Abstract

The present application provides a method, device and computer system for determining beamlet intensity in a radiotherapy system. The method according to the present application is based on the compressive sensing theory by introducing the position of the radiation field and the sub-beam into the traditional objective function to obtain the objective function. Then the objective function is optimized to select a backup field from multiple fields. Based on the spare fields, the sub-beam intensity is obtained by optimizing the traditional intensity-modulated radiotherapy plan.

Description

technical field [0001] The present application generally relates to methods and apparatus and computer systems for determining beamlet intensities in radiotherapy systems. Background technique [0002] Radiation therapy is one of the main techniques for treating malignant tumors. Its purpose is to irradiate the tumor (tissue or target area to be irradiated) as much as possible, and to minimize the dose to the surrounding normal tissues. IMRT (intensity modulated radiation therapy, intensity-modulated radiation therapy) developed from three-dimensional conformal radiation therapy is a kind of radiation therapy. IMRT requires that the intensity of sub-beams (also called beamlets) in the radiation field be adjusted according to certain requirements. It adjusts the sub-beam intensity according to the three-dimensional shape of the target area and the specific anatomical relationship between the vital organs and the target area under the condition that the shape of each radiatio...
