In this paper a method based in mesh surfaces approximations for the analysis of 3D anatomical structures in Radiotherapy (RT) is presented. Parotid glands meshes constructed from Megavoltage CT (MVCT) images were studied in terms of the dice similarity coefficient (DICE) and the average symmetric distance (ASD). A comparison with the standard binary images approach was performed. Results suggest that the mesh approach should be adopted to provide accurate comparison between anatomical structures of interest in RT.

Abstract
In this paper a method based in mesh surfaces approximations for the analysis of 3D anatomical structures in Radiotherapy (RT) is presented. Parotid glands meshes constructed from Megavoltage CT (MVCT) images were studied in terms of the dice similarity coefficient (DICE) and the average symmetric distance (ASD). A comparison with the standard binary images approach was performed. Results suggest that the mesh approach should be adopted to provide accurate comparison between anatomical structures of interest in RT.File in questo prodotto:
