Dosimetric verification of accuracy of field junctions of a MLC head. White and black levelled regions represent dose inhomogeneities below 10%. Left: One double half collimated quadrant beam (45°) was irradiated 4 times with relative intersegmental collimator rotations of 0°(I), +90°(II), +180°(III), -90°(IV). Right: 4 segments, each irradiated in different quadrants (I-IV) by changing the field aperture with a fixed collimator rotation (45°).
