Optimizing TrueBeam jaw calibrations to reduce positional errors at customizable gantry and collimator angles

Background

Clinical medical physicists in a radiotherapy setting are aware of the importance of maintaining linac collimators with high positional accuracy, especially when used to form junctions; however, there is a lack of quality control options available. This is especially true when trying to improve jaw matching in junctions or when trying to maintain accurate jaws across gantry angles other than 0 degrees.
