Replacing X-Ray and CT with new imaging would reduce exposure.
HIFU ultrasound arrays are already approved.
Recent research here indicates that longitudinally-polarized Proca waves are usable for Angstrom-scale medical imaging and treatments including tumor lysis and DNA repair.
There are apparently ways to target cancerous cells by their bio signatures in order to only target non-benign tissues.
I'm happy that I kept on with this line of research long enough to realize the medical capabilities (and fire suppression) it enables;
This is due to exposure to the radiation from intra operative x rays.
