Abstract
By using a marker excellent in durability in a multi-leaf collimator, positions of the markers are accurately detected, and positions of the leaves are accurately controlled. The markers are plates containing a phosphor, and surfaces of the plates are fixed to surfaces of the leaves such that end surfaces of the plates are located on predetermined end surfaces of the leaves. An image of the end surfaces of the plates is captured by a camera, and positions of the end surfaces are recognized by image processing.
