Method, device, medium and system for generating physical compensator based on 3D printing

Abstract

The invention provides a method for generating a physical compensator based on 3D printing, including the steps of creating a 3D patient model, generating a compensator mold, generating a compensator, creating a 3D patient model through patient body surface data; selecting a compensation area on the 3D patient model, and obtaining compensation The thickness, curved surface and size information of the area are 3D printed to generate a compensator mold; the lead alloy is poured into the compensator mold to generate a compensator; the invention relates to a physical compensator generation system based on 3D printing; the invention also relates to electronic equipment and The readable storage medium is used to execute the method for generating a physical compensator based on 3D printing; the present invention creates a 3D model through the patient's body surface data scanned by a 3D scanner or the patient's medical image data, and uses environmentally friendly materials to 3D print the compensator mold and model The body model does not need to be measured or manufactured manually, which avoids errors caused by human factors. The compensator has high precision and meets the quality control requirements of 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. Background technique [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.

[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
