Abstract

Three-dimensional reconstruction is the process of acquiring the volumetric information from two dimensions, converting and representing it in three dimensions. The reconstructed images play a vital role in the disease diagnosis, treatment and surgery. Brain surgery is one of the main treatment options following the diagnosis of brain damage. The risk associated with brain surgery is high. Reconstructed brain images help the surgeons to visualize the exact location of tumor, plan and perform the surgical procedures from craniotomy to tumor resection with high precision. This survey provides an overview of the three-dimensional reconstruction techniques in MRI brain and brain tumors. The triangle generation methods and support vector machine methods are briefly described. The advantages and disadvantages of each method is discussed. The comparison reveals that Immune Sphere Shaped Support Vector Machine is the best choice when execution time is considered and triangle mesh generation algorithm is the best when visual quality is considered.

Introduction

The brain is an intricate organ in the human body. The brain is constantly active and controls all the other organs in the body. Human brain is composed of soft tissues which are very irregular, and the reconstruction of such tissues is a complicated task. Brain tumors are abnormal and uncontrolled proliferations of cells in brain. Apart from brain tumor, these are some disorders like stroke, cerebral palsy, Parkinson’s disease, traumatic brain injury, Alzheimer’s disease, Batten’s disease that lead to intense brain damage. The physicians and surgeons use computer aided diagnosis system to improve the accuracy of diagnosis. Three-dimensional reconstructed brain aids in viewing the pathology of brain related diseases. Brain surgery is one of the main treatment options following the diagnosis of brain damage. The risk associated with brain surgery is high and is very difficult to make an accurate prognosis (Bhujbal, de Vos, & Niclou, 2014). A detailed and well planned surgery can reduce the potential risk associated with brain surgery. Imaging technology plays an important role in the diagnosis of disease. High reliability images are produced by medical imaging which offers the potential for advances in medical field. Magnetic Resonance Imaging (MRI) is the long-established imaging technique to acquire the images of soft tissue in brain. The MRI images provides information in two dimensions which needs to be converted to three dimensional images or models that provides better visual effects. Reconstruction is the process through which these images can be obtained. The three-dimensional reconstructed images help the surgeons in examining the surface and anatomical structures of the brain. The patient specific reconstructed images improve the confidence of neurosurgeons while handling complex cases (Lamata et al., 2010). The requisite of powerful visual aids that assist in pre-procedure planning for reducing the risk in brain surgery is the motivation of the survey.
