Image processing techniques are widely used in analysing biological images, including images of microarrays and two-dimensional electrophoresis gels from which gene & protein expression levels can be measured. Electron microscopy allows the study of cells and tissues at magnification & resolution well beyond those possible by light microscopy. Scanning electron microscopy is used to investigate the surface structure of biological specimens. Image analysis and handling techniques are necessary for dealing with the large amount of data generated by microscopy techniques.The overview of such techniques will give you the background you need to help design your research project. CT or Computerized Tomography refers to a diagnostic imaging technique which uses X-rays and a computer to view organs & other features inside the body. It is a method of examining body organs by scanning them with X- rays and using a computer to construct a three-dimensional image of that structure. Magnetic Resonance Imaging (MRI) refers to a non-invasive nuclear procedure for imaging tissues of high fat and water content that cannot be seen with other radiological techniques
