摘要:
In a contour collimator for radiation therapy, a variable aperture is formed by two stacks of aperture plates, which are mounted opposite one another. The aperture plates are connected to a setting mechanism in order to alter the aperture created between the opposed aperture plates. All the aperture plates of each stack are arranged on a respective axle. The aperture plates can be rotated individually around the axles and into the aperture.
