(U.K.)Īn optical device for placing automatically a plurality of images at selected locations on one film comprises a stepping motor coupled to a rotating mirror and lens. The cells are addressed and divided in a pseudo-random pattern so that, to the observer, the whole image appears to fade smoothly and evenly. The digital inability to store each single event as a dot which fades exponentially with time has been solved by adding each event into the appropriate cell of a digital display matrix, and then periodically dividing the contents of each image cell by two. It incorporates an automatic brightness control which ensures that the image does not saturate at high count density, and the saturation can be changed manually allowing areas of low counts to be examined in the presence of high counts. The performance is superior to the analogue oscilloscope in that the image is displayed with 16 shades of grey.
It uses digital and video techniques to produce an image quality suitable for use in positioning patients under the camera at a low cost (total cost of materials used, Pound500). The system briefly described is intended as a direct replacement for the analogue persistence oscilloscope, particularly in systems without a computer processor.
