> A one day class can cover
...probably not much more than a 1 day C++ course would offer a random person. :)
That's nowhere near what a farmer needs to read much into an ultrasound. It takes a medical student years of learning (medicine) topped by a lot of practice and experience in imaging until they are useful in actually reading an image. And even a 1-2 day course costs thousands of dollars.
It would be a massive expense for very little real life benefit. I'm guessing AI and a remote doctor would do better. I kept reading a lot of good news recently about AI helping with diagnostics in medical imaging so I guess we can't be too far.
