Hey, I heard about how utility pole inspecting helicopters are able to tell the good/rotten state of wooden telephone poles by the reverb pattern of sound waves coming off the poles from the rotors -- it seems to me the whole field of non-invasive sensing (and using existing/ambient emission sources) is getting pretty impressive.

And yet CT scans that dose patients with radiation are still standard of care.

You get a lot more detailed information out of a CT scan

Not more detailed than an MRI. And the longer we push CT scans, the longer we delay the advancement of less invasive technologies.
