  • Causa
    Under certain conditions photon beams in high energy clinacs may experience a gradual change in beam symmetry potentially reaching an asymmetry of up to approximately 7 % before interlock occurs. at maximum asymmetry this may result in no more than approximately 3.5% dose deviation from expected at any point in the beam. the type of asymmetry normally results in a beam which is higher than desired on one side of the central axis lower on the other side and approximately correct at the central axis. asymmetry value as used here means the peak to peak (over to under) differences observed. therefore a maximum asymmetry of 7% will result in a dose deviation of no more than 3.5% at any point in the beam with a smaller deviation near the central axis of the beam. normally the central axis dose values represent the calibration point and are not affected.
