Small Field Dosimetry Comparing Measured Data Versus the ADAC Pinnacle 3 Model

Abstract

Intensity Modulated Radiation Therapy (IMRT) is rapidly becoming the standard of care for external radiation beam therapy. With IMRT, the radiation beam is effectively broken up into thousands of tiny pencil-thin radiation beams. High speed computers employing complex dose algorithms have the ability to plan and predict doses for IMRT treatment plans. While this method can optimize conformity to tumors and provide better sparing of surrounding tissue, it also presents a host of challenges due to reliance on dosimetry data for small field sizes. Small field dosimetry in itself is a challenge. There many factors that can influence the accuracy of the data. Despite these obstacles it is imperative that accurate data be used in treatment
