Abstract

In this paper, we have tried to encapsulate the recent developments in the field of Symmetry based approaches to detect tumor and then came up with a new parameter which plays a crucial role in proving that a high degree of Symmetry is present in an axial normal human brain MRI (Magnetic resonance Imaging) and this symmetry get affected or not present in abnormal cases highlighting the fact that tumor might be present. This paper also reveals one of the major technical flaw or loophole that is present in almost all Symmetry based approaches to detect tumor. As Symmetry is one of the most important properties of a human brain that can be utilized to detect the presence of tumor and other anomalies present in the human Brain. This paper tried to provide the proof of symmetry in human brain through a pixel based analysis using a number of neuro images cases. For the pixel based analysis T2 weighted MRI modality images are used. In this paper we are using T2 MRI images because in it an anomaly appears Hyper intense (brighter than the normal brain tissue).
