Radiotherapy is an effective treatment of solid cancers but it is challenging to treat bulky tumors with radiation. One of the major difficulties is to adequately spare normal tissues surrounding the lesion. Spatial fractionation radiotherapy has been proven to be effective in reducing radiation induced toxicities while providing excellent tumor control. From the GRID therapy of the early 20th century to the most recent innovative radiation modalities using spatial fractionation concept, this educational symposium aims to provide an overview of clinical implementation of spatial fractionate radiation techniques with unique physical properties that could be exploited to improve therapeutic index for cancers.
Learning Objectives:
1. To identify the physics and dosimetry challenge of SFRT
2. To outline the clinical implementations of SFRT techniques including physical and MLC grid, lattice technique and proton-based techniques
3. To describe the dosimetry and QA of SFRT fields, and to identify important physical and dosimetry parameters to report for SFRT treatment
