1. A method of acquiring, storing, retrieving and displaying a medical diagnostic image comprising the steps ofa) acquiring said image having a first resolution, and translating said image to a predetermined digital format,b) storing said digitized image in a computer memory at a first location,c) requesting said image from a user-operated terminal having a predetermined resolution limit and located at a second location,d) creating from said digitized image, at said first location, by means of a first algorithm, a patterned and compressed representation thereof,e) transmitting from said first location to said terminal a first portion of said stored patterned representation,f) reconstructing, at said terminal, by means of a second algorithm, from said first portion of said patterned representation, a first displayable representation of said diagnostic image, said first displayable representation having a second resolution no greater than said first resolution,g) displaying said displayable representation at said terminal,h) transmitting from said first location to said terminal an additional portion of said patterned representation,i) reconstructing, at said terminal, by means of a third algorithm, from said additional portion of said patterned representation, an improved displayable representation of said image, said improved displayable representation having a third resolution greater than said second resolution,j) repeating steps g), h) and i), thereby progressively increasing the resolution of said displayed representation until said displayed resolution attains the less ofsaid first resolution of said image orsaid predetermined resolution limit of said terminal.
