Overview of PDT treatment planning framework for a female patient with a metastatic T8 sclerotic lesion: (a) extraction of contours from stereotactic body radiation therapy plan using the Dicompyler tool, including the clinical target volume or metastasis (green) and spinal cord (blue), (b) segmentation of the original CT dataset using ITK-SNAP to delineate the metastasis (purple), normal bone (green), spinal cord (red), and muscle (yellow) at the T8 level, (c) generation of the 3D mesh geometry using MeshTool for light dose simulation with FullMonte Methods.
