Positronic Emission Tomography (PET Scanner)
Positrons are the antiparticle to an Electron.
Basically, a radioactive isotope is injected into the patient's blood, the isotope being unstable desires to reach stability, so a proton inside the nucleus is converted into a neutron by 'shedding' off a positron.
After a few millimetres, the positron will encounter an electron. When these two particles collide they then 'annihilate' each other, a cocktail of photons are then given off in the form of gamma-rays.
The sensors around the patient have photo sensitive plates that detect this gamma radiation, this then generates an electric current which via heavy computing is converted readily into an image.
What else can I help you with?
Why need positron?
Positrons are important in medical imaging techniques like PET scans because they allow us to detect and visualize metabolic processes in the body. They also play a role in fundamental physics research, as their interactions with electrons can provide insight into the fundamental forces of nature.
The first medical imaging technique to be developed was a what?
The first imaging technique for the human body was discovered by Wilhelm Röntgen in 1895.
What medical imaging technique is used for Multiple Sclerosis?
MRI
What medical imaging technique is used to determine if a person has multiple sclerosis?
An MRI scan
What medical imaging technique will a physician order to determine if such plaques are present in signs of sclerosis?
Magnetic Resonance Imaging (MRI) or Nuclear Magnetic Resonance Imaging (NMRI)
What is the first medical imaging technique?
The first medical imaging technique is X-ray imaging, discovered by Wilhelm Roentgen in 1895. X-rays are a form of electromagnetic radiation used to create images of the inside of the body, allowing healthcare professionals to visualize bones and detect certain conditions.
Corneal topography also known as videokeratography is a medical imaging technique to map what body part?
Eye
What is the medical term for diagnostic technique that projects and retrieves high frequency sound waves?
ultrasound imaging
What medical imaging technique would an obstetrician use to look at baby development?
They use an ultrasound machine.
Which medical imaging technique depends on the use of xrays moving in an arc around the body producing a cross sectional image?
Magnetic Regonance Imaging (MRI)
Is a PET a laboratory procedure?
PET (Positron Emission Tomography) is a very modern and expensive medical imaging technique.
Which medical imaging technique will the physician problably use to measure the fetus head size in her womb?
ultra sound
