Distant diagnostic services require the exchange of medical images and medical data in the form of specialized patient records. Given that multiple images for one patient are often used by these services, considerable demands are placed on support applications implementation, because of the processing and transmission infrastructure limitations found on isolated rural areas. This work proposes to evaluate the performance of medical image compression for such constrained scenario, based on the JPEG 2000 compression standard, in order to improve distant diagnostic services usability. Separate groups of 1 to 15 high resolution gray scale and color cytology images of fixed dimensions were compressed in one file, applying different possible bitrates, tile size and code-block size, for six discrete wavelet decomposition levels. Experimental results show that the adjustment of these parameters, allows compressing the worst data load case (135 MB with moderate lossy compression) in around two minutes, on an average current PC.
