Image Processing
Image processing is any form of signal processing for which the input is an image (in our case a nuclear medicine image); the output of image processing may be either another image or a set of parameters related to the original image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.
An image artifact is any feature which appears in an image which is not present in the original imaged object. An image artifact is sometimes the result of improper operation of the imager, and other times a consequence of natural processes or properties of the human body. It is important to be familiar with the appearance of artifacts because artifacts can obscure, and be mistaken for, pathology. Therefore, image artifacts can result in false negatives and false positives.
