Abstract:
1. 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 reconstructing a diagnostic quality image, from the progressively received image data, using the reconstruction software on the user's computer, wherein progressively transmitting the requested data over the network comprises: recomposing the image into a pyramidal structure comprised of layers, said layers ranging sequentially from a layer having the least amount of data to a layer having the most data; and transmitting the layers making up the pyramid individually starting with the layer with the least amount of data to enable the user to view a progressively improving image to decide on further transmission of the image, further comprising: providing a first layer with reduced resolution in the pyramidal structure; providing remaining layers that contain residual values with increased resolution; progressively receiving the data used to provide images based on the received data of progressively improved resolution; and using adaptive slicing and entropy coding and decoding of each slice for progressively transmitting the requested specific image data, wherein said entropy coding generates a residual matrix.
