X-ray images are usually in a TIFF format with no or very little image
quality loss. Uncompressed TIFFs are about 10MB in size for reasonable
reproduction of an 8x11 print and, as you know, some X-ray pictures are
about 3 times that size.
Lossless compression (like JPEG) can shrink these images to about 750K size;
however it is possible to acquire artifacts, which is not acceptable for
medical imaging.
The best test is a benchmark - see what compression does Citrix provide (not
as good as static JPEG, since they are probably using RLE) and whether
doctors can handle possible liability, since their X-ray diagnoses can be
hindered by artifacts of compression!
Although original program is acceptable by doctors, since Citrix image
compression is not something you can control, your implementation might not.

PS
Obviously at high magnification and partial image display you can get a good
quality at reasonable bandwidth consumption.

There is a software package entitled JPACS that is used to allow physicians to view x-ray images, and I have installed on a Metaframe 1.8 server FR1 running NT 4. Are there any "tweaks" I could employ to help speed up the presentation of these images or is doing something like this just a bad idea over Citrix (like animation) is?
