Fast non-coplanar beam orientation optimization based on group sparsity

Objective: The selection of beam orientations, which is a key step in radiation treatment planning, is particularly challenging for non-coplanar radiotherapy systems due to the large number of candidate beams. In this paper, we report progress on the group sparsity approach to beam orientation optimization, wherein beam angles are selected by solving a large scale fluence map optimization probl...

Non - Coplanar Magnetic Reconnection

Integral dose investigation of non-coplanar treatment beam geometries in radiotherapy.

PURPOSE Automated planning and delivery of non-coplanar plans such as 4π radiotherapy involving a large number of fields have been developed to take advantage of the newly available automated couch and gantry on C-arm gantry linacs. However, there is an increasing concern regarding the potential changes in the integral dose that needs to be investigated. METHODS A digital torso phantom and 22...

Neighborhood search approaches to non-coplanar beam orientation optimization for total marrow irradiation using IMRT

We consider the beam orientation optimization (BOO) problem for total marrow irradiation (TMI) treatment planning using intensity modulated radiation therapy (IMRT). Currently, IMRT is not widely used in TMI treatment delivery; furthermore, the effect of using non-coplanar beam orientations is not known. We propose and implement several variations of a single neighborhood search algorithm that ...
