I left radiotherapy for this reason: they haven't the faintest idea what they are doing, and are constrained by whatever manufacturers managed to get the FDA to approve, which is 20 year old tech at best. Not that radiotherapists/logists know how to deal with modern tech... A small hint: our software repo was migrated TO svn in 2014.

When people do 'AI' in radiology, they mean making little with scripts in Tensorflow. Sure, it's a beginning, but I've seen entire institutes being unable to get to grips and move past that stage. You wouldn't be able to tell from their slides, of course.
