Purpose/Objective:

Accurate radiotherapy treatment requires careful quality assurance (QA) of the treatment units used. Currently, the built-in Machine Performance Check (MPC) for Halcyon is used to determine the isocenter accuracy at Helsinki University Central Hospital (HUCH). Mechanical measurements with an accelerometer are used to test the gantry angle.
