Impact of Geometric Arrangement of RT Volumes on Dosimetric Planning Goals: Results of a Study for Head and Neck Cancer

The positional relation between the tumor volume and organs at risk (OARs) is an important facet of the radiotherapy planning management. In fact, the geometrical arrangement of the involved structures may affect the treatment plan results. In the present work, the role played by the geometrical setup of the radiotherapy volumes on the quality of a treatment plan is investigated by means of a correlation analysis. The study is based on a...
