Automated high definition/resolution image storage, retrieval and transmission system
DCFirst Claim
1. A medical image storage, retrieval and transmission system providing simultaneous automated access to an image data base by a plurality of remote subscribers upon request over a communications network, said system comprisingimage digitizing means forming a first digitized representation of said image,first data compression means generating from said first digitized representation a low-loss second digitized representation of said image,image data storage and retrieval means comprisingmeans to receive and store said second digitized representation and to selectively provide said second digitized representation to data channel compression means compressing said second digitized representation to form a third digitized representation, andtelecommunication means including means to selectively transmit said requested third digitized representation to a requesting remote visual display terminal, said telecommunication means initially telecommunicating a first portion of said third digital representation, said remote terminal including means to convert said first portion of said third representation to a visual image having an initial resolution less than a resolution limit of said requesting terminal, said telecommuncation means subsequently telecommunicating a second portion of said third digital representation, said second portion usable with said first portion to form an image having a resolution intermediate said initial resolution and said resolution limit.

Abstract
An automated high definition/resolution image storage, retrieval and transmission system for use with medical X-ray film or other documents to provide simultaneous automated access to a common data base by a plurality of remote subscribers upon request, the automated high definition/resolution image storage, retrieval and transmission system comprising an image scanning and digitizing subsystem to scan and digitize visual image information from an image film or the like; an image data storage and retrieval subsystem to receive and store the digitized information and to selectively provide the digitized information upon request from a remote site, a telecommunication subsystem to selectively transmit the requested digitized information from the image data storage and retrieval subsystem to the requesting remote visual display terminal for conversion to a visual image at the remote site to visually display the requested information from the image data storage and retrieval subsystem.
