System and method for generating isocenter laser parameter in radiotherapy

Abstract

The invention discloses a system and a method for generating an isocenter laser parameter in radiotherapy. An image collecting device is used for scanning and obtaining a layer-by-layer scanned image file; a therapy plan is designed by a radiotherapy planning system according to the image file and a therapy plan file is generated, wherein the therapy plan file comprises N irradiation fields arranged according to the therapy requirement and isocenter coordinates of all the irradiation fields; the image file and the therapy plan file outputted by the radiotherapy planning system are read by an isocenter laser parameter system; and the isocenter laser parameter is used for performing coordinate conversion and calculation on the read parameter, obtaining the isocenter laser parameter capable of being received by a laser positioning system and sending to the laser positioning system. The direct communication between the radiotherapy planning system and the laser positioning system is realized, the interconnection between devices is realized, the clinical requirement of the radiotherapy is met and the therapeutic efficiency is increased.

Description

technical field [0001] The invention relates to a system and a method for generating laser parameters of the middle center of radiotherapy. Background technique [0002] The radiation therapy planning system is a high-precision radiation therapy. The patient's CT image file materials required for radiation therapy planning are obtained through CT scanning, so as to accurately outline the treatment target area. The radiation therapy planning system is designed according to the CT image files. Radiation therapy plan. The radiation therapy planning system sets N irradiation fields and corresponding N isocenters according to the treatment needs. After the radiation therapy plan is designed, the laser positioning system marks the isocenter of the patient according to the radiation therapy plan. At present, most radiotherapy planning systems cannot directly generate the isocenter laser parameters required by the laser positioning system, and need to manually move the treatment bed...

AI Technical Summary

Problems solved by technology

At present, most radiotherapy planning systems cannot directly generate the isocenter laser parameters required by the laser positioning system, and need to manually move the treatment bed for positioning, and only the isocenter-related information files output by the radiotherapy planning system need to be explained and analyzed. In order to generate the isocenter laser parameters required by the laser positioning system

The existing methods have the following defects: 1. Most treatment plans cannot directly output isocenter parameter files that can be read by a specific laser positioning system; 2. The laser system cannot be directly used for direct positioning, which reduces treatment efficiency
