Formally, an intensity profile is represented as a nonnegative integer matrix an aperture is represented as a binary matrix whose ones appear consecutively in each row. In this paper, we investigate this last problem. To deliver these intensity profiles to the patient, a third phase must decompose them into a collection of apertures and corresponding intensities. This intensity profile is selected to ensure that certain targets receive a required amount of dose while functional organs are spared. The first phase determines a set of beam angles through which radiation is delivered, followed by a second phase that determines an optimal radiation intensity profile (or fluence map). IMRT treatment planning is usually performed in three phases. We consider a problem dealing with the efficient delivery of intensity modulated radiation therapy (IMRT) to individual patients.
