What about ultrasound?

It's actually emitting ultrasound low level ultrasound that's about 100,000 vibrations per second.

Okay, so let's talk a little bit about ultrasound, the force of ultrasound.

This is a portable ultrasound.

I'd like you to have an ultrasound.

So let's first talk about focused ultrasound.

So I went in for an ultrasound.

You know all about imaging, right, ultrasound imaging.

This is much sharper than an ultrasound would be.

This is an MR suite with a focused ultrasound system.

They were the first to be treated by focused ultrasound.

So the handheld ultrasound is basically surpassing and supplanting the stethoscope.

So she elected to undergo a focused ultrasound procedure in 2008.

This is Libby, or actually, this is an ultrasound image of Libby.

And if you took an ultrasound of that area, it would look great.

Bear in mind this was an ultrasound, so it would have been moving images.

But ultrasound can be shaped to be anything in between, because it's a mechanical force.

One of the neurological conditions that can be treated with focused ultrasound are movement disorders,

One is the focused ultrasound, and the other one is the vision enabled magnetic resonance imaging.

Ultrasound generates more biopsies that are unnecessary relative to other technologies, so it's not widely used.

So this idea of harnessing focused ultrasound to treat lesions in the brain is not new at all.

First, ultrasound we're very familiar with it from physical therapy it's also now being used to treat cancer.

Using 3D ultrasound technology, we can now see that developing babies appear to smile, even in the womb.

We're also starting ancillary health care technology training programs training people in echocardiography, cardiac ultrasound, those kinds of things.

We can prevent, or have the earliest detection possible, for breast cancer with an ultrasound device given to the patient.

But you may not know that he tried to perform lobotomies in the brain, noninvasively, with focused ultrasound in the '50s.

All those I've indicated have already been shown to be successfully treated by focused ultrasound relieving the pain, again, very fast.

I'm going to show you a couple of images from a very diverting paper in The Journal of Ultrasound in Medicine.

It is approved under an FDAlDE at the University of Virginia in Charlottesville using focused ultrasound to ablate a point in his thalamus.

So you can change the intensity, the frequency, the duration, the pulse shape of the ultrasound to create anything from an airbrush to a hammer.

I'm going to go way out on a limb and say that it is the most diverting paper ever published in The Journal of Ultrasound in Medicine.

Here is an example of an abdominal ultrasound, and also a cardiac echo, which can be sent wireless, and then there's an example of fetal monitoring on your smartphone.

So we picked up on that and we said, You know, we now have the ability to look inside human beings with these special catheters called IVUS intravascular ultrasound.

An effect happens in the air, it's a corrupting effect of the sound the ultrasound in this case that's emitted, but it's so predictable that you can produce very precise audio out of that effect.

And I'm sitting in a waiting room some time later for an ultrasound, and all six of these doctors actually show up in the room at once, and I'm like, Uh oh, this is bad news.

And basically everything we know about percussion, which you can think of as an ultrasound of its day organ enlargement, fluid around the heart, fluid in the lungs, abdominal changes all of this he described in this wonderful manuscript

It wasn't until the invention of the MR and really the integration of MR with focused ultrasound that we could get the feedback both the anatomical and the physiological in order to have a completely noninvasive, closed loop surgical procedure.

That same interaction that we just did with the ultrasound will likely have real time image processing, and the device will say, Up, down, left, right, ah, Eric, that's the perfect spot to send that image off to your doctor.

There is a unique opportunity now with focused ultrasound guided by MR, because we can actually think about prostate lumpectomy treating just the focal lesion and not removing the whole gland, and by that, avoiding all the issues with potency and incontinence.
