Algorithm and performance of a clinical IMRT beam-angle optimization system [PDF]

, 2003
This paper describes the algorithm and examines the performance of an IMRT beam-angle optimization (BAO) system. In this algorithm successive sets of beam angles are selected from a set of predefined directions using a fast simulated annealing (FSA ...

IMRT in Hypopharyngeal Tumors [PDF]

Strahlentherapie und Onkologie, 2006
Background and Purpose:: Intensity-modulated radiation therapy (IMRT) data on hypopharyngeal cancer (HC) are scant. In this study, the authors report on early results in an own HC patient cohort treated with IMRT. A more favorable outcome as compared to historical data on conventional radiation techniques was expected.
