A circular matrix-merging algorithm with application in Volumetric Intensity-Modulated Arc Therapy
2015
Theoretical Computer Science
Preserved Fulltext
This problem arises in Volumetric Intensity-Modulated Arc Therapy (VMAT) for radiation cancer treatment, where the circular structure represents a delivery arc path of 360 • around the patient and the ...
In this paper, we study an optimization problem, called the circular matrix-merging (CMM) problem: Given a cyclic sequence of n non-negative matrices that are associated with some locations on a circle ...
