摘要：
A system and method for controlling radiation delivery from a radiation source (20) to an object are disclosed. The method includes defining a field on the object for radiation delivery. The field includes a plurality of cells (102), each cell having a defined treatment intensity level. The cells are grouped to form a matrix (100) having at least one dimension approximately equal to a width of a collimator leaf (97, 98) capable of blocking radiation emitted from the radiation source. The method further includes decomposing the matrix into orthogonal matrices and optimizing delivery of the radiation by selecting a combination of orthogonal matrices to minimize junction effects.
