You aren’t far off. Costs vary hugely depending on machine spec and how it’s run. A gold plated set of contracts with specified uptime is not cheap, but it is easily a saving when you can’t bill thousands an hour due to an outage. Spreading the cost over 10 years is a little misleading. Scanners can last 15 years without too much drama, but upgrades every 5 or so years which cost hundreds of thousands can be expected. An outpatient scanner will not get 20 hours usage per day where I live, but a hospital one could. Staff costs, as you note, are huge and dwarf the scanner costs over its lifetime. I wouldn’t be surprised if staffing was a 10x multiplier on scanner costs.
