Abstract
|
|
|
|
Multileaf Collimator is an essential tool for conformal therapy. We have measured the scallop penumbars of a poligon-shape field produced by Multileaf Collimator(MLC) with various leaf widths and the penumbra from conventional block, and compared the difference between them for the energy of photons, leaf widths, and angle of filed edges in order to find out the optimum leaf width. In addition, we have simulated a treatment of 20 factionations with errors of patient positioning. Optimum cost-benefit balanced leaf width is 8 mm.
