Abstract
A method and a dose planning module for planning a treatment session of a patient by means of a radiation therapy system includes a radiation therapy unit having a fixed radiation focus point. The method includes obtaining a target volume of a region of a patient to be treated during a treatment of a patient in a radiation therapy unit, the target volume being modeled as a three-dimensional voxel representation; selecting an isodose level for the planned treatment; determining shots to be delivered during the treatment, each shot being modeled by a spatial dose volume distribution of radiation represented by a three-dimensional voxel representation, the shape of the spatial distribution depending on the specific collimator setting and the selected isodose level; and selecting shots in a decreasing volume order for the dose planning.
