title: New complete geometrical rapid-test for radiation therapy equipment.
abstract: Daily, weekly and monthly tests of all geometrical performance tolerances for isocentric radiotherapy units can be improved and simplified by a new timesparing comprehensive test procedure. Using a simple auxiliary device, an exact rapid test of isocentre, field-sizes, scales and all optical beam or isocentre indicating instruments is done at the isocentre with only one ready pack film under multiple conditions.
