MIT Scientists Can Look at Your Insides From a Distance

A series of lasers acts like an ultrasound without requiring physical contact.

Scientists have developed a system of lasers that can probe inside the human body, much like an ultrasound, but from a distance.

The system can accurately image what’s going on inside a person’s body up to a depth of about six centimeters, according to an MIT press release. While that may not seem like much, it’s still an important first step in removing physical contact from ultrasound scans, as that can sometimes introduce variability in a doctor’s readings.

Are Imaging Scans Worth It?

By Jacob Teitelbaum – Re-Blogged From Newsmax Health

We’ve known for decades that spinal X-rays, MRIs and CT scans add very little information about back pain. They most often don’t tell doctors whether the pain is coming from the spine or from disc, arthritic or bone disease (though they may reveal if the problem can be fixed with a chiropractic adjustment.)

Research also shows that, if back pain is present, radiologists tend to interpret x-ray results as confirming the presence of a host of horrific (and scary-sounding) problems. Yet remarkably, if those same radiologists are shown X-rays and MRIs from both healthy people and those with back pain, they can’t tell one group from the other!
