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

So the ultrasonic transducer emits basically an ultrasonic beam that focuses inside the phantom.

So let's first talk about focused ultrasound.

On the right hand side, you see an ultrasonic transducer.

They were the first to be treated by focused ultrasound.

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

This is an MR suite with a focused ultrasound system.

We don't run around emitting ultrasonic squeaks, like bats.

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

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.

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

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

One would send out sound waves that would bounce back.

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

A waveguide is a structure that guides waves, such as electromagnetic waves or sound waves.

Ultrasound, ductography, positron emission mammography (PEM), and magnetic resonance imaging (MRI) are adjuncts to mammography.

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

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.

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

Arterial ultrasound, especially of the carotid arteries, with measurement of the thickness of the artery wall, offers a way to partially track the disease progression.

Traditionally, clinical carotid ultrasounds have only estimated the degree of blood lumen restriction, stenosis, a result of very advanced disease.

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.

We can detect sound waves in the atmospheres of sun like stars.

By intersecting photons with infrasound waves,

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.

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

Additional tests Further diagnostic tests of affected organs may be required, such as nerve conduction studies for neuropathy or an ultrasound of the liver.

Rain announced that she was pregnant again in March 2008 and that the ultrasound indicated the child would likely be a girl.

And the advantage of sound waves is that they actually pass well through water, unlike light.

This is a portable ultrasound.

In addition, all patients in the study received an ultrasound twice which may have influenced allocation of co interventions.

However, the standard method of diagnosis is through ultrasound imaging performed in the emergency room may be equally accurate in children.

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.

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

And this is, in 2004, the FDA has approved MR guided focused ultrasounds for the treatment of symptomatic uterine fibroids.

Now the smartphones that we're already carrying can clearly have diagnostic devices like ultrasounds plugged into them, and a whole array of others, today, and as sensing is built into these, we'll be able to do vital signs monitor and behavioral monitoring like we've never had before.

In a mode that uses surface acoustic waves (SAW), the sensitivity is greatly increased.

It is an amazing tool called astroseismology where we can detect sound waves in the atmospheres of stars.

listen in the coffee bar to how many channels of sound can I hear?

This is much sharper than an ultrasound would be.

For years, soundcards had only one or two channels of digital sound (most notably the Sound Blaster series and their compatibles) with the exception of the E MU card family, the Gravis GF 1 and AMD Interwave, which had hardware support for up to 32 independent channels of digital audio.

You know all about imaging, right, ultrasound imaging.

And so one of the tools that we can use to sample the oceans is acoustics, or sound waves.
