Impact of the accuracy of automatic tumour functional volume delineation on radiotherapy treatment planning
2012
Physics in Medicine and Biology
In the past few years several automatic and semi-automatic PET segmentation methods for target volume definition in radiotherapy have been proposed. The objective of this study is to compare different methods in terms of dosimetry. For such comparison, a gold-standard is needed. For this purpose realistic GATE simulated PET images were used. Three lung cases and three H&N cases were designed with various shapes, contrasts and heterogeneities. Four 5 different segmentation approaches were
