From 3rd symposium on sharing of computer programs and technology in nuclear medicine; Miami, Florida, USA (16 Jun 1973). In proceedings of third symposium on sharing of computer programs and technology in nuclear medicine. The production of multiple luminance levels on a general purpose oscilloscope using a technique of variable dot redisplay frequencies is convenient for photographic recording of computer produced images. The display described permits the use of any number of gray staps desired and permits the contrast between steps to be rapidly changed according to the wishes of the operator or according to program instruction. Distorted gray scales are used in an attempt to enhance the perception of minor variations that may occur in a brain image due to a lesion in the cerebral hemispheres. (auth)
