Abstract

The invention provides a weight adjustment method and a weight adjustment device of intensity-modulated radiation therapy. The method comprises the following steps of: a, setting a reference dose-volume histogram (DVH) curve to be an optimization target; b, solving a fluence map optimization problem to obtain a current dose-volume histogram; c, comparing the reference DVH curve with the current DVH curve to obtain a DVH evaluation index; d, judging whether to stop weight adjustment, if so, stopping weight adjustment, otherwise, executing a step e; e, adjusting a weight coefficient of an organ, thereby enabling the organ with lower DVH evaluation index to obtain higher weight coefficient, and retuning back to the step b.

Description

technical field [0001] The present invention mainly relates to intensity-modulated radiation therapy in the medical field, and in particular to a weight adjustment method and device for intensity-modulated radiation therapy. Background technique [0002] With the development of radiation physics, radiation biology, clinical oncology and other theories, especially the continuous improvement of medical imaging equipment and computer technology, the radiation therapy (hereinafter referred to as radiation therapy) technology can be continuously improved and developed to better meet the clinical needs. Require. It is a leap forward from the initial common radiotherapy technology to 3Dimensional Conformal Radiation Therapy (3DCRT). Since then, radiotherapy has entered the era of precision radiotherapy, and the incidence of local tumor recurrence and normal tissue complications has been greatly reduced. Intensity-modulated Radiation Therapy (IMRT), developed on the basis of three-...
