Dose calculator minimizes QA bottleneck

In proton therapy centres, treatment plans are commonly checked before the start of treatment by delivering them to a phantom on the treatment couch. However, such dose measurements are labour intensive, time consuming and unfeasible for use as part of a daily adaptive treatment regime. In a move towards eliminating patient-specific measurements, researchers at the Paul Scherrer Institute in Switzerland have developed an independent-dose-calculation (IDC) system for quality assurance of pencil-beam plans, as well as commissioning of treatment-planning and delivery systems.
