Physical Characteristics of Fixed and Dynamics Collimator for Cyberknife M6


This research describes the estimation and quantization of physical benefit for the fixed/variable aperture collimator (Iris) of Cyberknife M6. The fixed collimator and Iris were measured of output factors in different depths (650, 800 and 1000 mm) with an ionization chamber inside a water phantom, and the physical characteristic of profile was compared in… (More)
