Harmonization of dose prescription for lung stereotactic radiotherapy.

Background And Purpose: Pulmonary stereotactic treatments can be performed using dedicated linear accelerators as well as robotic-assisted units, and different strategies can be used for dose prescription. This study aimed to compare the doses received by the tumor with a gross tumor volume (GTV)-based prescription on D using a robotic-assisted unit () and planning target volume (PTV)-based prescription on D using a dedicated linac ().

Material & Methods: Plans of 32 patients were collected for , and a dose of 3 × 18 Gy was prescribed using type A algorithm and recalculated using a Monte-Carlo (MC) algorithm.
