A dosimetric analysis of a spine SBRT specific treatment planning system.

A dosimetric analysis of a spine SBRT specific treatment planning system. J Appl Clin Med Phys. 2018 Nov 20;: Authors: Saenz DL, Crownover R, Stathakis S, Papanikolaou N Abstract PURPOSE: The Brainlab Elements treatment planning system utilizes distinct modules for treatment planning specific to stereotactic treatment sites including single or multiple brain lesions as well as spine. This work investigates the hypothesis that an optimization tailored specifically to spine can in fact create dosimetrically superior plans to those created in more general use treatment planning systems (TPS). METHODS: Ten spine patients at our institution were replanned in Brainlab Elements, Phillips Pinnacle3 , and Elekta Monaco. The planning target volume (PTV) included the vertebral body (in either the thoracic or lumbar spine), pedicles, and transverse processes. In all plans, the target was prescribed 20 Gy to 95% of the PTV. Objectives for the study included D5%
