A New Laser Technology Can See Inside Our Bodies Like Never Before

While X-rays can produce harmful radiation, a new technique using laser-induced sound waves provides highly detailed images of the structures in our bodies.

Photoacoustic imaging is an emerging imaging technique that shoots micro-pulses of laser light at a specimen or body part, which selectively heats up parts of the tissue causing them to expand, and generate waves of pressure –– a.k.a. sound waves.

Ultrasonic sensors are situated to capture these microscopic changes, and a processing software then reconstructs the image based on what the sensors “hear.” The speed of the laser can be adjusted depending on what type of tissue one would like to visualize.

The photoacoustic imaging technique is beginning to take off in both the medical and scientific worlds, as it provides us with super clear, incredibly detailed images of the human body and the structures inside it.

Not to mention, the imaging technique causes no discomfort and there is no dangerous ionizing radiation involved, making it a desirable alternative to more traditional imaging, like a CT scan, ultrasound, or a PET scan.

Not only can this new imaging technology be used to image tissues at extremely high resolution, you can also introduce a foreign material, like a contrast dye or a specially designed nanoparticle, to see things you might not be able to otherwise.

Although the technique has been around for more than a century, photoacoustic imaging is just starting to be clinically explored as an alternative and prototype clinical machinery is in development.







This looks like very promising tech. I hope it gets ready for prime time really soon.

It existed in a galaxy far far away and a long time ago ... it is called a light saber ... painless surgery ;-)

Is that why Luke yelled when Darth Vader cut off Luke's hand (he asked innocently)?

No joke intended, but Moses had a first name?

Amos Moses was a Cajun, he live by himself in the swamp. He hunted alligators for a living, he'd just knock 'em in the head with a stump.

Now everyone blamed his old man
For making him mean as a snake
When Amos Moses was a boy
His daddy would use him for alligator bait
Tie a rope around his neck and throw him in the swamp
Alligator bait in the Louisiana bayou


He could trap the biggest, the meanest alligator
And he'd just use one hand
That's all he got left 'cause an alligator bit it
Left arm gone clear up to the elbow






See, "Father/son binding."


LOL




:-P

I couldn't make out the words well (old Yankee that I am) but I got right into knowing that guitar rhythm from the start.

Quick swamp story.  The Sheriff knew a fellow was poachin deer.  But he could neverr catch him at it.  He would sneak up on the trailer and every damn time, the fellow would look out the door and say "C'mon in, I got hot coffee".  And he would.  Finally, the sheriff retired and asked the old guy how he when he was there. 

The old poacher said "I did that every morning.  When ya camin in, I didn't go huntin.  When ya didn't, I went out a got a deer.

LOL!
