So this is a CAT scan Computer Aided Tomography.

He said, Yeah, we're going to need to do a CT scan of your chest.

You see a CT scan where cancer is in the liver.

And this is our beast of burden this is a Computer Tomography machine, a CT machine.

I went in for the CAT scan, and it turns out there were five of these things in both my lungs.

You then have some anatomic descriptions, you get that CT scan There's a three centimeter mass in the liver.

Advanced medical imaging with computed tomography (CT) or magnetic resonance imaging (MRI), and with single photon emission computed tomography (SPECT) or positron emission tomography (PET) can be used to help exclude other cerebral pathology or subtypes of dementia.

The average radiation dose from an abdominal X ray is 0.7 mGy, that from an abdominal CT scan is 8.0 mGy, that from a pelvic CT scan is 6 mGy, and that from a selective CT scan of the abdomen and the pelvis is 14 mGy.

They did a CT scan.

It's going to go inside something that we use in CAT scans and MRIs of whatever is their good arm, to make silicon rubber, then coat it, and paint it in 3D exact mirror image of their other limb.

So the strategy here is this is actually a CT scan, an X ray and we go layer by layer, using computerized morphometric imaging analysis and 3D reconstruction to get right down to those patient's own kidneys.

And that's actually a completely computer generated rendering of her face.

So unlike the CAT scans, X rays, thalliums, for women whose breast is in the way of looking at the heart, every time we order something that has even a small amount of radiation, we say, Do we really need that test?

And you can see this PET scan of a mouse what we call a pet PET.

We prototyped by CAT scanning the brain out of this animal.

Imagine this collected awareness of the individual computed and reflected across an entire lifespan.

The first human to human heart transplant was performed by cardiac surgeon Christiaan Barnard at Groote Schuur Hospital in December 1967, Max Theiler developed a vaccine against yellow fever, Allan McLeod Cormack pioneered x ray computed tomography, and Aaron Klug developed crystallographic electron microscopy techniques.

And the cardiac PET scan shown on the lower left, the blue means no blood flow.

She had three kids under the age of 12, and this is her CT scan.

I was in a doctor's office last CAT scan, and there was a Reader's Digest, October 2002.

There is no evidence of complex antimatter atomic nuclei, such as antihelium nuclei (i.e., anti alpha particles), in cosmic rays.

She was resuscitated, stabilized, whisked over to a CAT scan suite right next to the emergency room, because they were concerned about blood clots in the lung.

For a non rotating black hole, this region takes the shape of a single point and for a rotating black hole, it is smeared out to form a ring singularity lying in the plane of rotation.

And the CAT scan revealed no blood clots in the lung, but it showed bilateral, visible, palpable breast masses, breast tumors, that had metastasized widely all over the body.

These minor changes in blockages caused a 300 percent improvement in blood flow, and using cardiac positron emission tomography, or PET, scans, blue and black is no blood flow, orange and white is maximal.

I joke, but I only half joke, that if you come to one of our hospitals missing a limb, no one will believe you till they get a CAT scan, MRI or orthopedic consult.

And what I'm going to do in the next five minutes is take you through a process where we tried to create a reasonably photo realistic computer generated face, using some computer graphics technology we've developed, and also some collaborators at a company called Image Metrics.

And in fact, this technology has gotten so developed that this creature this is a moth this is the moth in its pupa stage, and that's when they put the wires in and they put in the computer technology, so that when the moth actually emerges as a moth, it is already prewired.

The problem is that, if I'm this doc, and I get your CT scan today and you've got a two centimeter mass in your liver, and you come back to me in three months and it's three centimeters, did that drug help you or not?

Aripiprazole doses ranging from 0.5 to 30 mg administered once a day to healthy subjects for 2 weeks produced a dose dependent reduction in the binding of 11C raclopride, a D2 D3 receptor ligand, to the caudate and putamen detected by positron emission tomography.

And then with four screws, we put in a frame, then we snap in the device and we run with wires the one shown in green will go to the surface of the brain with electrodes, to the epileptic focus, the origin of the epilepsy, where we can sense the electrical signal and have computer analysis that tells us when to hit it with some electrical current to prevent the clinical manifestation of the seizure.
