A Global Score-Driven Beam Angle Optimization in IMRT

Abstract: Abstract. Radiation therapy is one of the main treatment modalities for cancer. The objective of radiation therapy is to eliminate all cancer cells by delivering a prescribed dose of radiation to the tumor volume while sparing at the same time the surrounding tissues. Intensitymodulated radiation therapy (IMRT) is a sophisticated technologicallydriven type of radiation therapy where non-uniform radiation fields are used to irradiate the patient from different beam angle directions. Appropriate selection of bea… Show more

“…In this paper, a new score based on clinical dosimetric values weighted by its clinical importance, as described by Ventura et al (2016), is introduced and embedded in a parallel multistart derivativefree optimization framework that explores thoroughly the BAO problem continuous search space. Preliminary tests using this score to guide a simpler BAO search lead to promising results for a singlepatient case (Rocha et al, 2017). Unlike previous scores proposed for BAO, this score is obtained after solving the FMO problem and thus BAO and FMO are considered simultaneously.…”
