Sounds like an overhyped story....Don't MRI's work that way....and you have to move thru a tube to be scanned.....

Have they just built a super duper MRI unit?

Medical field should be a market.

RE: "Have they just built a super duper MRI unit?"
No Ernest. Entirely in every way from a physics stand point different.
MRI works on the principle of pumping very selective high energy magnetic radiation through a body which "excite the protons within say a person's body within a small area, which then change energy levels (obviously with the electron shells playing into the process) which then radiate outward and are picked up by the MRI sensors and feed into very complex computer's to run their algorithms, and finally plot out on a display or other recording device, slice by slice as the MRI scans take place.

The process being described here, regarding the laser, is where an actual laser beam interacts with molecules on say one's skin, and then a specialized spectroscope (I'm clueless as of yet exactly what type would be incorporated, perhaps an array of say IR, and UV spectroscopy units, would then read sample molecules from the air, and analyze them. Just like you would pump a sample in a spectroscopic unit via. a hypodermic needle.
Short answer. To totally different types of diagnostic tools using totally different type of electronics and sensors.

Don't MRI's work that way

MRI = magnetic resonance imaging

MRI electromagnetic fields are in the RF range of tens of megahertz (often in the shortwave radio portion of the electromagnetic spectrum)radiated within the coil itself.

Megahertz is a measurement of time equal to one million hertz or one million cycles per second.

Laser = light amplification by stimulated emission of radiation

Lasers appear to range from the Infrared light spectrum at 1540 nm (nanometer) through visible light into the Ultraviolet spectrum of 238 nm (UV-C)

A nanometer is a measure of distance equal to one billionth of a meter.

---

one nanometer is approximately equal to .3 hertz

one megahertz is approximately equal to 300 meters

It runs on beans, it runs on laser beans.
