WebIn our case, the 15mm Brainlab stereotactic cone is used as the radiation pattern for calibration of EBT3 gafchromic film. The 15mm cone was chosen because its output factor is easier to measure using stereotactic detectors than that of smaller cones. Five 15mm cone irradiations of different MUs (40, 80, 120, 160, and 200) on a strip of film ... WebThe 15mm cone was chosen because its output factor is easier to measure using stereotactic detectors than that of smaller cones. Five 15mm cone irradiations of different MUs (40, 80, 120, 160, and 200) on a strip of fi lm are used to generate the dose profi le for the selected stereotactic cone.
