Dosimetric and Delivery Assessment of Stereotactic Body Radiotherapy Using Flattened and Unflattened Beams for the Single-Isocenter Treatment of Multiple Liver Targets

Key Points

This research aims to assess the dosimetric performance and treatment delivery of stereotactic body radiotherapy with different beam types.
Compared dosimetric data between flattened and unflattened beams for liver targets.
Evaluated beam-on time for treatment sessions with different beam types.
Implemented breath-hold techniques to measure efficiency.
Flattening filter-free beams reduced beam-on time significantly in certain scenarios.
Higher dose rates with 10FFF did not lead to decreased overall treatment time.

Abstract

Flattening filter-free (FFF) beams reduce beam-on time (BOT), providing an advantage for breath-hold techniques. However, despite the higher dose rate of 10FFF, no additional reduction in overall treatment time was observed.
