The file format is reasonably cursed (header fields to indicate endian-ness, multiple internal metadata tables, and it's a container format so you can encode the image data using any one of 6-8 codecs - or just include a link to the TCP stream).
I haven't used the network protocol, but having some way to only bring the required pixel data across the network is pretty important - uncompressed CT scans are often hundreds of megabytes and the standard was developed before ethernet was widespread.
- evulhotdog 4y agoA standard uncompressed CT slice is ~512kb, so multiply that by the number of slices. Angiograms tend to be much larger as well.
- danielheath 4y agoI'm starting to see 1000-slice scans more often, but I hear 100-400 was more common back when size was a pressing concern.
- evulhotdog 4y agoApparently you haven’t seen what the Toshibas/Canons can pump out. Some can be 6000 slices or more.
