Elementary particles are defined by current physics as quarks, leptons and gauge bosons. A PET (positron emission tomography) scan uses positrons (antiparticles of electrons, which are a type of lepton) to generate a picture of the tissue in question. First, a radioactive isotope that decays by β+ decay (e.g. C11, N13, O15, F18) is incorporated in a organic compound that will localize to the desired tissue. When the compound arrives at the tissue, it can then under go decay and emit a positron. This positron will annihilate with the first electron it encounters, converting both their masses to energy. This energy is expressed as two gamma photons travelling in directly opposite directions so as to conserve momentum. These gamma photons are detected by the PET scanner and when a large number of the atoms are decaying, the computer can use the relative time differential (nanoseconds) between the arrival of the two photons to calculate the position of its origin and render a 3D image of the tissue.

What medical technologies (e.g. PET) rely on the physics of elementary particles?
Medical technologies like PET (positron emission tomography) rely on the physics of elementary particles to visualize and track the behavior of positrons emitted by radioactive tracers in the body. Other examples include proton therapy for cancer treatment, which uses proton particles to target tumors with precision, and PET-MRI scanners that combine PET imaging with magnetic resonance imaging for better diagnostic capabilities.
Is there an app available that can scan pet microchips?
Yes, there are apps available that can scan pet microchips. These apps use the smartphone's camera to scan the microchip and provide information about the pet.
What type of procedure is a PET scan?
cat scan
What is a Diagnostic body scan that is referred to as a ped scan?
Are you talking about a PET scan?
What advantage does the MRI scan have over the Pet scan for the subject?
A PET scan shows what level / stage (if any) the cancer is at. An MRI scan doesn't do this, the reader, looks for abnormalities on the scan which shows up everything in the body.
Can you have a pet scan and bone scan on same day?
Yes, but bone scan has to be completed first.
How much does a pet scan for a dog cost?
A PET scan, or Positron Emission Tomography, is used to scan internal organs for abnormalities, like tumors, or cancer. PET scans for animals may cost hundreds, or thousands of dollars, depending on the size of the animal, and the complexity of the scan.
Can you have braces on during a pet scan?
no
How long does a pet scan take?
A full body PET scan can take 30 to 45 minutes. A scan of a single lamp or a single organ can take as little as 10 minutes.
What is salary for pet scan technologist?
$92,000
How does a PET Scan use Radioisotope decay?
A PET scan uses radioisotope decay by detecting the pair of annihilation photons emitted during the decay process.
Does alcohol affect a PET Scan?
He'll yes.
