A complete system for recording, processing and displaying radioisotope scan data has been developed. Digital electronic techniques are used throughout the system in order to make maximum use of the available information and provide precise control over display parameters. Data are recorded on seven-channel punched paper tape at a minimum sampling interval of 2 mm. At the same time, two forms of output are produced: a typewritten digital matrix and a specially developed form of high-capacity linear dot-density display. The display, produced on a c.r.t. and recorded on Polaroid film, incorporates a unique method of ''character'' generation which increases the effective dynamic range of the film while masking the elemental structure of the image and avoiding the production of random spatial noise. Several versions can be produced on hard copy within a minute of the completion of the clinical procedure. This approach to radioisotope scanning has greatly assisted in the implementation and interpretation of routine clinical studies.
