Target region partitioning in radiation therapy for minimising irradiation of non-target tissue

摘要

Disclosed is a method for determining an irradiation trajectory for the movement of a treatment device for irradiating an anatomical structure with ionising treatment radiation, the method comprising steps of;acquiring medical image data describing a medical image of the anatomical structure;;determining, based on the medical image data, image concavity data;;acquiring predetermined concavity data;;determining, based on the image concavity data and the predetermined concavity data, partition data;;determining, based on the medical image data, partition boundary data; and;determining, based on the partition boundary data, irradiation trajectory data.
