摘要： A collimator for a radiotherapy apparatus, comprising a block of isolation-attenuating material having a front face forming the leading edge of tie block and at least one main rear face defining the trailing edge of the block, in which the or each rear face is substantially planar in the direction of the depth of the block and non-parallel to the front face. The collimator may form part of a radiotherapy apparatus, and methods of operation of such apparatus are described.
