Title: | A Minimum Cost Flow Formulation for Approximated MLC Segmentation | Contributor(s): | Kalinowski, Thomas (author) | Publication Date: | 2011-03 | Early Online Version: | 2011-02-11 | DOI: | 10.1002/net.20394 | Handle Link: | https://hdl.handle.net/1959.11/26778 | Abstract: | Shape matrix decomposition is a sub-problem in radiation therapy planning. A given fluence matrix has to be written as a sum of shape matrices corresponding to homogeneous fields that can be shaped by a multileaf collimator. We solve the problem of finding an approximation of satisfying prescribed upper and lower bounds for each entry. The approximation is determined such that the corresponding fluence can be realized with a prescribed delivery time using a multileaf collimator with an interleaf collision constraint, and under this condition the distance between and is minimized. | Publication Type: | Journal Article | Source of Publication: | Networks, 57(2), p. 135-140 | Publisher: | John Wiley & Sons, Inc | Place of Publication: | United States of America | ISSN: | 1097-0037 0028-3045 |
