The application of magnetic image memorizers has created new possibilities for the presentation of roentgenological images. The TV signals from various x-ray images of the same object, e.g., different phases of its movement, are, by suitable subtraction and/or addition, combined into one picture or a sequence of combined pictures. The information required for establishing the diagnosis can be more easily and clearly recognized than on the original roentgenograms. This is particularly the case when the combined image is displayed on a color television monitor. It is then possible to present the different phases of movements of the object in different colors: time differences become color differences. This has been found to be of particular interest in the study of cerebral blood-flow patterns.
