I’m surprised reports were generated quicker when the radiologist worked with the X-ray tech. Back when I did x-rays, a quick radiologist could report a set of films in about a minute. I could X-ray 6 patients per hour (whilst doing data entry, billing, walking them to the room etc as well). I doubt I’d have been much more than twice as fast if the admin was skipped.
Reduced patient wait time (lower latency) was prioritized over how many X-Rays were processed per hour.
E.g. it wouldn't matter how fast the X-Ray specialist was working if the results were getting back to the patients in big batches, sent once an hour, because the patients might not live long enough to get them.
