EPID-based MLC Hancock Test

Description

The Hancock tests are designed to use the Elekta iView imager to produce a series of images to automatically measure leaf position against a measured isocenter position. For MLC’s with backup jaws the test also measures the jaw position in relation to isocenter and the jaw leaf setback measurement..

The analysis in this routine corresponds to the recommendations of AAPM Task Group TG142.
