Anthropomorphic radiological phantoms for mammography.
Anthropomorphic radiological phantoms are useful in evaluating image quality in mammography by providing realistic detection tasks to the observer. Methods for creating such phantoms, based on original patient mammograms, are described. Photochemical enhancement techniques and application of fractal interpolation methods for improving the fine detail information contained in such phantoms are discussed. Approaches to incorporating additional calibrated test targets within the phantom are also described.
