110321 Basic Image Processing System for CAT Scans Version: May 1977 Submitted by: M. W. Vannier, University of Kentucky Medical Center, Lexington, KY Operating System: RT-11 Source Language: FORTRAN/RT-11 Memory Required: 16K Hardware Required: Disk recommended, Magtape unit Keywords: Medical Applications Abstract: A complete Image Processing Software System written in FORTRAN/RT-11 for processing CAT scan images is available. The system contains programs for decoding magtapes in any arbitrary format and transferring selected contents to disk. Subsequent line-by-line processing of the CAT scan images will produce averages, laplacians, gradients, median smoothing and hyperbolic gray level reassignments for CAT scan images. An application of the system to images from an Ohio Nuclear Delta Scan is described. Media (Service Charge Code): Write-Up (AA), Source Listing (BB), 600' Magnetic Tape (MA) Format: RT-11
