  • Reason
    Xio: when the beam template is recalled, xio prematurely initiates a dose calculation, re-snaps the mlc or port to the structure of the current patient , but then fails to re-calculate dose for the new mlc or port position. if no subsequent change is made to force a dose recalculation, xio will display the dose from the original mlc/port shape dose instead of the dose from the re-snapped mlc/port.
