> Still being run through clinical trials at UW Medicine, the procedure called _ burst wave lithotripsy _ uses an ultrasound wand and soundwaves to break apart the kidney stone
> Ultrasonic propulsion is then used to move the stone fragments out, potentially giving patients relief in 10 minutes or less
One of their demo videos explains how inverting the scattering caused by the occluding body yields the mass-density at least (?). [Radio]Spectroscopy and quantum crystallography may have additional insight for tissue identification with low-cost NIRS sensor data?

Could NIRS help with this targeted ultrasound procedure, too?
