Reconstruction of Brain MRI Images

The field of medical visualization of organs are needed for accurate diagnosis and treatment of any disease. Brain tumour diagnosis and surgery also requires accurate 3D visualization of the brain. Detection and 3D visualization of the brain and possibly tumours from MRI is a computationally time consuming and error-prone task. The proposed system presents a 3D reconstruction model of the brain which greatly helps the radiologist to effectively diagnose and analyze brain. If the subject is in motion state or there occurs a movement while taking the scan, there might be distortions in the output scan image. In order to avoid such circumstances it is better to reconstruct the 2D image into a 3D space as it is more effective. Thus the quality of the scan image is much better. More than 200 images were used for the training and around 150 images were used for testing. Here the 2D image slices are undergone image pre-processing, image registration, and then reconstruction. For the image registration, the method used is discrete wavelet transform which is more suitable for medical imaging. The proposed system is applicable for the clinical practices.
