Abstract

The angiographic workstation (AWOS) is an extended analysis system for digital quantitative coronary angiography. It is based on the SMI 5 image processor architecture with a fast MULTIMUX bus. A 32 Bit SUN SPARC II computer with a 760 MBytes winchester system disk, a 2 GBytes fast image disk and a 128 MBytes scene memory is connected via high speed link (HSL) to HICOR IS and via ETHERNET to POLYTRON 1000 imaging system. AWOS offers the possibility to display and to process digital angiograms from digital imaging systems, and 35 mm cine images digitized by a frame-grabber from an ARRIPRO-35 cineprojector. All standard calibration and evaluation methods for quantitative coronary angiography are implemented. AWOS is operated by a (menu-in) windows technique. At present an individual digital archive for each patient is based on 525 MB streamer tape. Standardized hardcopy printouts and VHS/S-VHS(CCIR-Standard) are available
