Abstract
A multi-leaf collimator can comprise two banks of leaves facing each other across the radiation field, and an actuation member or actuation means configured to control the location of each leaf, for example, to control the degree to which each leaf is extended into the radiation field. The leaves of the multi-leaf collimator can comprise at least one radioluminescent marker that can emit illumination light, which can be used to accurately determine the position of the leaves.
