Abstract: An interactive system for obtaining data for diagnostic purposes from a server having access to stores of said data wherein the server supplies the data and software to a data requesting user that enables the user to receive the data progressively so as to decide during the receipt of the data what portions of the data are to be received thereby decreasing the time required to receive the data and that enables the user to load the software to process the supplied data.

Abstract: An interactive method for allowing a user to obtain image data for diagnostic purposes from a server having access to stored data, comprising: connecting a user's computer to the server over a communication network; receiving from the server image reconstruction software for the user's computer; requesting specific image data for transmission from the server to the user's computer; progressively transmitting the requested specific image data over the network from the server to user's computer; and repeatedly reconstructing diagnostic quality images, from the progressively received image data, at different quality levels, using the reconstruction software on the user's computer.
