Abstract--We present a novel 3-D scalable compression method
for medical images with optimized volume of interest (VOI)
coding. The method is presented within the framework of inter-
active telemedicine applications, where different remote clients
may access the compressed 3-D medical imaging data stored
on a central server and request the transmission of different
VOIs from an initial lossy to a final lossless representation. The
method employs the 3-D integer wavelet transform and a mod-
ified EBCOT with 3-D contexts to create a scalable bit-stream.
Optimized VOI coding is attained by an optimization technique
that reorders the output bit-stream after encoding, so that those
bits belonging to a VOI are decoded at the highest quality possible
at any bit-rate, while allowing for the decoding of background
information with peripherally increasing quality around the VOI.
The bit-stream reordering procedure is based on a weighting
