Chondroblastoma is a type of benign bone tumor originates from chondroblasts. The rate of misdiagnose is much higher among benign bone tumors. The treatment method is different in both cases. Computer Aided Diagnosis (CAD) system helps more for reducing the rate of misdiagnosis. Segmentation is used for the selection of area of interest from medical images. The possible ways of diagnosis is X-Ray, CT, MRI and Biopsy. Active contour modeling is tested using region based approach. Various levels set and Gaussian distribution function is used for segmentation process. The proposed system separates similar intensity values of mean and different intensity values of variance. This system segments similar intensity regions as suspected area. At the end of this work, the system can extract the exact position and shape of the chondroblastoma affected region in bone.
