Abstract

A major challenge for image guided tumor ablation is the high treatment variability due to heterogeneous tissue characteristics and thermal sinks. In this work, we present a methodology to analyze the geometry of the treatment zones and treatment zone variability. Our first contribution is an applicator centric co-ordinate system which enables us to compare treatment zones and vendor specifications across patients. Our second contribution is the analysis of the shape of the ablation zone using applicator centric longitudinal 2D cross sections. We present initial results of applying this methodology to analyze the geometry and variability in synthetic examples like ellipsoid, sphere and real microwave ablation zones in lung and liver.
