between the first radiation dose value and the second radiation dose value as a first radiation dose estimated value. Of course, in order to improve the accuracy of the first radiation dose estimation value, in the embodiment of the present application, the dose value may be eliminated according to the second radiation dose value, and in addition, the amount of attenuation generated when the energy radiated by the radiation element remaining in the excretory organs such as the large intestine and the bladder of the target user is radiated from the abdominal position to the chest position is also specifically determined by the distance value between the chest position and the abdominal position and the radiation attenuation coefficient of the radiation element.

Based on the above description, in the embodiment of the present application, as a second optional implementation manner, regarding step S300, step S310, step S320, and step S330 may also be included.

Step S310, combining the posture information of the target user and the characteristic information of the radiation elements in the body of the target user to obtain a first attenuation dose value.

In this embodiment, the posture information of the target user may include height information of the target user, and the characteristic information of the radiation element in the body of the target user includes a radiation attenuation coefficient of the radiation element, where the radiation attenuation coefficient is used to represent a relationship between a radiation distance of the radiation element in the human body and an attenuation amount, for example, to represent a corresponding value of the attenuation amount that increases with each increase of 1CM in the radiation distance. Based on this, in the embodiment of the present application, as a first optional implementation manner, regarding step S310, it may include: and calculating a distance value between the chest position and the abdomen position of the target user according to the height information, extracting a radiation attenuation coefficient of the radiation element from the characteristic information, and combining the distance value and the radiation attenuation coefficient to obtain a first attenuation dose value.

In the specific implementation process of the radiation dose detection method provided by the embodiment of the application, after the height information is obtained, the product of the height information and a preset proportional value can be calculated and used as the distance value between the chest position and the abdomen position of the target user, and the preset proportional value can be the average value of the distance values between the chest positions and the abdomen positions of a plurality of testers, which are counted, relative to the ratio of the height information. In addition, in order to further improve the accuracy of the first radiation dose estimation value, in the embodiment of the present application, a posture image of the target user may also be obtained, and the distance value between the chest position and the abdomen position of the target user is obtained by identifying the posture image.

The distance value between the chest position and the abdomen position of the target user is obtained, and after the radiation attenuation coefficient of the radiation element is extracted from the characteristic information, the distance value and the radiation attenuation coefficient can be combined to obtain a first attenuation dose value. Based on this, it can be understood that, in the embodiment of the present application, the first attenuation dose value may represent an attenuation amount occurring when energy radiated by the radiation element remaining in the excretory organs such as the large intestine and the bladder of the target user is radiated from the abdominal position to the chest position.

Step S320, calculating a difference between the second radiation dose value and the first attenuated dose value as a reject dose value.

It can be understood that, in the embodiment of the present application, the reject dose value may represent the remaining radiation dose after the energy radiated by the residual radiation element in the excretory organs such as the large intestine, the bladder, and the like of the target user is radiated from the abdomen position to the chest position.

Step S330, calculating the difference between the first radiation dose value and the reject dose value as a first radiation dose estimation value.

In the above embodiment, since the first radiation dose value and the second radiation dose value are both directly detected by the radiation dose detector, the accuracy is high, and since the obtained first radiation dose estimated value is the radiation dose estimated value after the reject dose value is ignored, the accuracy is also high.

In addition, it should be noted that the first radiation dose estimation value is a zero-distance radiation value of the target user, but in general, after the target user leaves the control area, other people in the surrounding environment do not contact the target user at a zero distance, but maintain a separation distance of the preset separation value. Based on this, the radiation dose detection method provided in the embodiment of the present application may further include step S400 after step S300 is executed.

And step S400, combining the first radiation dose estimated value and the radiation attenuation coefficient to obtain a second radiation dose estimated value at a position where the distance between the target user and the target user is a preset distance value.

In the embodiment of the present application, after obtaining the first radiation dose estimated value, a second radiation dose estimated value at a position spaced from the target user by a predetermined distance value may be obtained by combining the first radiation dose estimated value and the radiation attenuation coefficient, for example, when the radiation attenuation coefficient is used to represent a corresponding value for increasing the attenuation amount for every 1CM increase of the radiation distance, a product of the predetermined distance value and the radiation attenuation coefficient may be calculated as the second attenuated dose value, and thereafter, a difference between the first radiation dose estimated value and the second attenuated dose value may be calculated as the second radiation dose estimated value at a position spaced from the target user by the predetermined distance value, where the predetermined distance value may be, but is not limited to, 100 CM.

In order to determine how long the target user should be isolated in the control area before leaving, the radiation dose detection method provided in the embodiment of the present application may further include step S500, step S600, and step S700 after step S300.

Step S500, a first estimated curve is created based on N first radiation dose estimated values obtained in a historical detection time period, wherein N is larger than or equal to 2 and is an integer.

In the embodiment of the present application, after the N first radiation dose estimated values obtained in the historical detection period are determined, the N first radiation dose estimated values may be directly approximated to a continuous curve as the first estimated curve by a curve fitting method, and the curve fitting method may be, but is not limited to, an interpolation method, a polishing method, and a least square method. In addition, in the embodiment of the present application, the abscissa of the first prediction curve may be time, and the ordinate may be the first radiation dose estimation value. It should be noted that, in the embodiment of the present application, in order to ensure the reliability of the first prediction curve, the step S500 may also include the step S510 and the step S520.

Step S510, data cleaning is carried out on the N first radiation dose estimated values obtained in the historical detection time period, M target construction values are obtained, M is larger than or equal to 2 and smaller than or equal to N and is an integer.

In this embodiment of the application, the data cleaning may be performed on the N first radiation dose estimated values obtained in the historical detection period, and may be performed by deleting an invalid value from the N first radiation dose estimated values obtained in the historical detection period, where the invalid value may be a first radiation dose estimated value that has a sudden change with respect to two adjacent values, and the two adjacent values include a first radiation dose estimated value that has an obtaining time adjacent to an obtaining time of the invalid value and is located before the obtaining time of the invalid value, and a first radiation dose estimated value that has an obtaining time adjacent to the obtaining time of the invalid value and is located after the obtaining time of the invalid value.

Step S520, a first pre-estimated curve is created based on the M target construction values.

After the M target construction values are determined, the M target construction values may be directly approximated to a continuous curve as a first estimated curve by a curve fitting method, and the curve fitting method may also be, but is not limited to, an interpolation method, a polishing method, and a least square method. In addition, in the embodiment of the present application, the abscissa of the first prediction curve may be time, and the ordinate may be the first radiation dose estimation value.

Step S600, determining a first target time corresponding to the safe radiation dose according to the first pre-estimated curve.

Taking the abscissa of the first prediction curve as time and the ordinate as the first radiation dose estimation value as an example, after the first prediction curve is created, a first coordinate position where the safe radiation dose is located may be determined in the ordinate, and a target position corresponding to the first coordinate position may be determined from the first prediction curve, and thereafter, a second coordinate position corresponding to the target position may be determined in the abscissa as a first target time corresponding to the safe radiation dose, where the safe radiation dose may be set by the medical staff according to the specific type of the radiation element.

Step S700, calculating a difference between the first target time and the current time as the remaining isolation time of the target user.

Through the steps of S500, S600 and S700, the remaining isolation time of the target user can be obtained, so that when a time viewing request sent by the target user through the electronic terminal is received, the remaining isolation time can be sent to the electronic terminal and displayed on the electronic terminal so as to be conveniently viewed by the target user. It should be noted that, in the embodiment of the present application, the electronic terminal may be a smart phone, a tablet computer, a PAD, an MID, or the like, and may also be a first radiation dose detector or a second radiation dose detector disposed on the target user.

In addition, it should be noted that, since the first radiation dose estimation value is a zero-distance radiation value of the target user, but in a normal case, after the target user leaves the control area, other people in the surrounding environment do not contact the target user at a zero distance, but maintain a separation distance of a preset separation distance value, in order to ensure accuracy of the remaining isolation time of the target user, the radiation dose detection method provided in the embodiment of the present application may further include step S800, step S900, and step S1000 after step S400.

Step S800, a second estimated curve is created based on Y second radiation dose estimated values obtained in the historical detection time period, wherein Y is larger than or equal to 2 and is an integer.

In this embodiment, the data cleaning may be performed on Y second radiation dose estimated values obtained in the historical detection period, and may be performed by deleting an invalid value from the Y second radiation dose estimated values obtained in the historical detection period, where the invalid value may be a second radiation dose estimated value that has an abrupt change with respect to two adjacent values, and the two adjacent values include a second radiation dose estimated value that has an obtaining time adjacent to the obtaining time of the invalid value and is located before the obtaining time of the invalid value, and a second radiation dose estimated value that has an obtaining time adjacent to the obtaining time of the invalid value and is located after the obtaining time of the invalid value.

Step S820, a second pre-estimated curve is created based on the Z target construction values.

After the Z target construction values are determined, the Z target construction values may be directly approximated to a continuous curve as a second estimated curve by a curve fitting method, and the curve fitting method may also be, but is not limited to, an interpolation method, a polishing method, and a least square method. In addition, in the embodiment of the present application, the abscissa of the second prediction curve may be time, and the ordinate may be the second radiation dose estimation value.

And S900, determining a second target time corresponding to the safe radiation dose according to the second pre-estimated curve.

Taking the abscissa of the second prediction curve as time and the ordinate as the second radiation dose estimation value as an example, after the second prediction curve is created, the third coordinate position of the safe radiation dose can be determined in the ordinate, the target position corresponding to the first coordinate position is determined from the second prediction curve, and then the fourth coordinate position corresponding to the target position is determined in the abscissa as the second target time corresponding to the safe radiation dose.

Step S1000, calculating a difference between the second target time and the current time as the remaining isolation time of the target user.

Through the steps of S800, S900 and S1000, the remaining isolation time of the target user can be obtained, so that when a time viewing request sent by the target user through the electronic terminal is received, the remaining isolation time can be sent to the electronic terminal and displayed on the electronic terminal so as to be conveniently viewed by the target user.
