A tumor is caused by abnormal growth of cells, which looks like an expansion. For more than ten years, the algorithm of pulse coupled neural network (PCNN) has been successfully applied to image interpretation, including image segmentation [6]. The use of PCNN is a modification of eckhorn's cortical neuron model. Pulse coupled neural network can smooth image, segment image and extract feature. Current technologies involve noninvasive imaging detection, diagnosis, and evaluation of many common and less common diseases. One of the imaging techniques is magnetic resonance imaging (MRI). Through this procedure, physicians obtain images, or 'slices', of various parts of the human body. Then, they analyzed the slices and collected information to perform various tasks, especially brain extraction [2]. One area of particular interest is the human brain. MRI allows researchers and doctors to study the functional and physical properties of the brain with less risk for patients.
