Three Dimensional MR Brain Image Reconstruction and Interactive Segmentation Based Tumor Region Extraction Using Active Contour Models

Magnetic resonance imaging (MRI) system projects the anatomical structures of brain onto spatial domain. Three-dimensional (3D) construction of brain tumor using several slides of MRI has always been of keen interest for diagnosis and for research purpose. This paper presents a three dimensional brain image reconstruction methodology which is very much helpful in predicting the depth of any abnormality in the image and also proposes an active contour based approach for the extraction of the abnormal (tumor) region. The extracted regions are modeled using Iso surface 3D view models.
