CHAPTER 1



INTRODUCTION



1.1 BACKGROUND



Research related to medical imaging has produced several techniques for diagnosis purpose like CT, MRI and ultrasound. Each one has its own advantages and disadvantages. Medical imaging is the procedure of creating visual representations of the interior body for medical diagnosis. It helps in revealing internal structures which are hidden inside skin and bones, as well as to treat diseases and for diagnosis purpose. It identifies abnormality through database of physiology and normal anatomy .Imaging of organs and tissues are removed that can be performed for medical reasons. This procedure is a part of pathology and not of medical imaging.

The important properties of a good image denoising model are the one in which the noise is completely removed while preserving edges. One of the common approaches is to use a Gaussian filter or solving the heat–equation with the noisy image as input–data such as a linear, 2nd order PDE–model. Image denoising is important issue which is found in diverse image processing like digital images, SAR images medical imaging, etc and computer vision problems.



1.2 USES



US imaging is medical tool that can help a medical conditions, physician evaluate, and diagnose treat. US imaging procedures include:
