WebJun 15, 2014 · Purpose To implement and evaluate an image-based Winston-Lutz (WL) test to measure the displacement between ExacTrac imaging origin and radiation isocenter on a Novalis Tx system using RIT V6.2 software analysis tools. Displacement between imaging and radiation isocenters was tracked over time. WebResults: A good agreement between our method and the film‐based method was achieved. Particularly an average discrepancy of 0.06 mm was obtained compared to the results of the RIT 113. Conclusions: An EPID‐based Winston‐Lutz test has been developed by applying a circular Hough transform.
