Physical compensator generating, equipment, medium and system based on 3D printing

Abstract

The invention provides a physical compensator generating method based on 3D printing, wherein the method comprises the following steps of establishing a 3D patient model, generating a compensator moldand generating a compensator, and exactly, the method comprises the following steps: establishing the 3D patient model via patient's body surface data; selecting a compensating area on the 3D patientmodel, acquiring the thickness, curved surface and size information of the compensating area and implementing 3D printing, so as to generate the compensator mold; and casting lead alloy into the compensator mold, so as to generate the compensator. The invention relates to a physical compensator generating system based on 3D printing; the invention also relates to electronic equipment and a readable storage medium, which are used for implementing the physical compensator generating method based on 3D printing; according to the invention, the patient's body surface data or patient's medical image data is scanned via a 3D scanner so as to establish the 3D model; the compensator mold and the mold model are made from environment-friendly materials through 3D printing, and manual measuring or making is avoided, so that errors caused by human factors can be avoided; and the compensator is high in precision and capable of meeting quality control demand in clinical treatment.

Description

technical field [0001] The present invention relates to the technical field of tumor radiotherapy, in particular to a method for generating a physical compensator based on 3D printing, an electronic device, a storage medium and a system.

[0002] The traditional physical compensation method for radiotherapy uses a compensator made by a unified mold or a finished compensator for compensation. In the traditional physical compensation method for radiotherapy, two-dimensional or three-dimensional files are generated according to the data of the treatment planning (TPS) system, and two-dimensional cutting machines are used to Or the three-dimensional cutting machine cuts out the compensator mold on the high-density foam. This method requires high cutting machine precision and material performance. The product production is troublesome and the precision cannot meet clinical requirements. Professional equipment, special ventilation and exhaust are required In the workplace, the lead alloy at high temperature is molded on the foam to cause deformation of the compensator mold and toxic gas. The multi-channel process of compensator mold production requires manual measurement, which is prone to errors, resulting in low precision of the compensator and takes a long time; the finished product The tissue compensation glue is placed directly on the position that needs to be compensated, which has a low degree of adherence to the human body and is easy to slip off, which will cause errors in the later treatment of patients; while the phantom model remains at the theoretical stage due to the differences in patients and cannot be used in practice. use
