[0023] Example 1 Reference Figure 1 and Figure 2 , as a first embodiment of the present invention, a radiotherapy positioning pad is provided, the device comprising: The pad body 100 includes a fixing seat 101, a connecting frame 102 disposed inside the fixing seat 101, and a memory pad 103 disposed inside the connecting frame 102; By placing the patient's head and body on the memory cushion 103, it can provide support; The identification device 200 connected to the pad body 100 includes a body 201, a display panel 202 located on the surface of the body 201, and an identifier 203 disposed below the display panel 202; By using the identification device 200, the patient's identity can be read and the patient information can be output; as well as, The plug wire 300 is used to connect the pad body 100 and the identification device 200 .

[0024] The pad body 100 also includes a pressure detection module 104 and an execution module 105; The pressure detection module 104 is used to collect the pressure on each point of the memory pad 103; The execution module 105 is used to control the memory pad 103 to deform; After the patient lies on the memory pad 103, the built-in pressure detection module 104 can collect the pressure of each part, and the memory pad 103 is divided into multiple groups of independently controlled independent areas. Each group of independent areas is controlled by a brake to achieve deformation control of the memory pad 103.

[0025] The identification device 200 includes a data analysis module 204; The data analysis module 204 is used to receive the data from the pressure detection module 104 and transmit the analyzed data to the execution module 105; The data analysis module 204 is also connected to the database to upload information to the cloud platform; The database cloud service can ensure that patient information can be synchronized through the database when patients seek medical treatment in different hospitals.

[0026] During use, the patient first identifies information through the identifier 203, for example, through face recognition of the patient's facial features, and then reads the corresponding patient data in the database. After successful reading, all patient information is displayed on the display board 202, and the patient information is analyzed and then transmitted to the execution module 105. The execution module 105 controls the memory pad 103 to deform, so that it can better fit the patient's body, making it easier for the doctor to fix the patient.

[0027] Example 2 Reference Figure 3 , which is the second embodiment of the present invention, differs from the first embodiment in that: a method for using a radiotherapy positioning pad is provided, comprising: S1. Collect patient information through the identifier 203.

[0028] The specific steps of the identifier 203 collecting patient information include: Enter patient data and transfer patient data to the database; Compare patient data with the database to determine whether there is existing patient data; When there is patient data in the database, the patient information is displayed through the display panel 202 and the patient is reminded to check the patient information; When patient data does not exist in the database, complete patient information is entered; Among them, the patient data is any data in the patient information, and the patient information includes: facial information, adjustment data, fingerprint information, ID number, medical number, and name.

[0029] Among the patient information, ID number, medical number, adjustment data and name are required information; Among patient information, facial information and fingerprint information are secondary information; When entering patient data, the patient enters their fingerprint or face, and the patient's identity is collected through fingerprint recognition or face recognition; If the collection fails, the patient's identity is collected through the ID number or medical number, and all the patient information is displayed on the display board 202 for patient verification; When the collection is successful, all the patient information is displayed on the display board 202 for patient verification; After successful patient verification, the patient information is transmitted to the data analysis module 204 .

[0030] S2. Analyze the patient information through the data analysis module 204 to obtain recognition results and execution results.

[0031] The steps of analyzing the patient information by the data analysis module 204 include: Determine whether the number of days corresponding to the adjustment data in the patient information is greater than the set value K; When the number of days corresponding to the adjustment data is greater than the set value K, data prediction is performed; When the number of days corresponding to the adjustment data is not greater than the set value K, the output execution result is none; The data prediction step includes: The input date is the forecast date, the N days closest to the forecast date are the core days, and the M days before the core days are the important days; Determine whether the reconciliation data for the core days is missing. If so, the output execution result is None. If not, determine whether the missing data for the important days is less than the threshold Z. If so, perform a secondary prediction. If not, the output execution result is None. In this embodiment, the set value K is 8 days, the core days N is 3 days, and the important days M is 2 days; For example, if today's date is October 10, 2024, and the number of days of adjusted data in the patient information is 10, then it is greater than the set value K, that is, 10 days is greater than 8 days, so data prediction is performed. If the number of days of adjusted data in the patient information is 5, it means that the data is insufficient and effective prediction cannot be performed, so the output execution result is None. When predicting data, today (October 10, 2024) is used as the prediction date, and the three days closest to the prediction date are used as core days, namely October 9, 2024, October 8, 2024, and October 7, 2024. It is determined whether there is any missing adjustment data on these three days. If there is no adjustment data on October 8, 2024, it means that this set of data cannot be effectively predicted, so the output execution result is "None". If the data for these three days is complete and there is no missing data, then a valid prediction can be made. In other words, it is determined whether the missing data on the important days is less than the threshold Z. Assume that the threshold Z is 2, and the dates of the important days M are October 6, 2024 and October 5, 2024. When the number of days with missing data in the important days is less than 2 days, in the case of this embodiment, one of the days is missing or not missing, and a secondary prediction is performed. When the number of days with missing data in the important days is not less than 2 days, in the case of this embodiment, both days are missing, and no effective prediction can be performed, that is, the output execution result is none.

[0032] The steps of the secondary prediction include: A prediction calculation formula is introduced, and predicted adjustment parameters are obtained through the prediction calculation formula, and the predicted adjustment parameters are transmitted to the execution module 105 as execution results.

[0033] The calculation formula is expressed as, ; Where y represents the adjustment parameter of the prediction, Expressed as a number of days, is represented as the intercept, Expressed as the slope, Expressed as the error term; Among them, the slope The calculation formula is expressed as: ; intercept The calculation formula is expressed as: ; Where, Expressed as the mean of days, It is expressed as the parameter mean, n is expressed as the sum of the core days N days and the important days M days; Mean of days The calculation formula is: ; Mean of the parameter The calculation formula is: ; Where, It is the number of the i-th day, It is expressed as the adjustment parameter of day i.

[0034] In the specific implementation process, the adjustment data of the patients in the database are shown in Table 1; Table 1: Patient's adjustment data information table date The first pressure value The second pressure value The third pressure value The fourth pressure value The first block pressure value 2024 / 10 / 1 85 90 100 100 90 2024 / 10 / 2 86 91 101 101 91 2024 / 10 / 3 87 92 102 102 92 2024 / 10 / 4 88 91 102 100 93 2024 / 10 / 5 89 93 103 102 94 2024 / 10 / 6 90 94 104 103 94 2024 / 10 / 7 91 93 104 102 95 2024 / 10 / 8 92 95 105 104 96 2024 / 10 / 9 93 96 105 104 97 First, we need to calculate the mean of the days and parameter mean , taking the first block of pressure values ​​as an example, substitute it into the average value of the days The calculation formula is: ; Substitute into the parameter mean The calculation formula is: ; Then substitute the slope The calculation formula is 1; Then bring in the intercept In the calculation formula, the result is 84; Finally, all the data are put into the prediction calculation formula, and the result is y=94, which means that the prediction result of the first pressure value on the date of 2024 / 10 / 10 is 94; At this point, the output execution result is that the pressure value of the first block is adjusted to 94. According to the same method, the pressure values ​​of all areas are predicted and calculated in turn, and finally the complete execution result is output.

[0035] S3. Determine whether to deform the memory pad 103 based on the recognition result; When the memory pad 103 needs to be deformed, the memory pad 103 is operated to deform through the execution module 105; When the memory pad 103 does not need to be deformed, there is no response; When the memory pad 103 is deformed, the complete execution result will be output, and after the separate brakes in each area of ​​the memory pad 103 receive the corresponding execution result, the deformation of the memory pad 103 is completed, and the patient can then lie directly on the memory pad 103.

[0036] Combined with attachment Figures 1-3 As shown, during each radiotherapy, the pressure on the memory pad is collected and used for the next prediction calculation. The memory pad can also be automatically adjusted according to the prediction results, which can reduce treatment deviations caused by improper posture, thereby reducing potential damage to surrounding healthy tissues. Secondly, it reduces treatment interruptions and repeated treatments caused by manual adjustments, which can make more efficient use of medical resources. In combination with face recognition or fingerprint recognition, the patient only needs to complete the identification of identity information before the operation, and the memory pad adjustment can be automatically completed.
