A Compact Medical Image Network Using PC-Workstation

Abstract

The display of diagnostic images are accomplished in the radiology department using a network and three different type image workstations including a 1ow pixel resolution with three 512×512×8bit non-interlace display, and high resolution image work station with single(three after integrated)1024×1024×8 bit non-interlace display. Both low and high resolution workstations use a PC 9801VX desktop computer (80286) with a 20 MB hard disk and use a PC/AT (80286) desk-top computer with 30 MB hard disk. The workstations provide the user with basic image processing functions by using an ACRTC (advanced CRT controller) which was attached to the display control board and include zoom, scroll, image reversal, contrast enhancement, calibrated distance and pixel density measurements. All image processing functions are performed in real time using the interactive mouse device. The workstation has a self contained network (MS-network) interface use an 80186 processor and requires an Ethernet coaxial cable in order to access the baseband network. The images are provided from the server station with a desk-top computer and an 1.2 GB optical disk.
