What is claimed is: 1. A method for prioritized transmission of scalable compressed data, comprising: receiving an interactive prioritization request from a client; prioritizing transmission of the compressed data relative to a bin optimization in response to the interactive prioritization request; and transmitting the prioritized compressed data to the client. 2. A method as defined In claim 1, further comprising transcoding the scalable compressed data into resized precincts for the bin optimization. 3. A method as defined in claim 1, further comprising: providing an interactive prioritization request to a server receiving prioritized compressed data from the server; decompressing the prioritized data; and rendering the decompressed data. 4. A method as defined in claim 3 wherein the compressed data is responsive to a discrete wavelet transform, the method further comprising maintaining a cache responsive to the received prioritized compressed data. 5. A method as defined in claim 4, further comprising maintaining a cache model at the server indicative of the cache responsive to the received prioritized compressed data. 6. A method as defined in claim 3 wherein the rendering is surface rendering, the bin optimization comprising a bin-table generated before, during or after compression of the data. 7. A method as defined in claim 3 wherein the rendering is volume rendering, the bin optimization comprising a bin-table generated after compression of the data. 8. A method as defined in claim 3, further comprising: identifying a volume of interest (VOI); and progressively refining the volume within the VOI towards an increasingly lossless representation. 9. A method as defined in claim 8 wherein contextual background information is provided with a quality fading away from the VOI. 10.

A method as defined in claim 3 wherein the communication protocol allows the client to communicate its cache state to the server. 12. A method as defined in claim 1 wherein the interactive prioritization request comprises a request to progressively receive data corresponding to one of a plurality of tissue types. 13. A method as defined in claim 1, prioritizing comprising re-ordering the same compressed data file on the fly to serve data packets prioritized per the request. 14. A method as defined in claim 1 wherein the bin optimization is responsive to a bin mask, the bin mask corresponding to at least one of scalar intensity and opacity, the method further comprising creating a code-block mask responsive to the bin mask, the code-block mask being indicative of the relevant code-blocks on a sub-band domain. 15. A method as defined in claim 14 wherein the code-block mask is responsive to at least one level of transform applied along the x, y and z directions. 16. A method as defined in claim 1, further comprising: resizing precincts to a size no smaller than a single code-block; and re-layering the resized precincts into packets to emphasize one or more data bins as chosen by the client. 17. A method as defined in claim 16, the bin optimization comprising a bin-table generated during or after data compression, the method further comprising, prior to re-layering, determining from the bin-table the degree to which each precinct contributes to the code-block mask for a bin. 18. A system for prioritized transmission of scalable compressed data, comprising: a database server for receiving an interactive prioritization request from a client and prioritizing transmission of the compressed data relative to a bin optimization in response to the interactive prioritization request; and transmission means in signal communication with the database server for transmitting the prioritized compressed data to the client. 19. A system as defined in claim 18, further comprising: interactive request means for providing an interactive prioritization request to a server; receiver means in signal communication with the interactive request means for receiving prioritized compressed data from the server; a decompressor in signal communication with the receiver means for decompressing the prioritized data; and a rendering engine in signal communication with the decompressor for rendering the decompressed data. 20.
