摘要：A system and method of the present invention for controlling radiation deliveryfrom a radiation source to an object are disclosed. The method generally includes
defining a field on the object for radiation delivery. The field includes a plurality of cells,each having a defined treatment intensity level. The cells are grouped to form a matrixhaving at least one dimension approximately equal to a width of a collimator leaf capableof blocking radiation emitted from the radiation source. The method further includesdecomposing the matrix into orthogonal matrices and optimizing delivery of the
radiation by selecting a combination of orthogonal matrices to minimize junction effects.
