The company has also experimented with positron emission tomography, or PET, machines, yet another billable service.
Doctors can look for indications of the disease using positron emission tomography (PET) scans.
Initially, Dr Zeki employed a scanning technique called positron-emission tomography to investigate these regions.
For one thing, fluorine-18 decays far more slowly than other biologically useful positron emitters.
The mobile positron emission tomography (Pet) scanner visits the Bristol Royal Infirmary (BRI) three times a week.
The AMS paper will report the positron-electron ratio in the mass range of 0.5 to 350 Gigaelectronvolts.
FDG, eliminating the need for each hospital to make its own positron emitters in its own cyclotron.
Once these proteins have been highlighted, they can be seen using a sophisticated positron emission tomography (PET) scans.
The positron emission tomorgraphy (Pet) scanner is housed in a mobile unit at the Bristol Royal Infirmary (BRI).
But Dr Zubieta also used positron emission tomography scans during the experiment to peer inside the men's brains.
So for every proton there is an anti-proton, and for every electron there is an anti-electron, or positron.
In traditional Penning traps, the radius of each positron's orbit through the tunnel stays, on average, the same.
The result is that the electron shadow and the positron shadow are separated.

The positron numbers then start to flatten out a possible sign that the hoped-for plunge in positron numbers could come next.
Within the limits of accuracy of the experiment, positron spin-flipping seems to happen at the same frequency as electron spin-flipping.
The Positron Emission Tomography (PET) scanner is an accurate imaging device that zones in on tumours, helping with detection and diagnosis.
In particular, the neutrinos should should have been radiating electron-positron pairs.
The detector allows the machine's operators to work out which particles have been created by the electron-positron collisions, and to follow their patterns of decay.
For decades, physicists at CERN and elsewhere have been trying to overcome these limitations with antihydrogen, which consists of a single positron orbiting a single antiproton.
The group at CERN, called the ALPHA collaboration, was looking at antihydrogen atoms in which a positively charged antielectron, also known as a positron, orbits a negatively charged antiproton.
In addition, Techniques like Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT), and Magnetic Resonance Imaging (MRI) are going to unravel the mystery of the neuron jungle.
But handling the "antihydrogen" - bound atoms made up of an antiproton and a positron - is trickier still because it must not come into contact with anything else.
This creates, as it were, electron and positron shadows.

"As the most precise measurement of the cosmic ray positron flux to date, these results show clearly the power and capabilities of the AMS detector, " Ting said, according to the CERN statement.
CNN: Space station detector gives first clues to 'dark matter'
At the same time, their brains were scanned with positron emission technology (PET), using a radioactive compound that allowed the researchers to visualize where caffeine was going once it arrived in the brain.
FORBES: A Snapshot of Caffeine's Fascinating Effects On The Brain
In a lab at Brookhaven National Laboratory on Long Island, Gene-Jack Wang is injecting overeaters with a radioactive sugar solution and putting them into a positron-emissions tomography machine to see how their brains react to food.
Well, we still don't quite understand the exact nature of dark matter, but highly precise measurements of positron fraction (the ratio of positrons to electrons and protons) do bring us a small step closer to proving the existence of the theoretical material.
In one study in 2004 researchers at the University of Toronto used positron emission tomography scanning to track the brain activity of 14 depressed patients who had successfully been treated with CBT, comparing them with 13 patients who got better by taking only Paxil.
