SU‐E‐T‐535: Linac Based Multiple SRS Targets Plan Evaluation: Understanding Conformity Index Generated Form BrainLab IPlan RT Dose 4.1 SRS Planning System
Abstract:Purpose:
The study intent is to provide a practical method of extracting Conformity Index for multiple Stereotactic Radiosurgery (SRS) target plans generated from BrainLab iPlan RT Dose 4.1 planning system (CIiPlan).
Methods:
CIiPlan is the ratio between normal tissue volume (VN, IDL) and target volume (VPTV, IDL) encompassed by the prescription isodose line (IDL). BrainLab iPlan RT Dose 4.1 planning and physics documents lack details on how to retrieve and interpret CIiPlan parameters of multiple SRS targets.… Show more
