Abstract: A method of processing a radiographic image obtained with a slot-scanning radiographic system to compensate for scattering of the illuminating beam in the tissue being imaged. A conventional circularly symmetric scatter mask, for example a point spread function, is adjusted to take account of the shape of the detector and time delay integration used in the slot scanning system, the presence of an air gap between the detector and the bottom of the tissue being imaged, and the collimation of the radiation beam. The result is a sharpened and shortened point spread function.

Abstract: Comparing first and second images taken on different imaging systems and under different exposure conditions is achieved by the steps of: applying a model to the data representing the first image, which model simulates at least one process step in the creation of said first image, to derive a representation of the first image at a level of processing common to the creation of the second image; and applying a further model to said representation, which model simulates at least one process step in the creation of said second image, to derive a further representation of the first image which corresponds to the same level of processing as said second image.

Abstract: A method of communicating medical information comprising the steps of: obtaining raw image data from at least a portion of the body of a subject; constructing a computer representation of the raw image data; applying image processing to the computer representation; and giving the result of the image processing to a person to whom medical information contained in the image data is to be communicated.
