Problems solved by technology
[0003] However, the radiotherapy linear accelerator equipment is different, and the system hardware parameters of two linear accelerators from different manufacturers are different. Even for the same patient, the radiotherapy plans obtained are different.
Therefore, different patients, radiotherapy plans obtained on different linear accelerator equipment cannot learn from each other
In addition, even if the tumor location and tumor area are the same, the radiotherapy plans cannot be used for mutual reference due to the different body shapes of the patients.
In this way, in the process of searching for historical radiotherapy cases, similar historical radiotherapy plans may be missed, resulting in low utilization of historical radiotherapy planning resources, and the accuracy of the current radiotherapy plan is relatively low

The device includes: an acquisition unit, configured to acquire a CT image of a patient to be radiotherapy; a processing unit, configured to determine a registration matrix according to the CT image and a preset CT image template; a processing unit, configured to determine a registration matrix according to the registration Registering the first mask image with the alignment matrix to obtain a third mask image, and registering the second mask image according to the registration matrix to obtain a fourth mask image, the first mask image The film map is used to indicate the planned target area of the patient to be radiotherapy, and the second mask map is used to indicate the area of the organ at risk of the patient to be radiotherapy; the processing unit is also used to and the fourth mask map, determining a target historical radiotherapy plan corresponding to the patient to be radiotherapy; a processing unit, further configured to formulate a radiotherapy plan for the patient to be radiotherapy according to the target historical radiotherapy plan.
Description
technical field [0001] The present application relates to the technical field of image recognition, and in particular to a radiotherapy plan formulation device, method and storage medium. Background technique [0002] In the process of formulating a radiotherapy plan, a radiotherapy physicist will send a newly arrived case into the database for search, search for a matching historical radiotherapy plan, and then compile the relevant parameters of the matched historical radiotherapy plan, such as radiotherapy dose and The type of radiotherapy is input into the treatment planning system (Treatment Planning System, TPS), TPS will optimize the current radiotherapy case according to these parameters, and formulate a radiotherapy plan for this newly arrived case. [0003] However, the radiotherapy linear accelerator equipment is different, and the system hardware parameters of two linear accelerators from different manufacturers are different. Even for the same patient, the radiot...
