Interesting you weren't able to find any examples. Here are some quick ones for CT scans in US Canada and UK.

The US maintains the highest hardware capacity of the three nations with roughly 43 scanners per million people and performs around 245 to 290 scans per 1,000 residents per year. non-emergency wait times are 1 to 7 days. The UK has 10 scanners per million people and ~100 scans per 1,000 residents, using centralized triage to keep non-emergency wait times between 1 and 6 weeks for NHS targets. Canada does 160 scans per 1,000 residents and 14 to 15 scanners per million, with wait times of 5 to 9 weeks.

When you consider that the US population is not fully covered by insurance, the number of scans is even higher
