Automatic planning for radiation dosimetry

摘要

This invention relates to the automatic determination of beam parameters and other criteria to determine a dose plan of radiation on a target volume. The method involves determination of geometric and other radiation involvement criteria, with search of a phase space on the incoming direction of the irradiation beam ports. The evaluation of the goodness of fit, based on parameter thresholds and other considerations, makes it possible to search on the entire phase space of possible beam directions towards the target volume so as to improve the treatment planning dosimetry. The invention applies to circular or non-circular collimator shapes, and can be illustrated by use with a linear accelerator (LINAC) as a means for X-ray delivery to a target volume such as a tumor within a patient's body.
