So I went in for an ultrasound.

This is much sharper than an ultrasound would be.

This is an MR suite with a focused ultrasound system.

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.

Doppler ultrasound method This method uses ultrasound and the Doppler effect to measure Q .

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.

So let's first talk about focused ultrasound.

You know all about imaging, right, ultrasound imaging.

According to the Rotterdam criteria, 12 or more small follicles should be seen in an ovary on ultrasound examination.

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

They were the first to be treated by focused ultrasound.

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 the handheld ultrasound is basically surpassing and supplanting the stethoscope.

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

High power ultrasound produces cavitation that facilitates particle disintegration or reactions.

Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

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

Her senior thesis was called Heightened Effects of Thrombolytic Actions Due to Ultrasound .

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.

Industrially, ultrasound is used for cleaning and for mixing, and to accelerate chemical processes.

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

In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws.

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.

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

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.

The blood velocity through the heart causes a 'Doppler shift' in the frequency of the returning ultrasound waves.

The follicles may be oriented along the ovarian periphery, appearing as a 'string of pearls' on ultrasound examination.

One of the neurological conditions that can be treated with focused ultrasound are movement disorders, like Parkinson's or essential tremor.

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.

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.

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

Do you need an ambulance?

Do you have an address?

Do you have an appointment?

Do you need an envelope?

Do you need an envelope?

Do you have an alibi?

Do you have an explanation?

Do you need an umbrella?
