  • Causa
    When vmat control points are distributed with a wider gantry angle spacing than 4 degrees, the dose calculation will not be accurate. such plans will never be generated by raystation and imported plans with this wide gantry angle spacing will normally not be possible to use for dose calculation in raystation. however, if the imported plan is assigned to a vmat enabled machine model with minimum dose rate = 0.00 mu/min and minimum gantry speed = 0.0 degrees/s, it is possible to calculate dose., , depending on the individual plan, local dose inaccuracy in some regions close to the patient surface may range from under a percent to several percent of dose max. the deviation increases with the gantry angle spacing and with the number of affected control points. the problem will mainly occur in the region furthest away from the isocenter.
