Abstract:PET-guided radiation therapy treatment planning, clinical diagnosis, assessment of tumor growth and therapy response are dependent on the accurate delineation of the tumor volume. Several PET segmentation techniques have been proposed in the recent years. Most these techniques fail in the presence of heterogeneity in the lesion. In this work, an active contour model based on the work presented by Chan and Vese (2001) is proposed to handle the heterogeneity of the lesion uptake. In the proposed method, the fitt… Show more
We proposed and demonstrated an automatic framework for significantly improved segmentation and labeling of homogeneous vs. heterogeneous tumors in lung [F]FDG-PET images.
