Basic Principles of Image Generation for Ultrasound, X-Rays, Magnetic Resonance, Computed Tomography and Positron Emission Tomography
The usual aim in generating any kind of image in a body organ is to decide whether or not an abnormality is present and/or to follow the temporal variations of the abnormality during the course of a therapeutic treatment. Therefore, the two main goals of a human expert observer are: to detect the abnormality and to recognize it as such. Logically, the detection must occur prior to any useful recognition, however both procedures can be aided by improving the quality of the image by means of any post-processing techniques.
