摘要：
A contour collimator for radiation therapy has a plurality of diaphragm elements that are movable with respect to each other by means of drive units. The diaphragm elements of the invention are supported only on the side near the drive units for ease of movement. This allows larger contour collimators to be constructed having relatively heavy diaphragm elements while retaining relatively small motors.
