Embodiment Construction

[0021] like figure 1 A method for implementing radiotherapy plan transplantation on the Pinnacle treatment planning system shown, including a three-dimensional acquisition subsystem, a point cloud basic processing subsystem, and a real-time registration subsystem;

[0022] The 3D acquisition subsystem uses a laser speckle system and a high-precision color camera to obtain the original 3D point cloud data, specifically: using laser speckle structured light to obtain patient depth information, that is, 3D information, and using a color camera to obtain the color of the measured object information;

[0023] The cloud basic processing subsystem adopts the FPGA module and the DSP module to automatically adjust the human body direction and denoise the point cloud to obtain the three-dimensional point cloud human body surface contour, specifically: using the basic FPGA and DSP front-end point cloud processing system to obtain the complete Three-dimensional information, fusion of col...

Abstract

The invention relates to a method for realizing radiotherapy plan transplantation on a Pinnacle treatment plan system, which comprises a three-dimensional acquisition subsystem, a point cloud basic processing subsystem and a real-time registration subsystem, and adopts a laser three-dimensional positioning method and a GPU acceleration technology to realize real-time positioning comparison of a human body. The method has the advantages that the three-dimensional laser light scanning technology is adopted for scanning a patient, three-dimensional data are obtained, the error can be controlled to be about 0.5 mm, the GPU acceleration and parallel processing technology is adopted for improving the operation efficiency, and the whole operation process can be controlled to be within dozens of seconds.

Description

technical field [0001] The invention relates to the field of radiotherapy, in particular to a method for implementing radiotherapy plan transplantation on a Pinnacle treatment planning system. Background technique [0002] Radiation therapy is one of the indispensable main methods to cure malignant tumors. "Radiation therapy department" or "tumor radiation therapy center" is a fighting group composed of multiple teams, each responsible for their own work and cooperating with each other, so as to be the most effective Protect the normal tissues and vital organs of tumor patients, and completely or maximize the elimination of tumor cells. Radiation therapy for tumors is usually formulated by physicians and physicists after a complete treatment plan, and the therapist spends one month to one and a half months to complete the treatment plan by accurately positioning the patient for irradiation. Each course of treatment takes about For 30 days, 1 to 3 parts were irradiated each ...
