The critical importance of comprehensive treatment verification to patient safety is a topic of major current interest. The increase in complexity of modern treatments has created a direct need for correspondingly more sophisticated and comprehensive verification tools. A variety of new dosimetry techniques, QA devices, and verification rationale have recently emerged with potential to transform the process of both commissioning and routine patient treatment verification. A common goal of many of these systems is a more comprehensive measurement of the delivered dose in 3‐dimensions (3D) with high accuracy and spatial resolution. Several of these 3D or semi‐3D systems can also measure delivered dose in moving phantoms, and can therefore address important verification questions in 4D. Other approaches are capable of estimating the in‐vivo dose delivered to patients by back‐projecting measured exit fluence acquired during treatment. This symposium aims to review both the clinical rationale and clinical implementation of these important developments in complex treatment verification. Speakers will address the following topics in the context of clinical verification of advanced treatments like IMRT, VMAT/RapidArc, tomotherapy, and SRS/SBRT etc): 1) EPID dosimetry — both in‐vivo and ex‐vivo, 2) dosimetry with diode and chamber arrays, 3) 3D dosimetry with radiochromic plastics and gels, 4) computational algorithms for independent verification. The characteristics, state‐of‐the‐art, limitations, and clinical experience from these techniques will be reviewed. Learning objectives: 1. gain insight into the dosimetric challenges posed by advanced radiation treatment techniques 2. appreciate the importance of comprehensive treatment verification to patient safety 3. understand the rationale and capabilities of dosimetry techniques for comprehensive treatment verification, both in‐vivo and ex‐vivo. © 2011, American Association of Physicists in Medicine.
