Abstract

A brain tumor is an abnormal growth of tissue in the brain. The segmentation of brain tumors, which has been manually achieved from magnetic resonance images (MRI) is a decisive and time-consuming task. Treatment, diagnosis, signs and symptoms of the brain tumors mainly depend on the tumor size, position, and growth pattern. The accuracy and timeliness of detecting a brain tumor are vital factors to achieve the success in diagnosis and treatment of brain tumor. Therefore, segmentation and estimation of volume of brain tumor have been deemed a challenge mission in medical image processing. This paper aims to present a new approach, to improve the segmentation of brain tumors form T2-weighted MRI images using hidden Markov random fields (HMRF) and threshold method. We calculate the volume of the tumor using a new approach based on 2D images measurements and voxel space. The accuracy of segmentation is computed by using the ROC method. In order to validate the proposed approach a comparison is achieved with a manual method using Mango software. This comparison reveals that the noise or impurities in measurement of tumor volume are less in the proposed approach than in Mango software
