Abstract

The invention discloses a radiotherapy dose optimization method and device. The method comprises the following steps: acquiring a first reference dose of a target voxel set and an irradiation dose of the target voxel set; optimizing the irradiation dose of the target voxel set according to the first reference dose and a preset target function; wherein the value of the target function is in positive correlation with the difference between the irradiation dose of the target voxel set and the first reference dose; and determining that the irradiation dose of the target voxel set reaches the optimized target dose under the condition that the target function reaches a set condition. The technical problem of low radiation dose optimization efficiency caused by excessive dependence on manual debugging is solved.

Description

technical field [0001] The present application relates to the field of radiotherapy dose optimization, in particular, to a radiotherapy dose optimization method and device. Background technique [0002] The formulation of a tumor radiotherapy plan is a relatively complex iterative process. The plan design mainly goes through the delineation of the target area and organs at risk, the layout of the irradiation field (fixed irradiation field or arc), plan optimization, plan evaluation and final dose calculation. The plan optimization process relies heavily on the experience and skills of the physicist. The physicist needs to continuously try to adjust the optimization constraints and parameters according to the prescription given by the doctor to improve the plan until a satisfactory dose index is achieved. In clinical applications, there is often an actual demand for a corresponding new plan after making some changes to the existing plan or dose, such as the need to continue t...
