Abstract
A prototype inexpensive analog optical pseudocolor encoder utilizing white-light processing has been developed for applications in diagnostic imaging. The system is capable of handling a large amount of information and has a high signal-to-noise ratio. It may be useful as a relatively economical means for transforming gray-scale images into color coded images. Pseudocoloring may be beneficial in achieving better diagnostic accuracy over gray-scale display because it has been shown to be able to increase the sensitivity of the observer to the display and it allows multiparameter presentation. In this paper, a theoretical treatment of the technique and preliminary results obtained for a conventional X-ray radiograph will be given.
