Results for median SBRT gamma analysis patient. On the left are the plan (top) and measured green channel film dose (bottom). The green line through the plan dose indicates the location of the line profile that is displayed in the top right section. On the bottom right is the gamma distribution (gamma pass rate: 95.8%). The formula for the absolute % dose difference for a point is 100 × (Di,film − Di,plan)/Dglobal,where Di,plan is the planned dose at point i, Di,film is the film dose at point i and Dglobal is the global reference dose (the max dose within the dose distribution)
