Abstract

The adoption of intensity-modulated radiation therapy (IMRT) has resulted in a continuing clinical need for improved tools for commissioning, pretreatment measurements, and in vivo (during treatment) quality assurance (QA) methods. In the early days of IMRT, most medical physicists were restricted to the use of point detectors (Chapter 4) and radiographic film. As patient care continues to demonstrate the benefits of intensity-modulated treatment plans for target coverage and normal tissue sparing (De Neve et al., 2012), we continue to need methods to measure that the intended delivery is achieved. The need for efficient measurement devices (this chapter) and analysis tools (Chapter 14) is balanced with patient safety considerations.
