Abstract
The invention relates to a leaf module (102) for a multi leaf collimator (132) comprising a leaf unit (104) and a leaf drive unit (106) wherein the leaf unit (104) comprises a leaf (108) for shielding beams from a selected area and the leaf unit (104) is mounted displaceably in an adjusting direction (110) wherein the leaf drive unit (106) is designed to displace the leaf unit (104) linearly in the adjusting direction (110) and wherein the leaf drive unit (106) comprises at least one drive mechanism (112) being designed in such a way that the drive mechanism (112) operates based on pneumatic actuation. Furthermore the invention relates to a multi leaf collimator (132) comprising a plurality of leaf modules (102) according to the invention. The invention is based on the objective of designing a leaf module (102) and a multi leaf collimator (132) as compactly as possible while achieving a simple reliable and variable adjustability of the leaf unit (104). The invention is regarded to be particularly suitable for implementation in Cobalt 60 or mid to low end linac radiotherapy apparatuses.
