Digital Processing/Display System for Radioisotope Scanning^1,2,

Fort Howard and Washington

ABSTRACT

A system for automatic transmission, computer processing, and transformation of radioisotope scanning data for final display in contour map form has been developed to evaluate its use and capabilities for biomedical data measurement. It employs an existing scanning, recording and telecomputing configuration to prepare automatically two-dimensional isocount contour maps from computer-processed radioisotope scan data.

The experimental scanning system is comprised of four functional sections: (1) Data collection Station, (2) Transmission System, (3) Computer Processor, and (4) Display Plotter Device. These components and their operation are described and discussed.

The research configuration is utilized to compare and evaluate the effects of (1) count density, (2) count interval time, (3) scanner speed, and (4) definition capabilities in scans performed with phantoms, organs, or on patients presented for clinical diagnosis. By introduction of these data into the automated bioelectronic data collection, telecomputing and display system, improvements in the speed and accuracy of analysis of radioisotope scan data will be demonstrated.

Some capabilities of this system to incorporate a variety of other biomedical data into the present or a modified expanded telecommunication/computer system are briefly presented and discussed.
