An intensity map x is a m × n matrix with nonnegative integral entries corresponding to beamlets. We will assume for this work that thd MLC has m rows caled channels, and n columms. One "step" in a sequaence can then be coded as a m × n 0-1(read"zero "one) shape matrix with entries corresponding to the entries in the intensity map. A O in the shape matrix codes that a leaf from the MLC blocks the region corresponding to the entry, and a 1 marks this region open for this step.
