Gamma camera is a minimally invasive procedure used to create images using crystals of sodium iodine by detecting gamma photons.
A gamma camera (γ-camera) is also referred to as a scintillation camera or anger camera; a device used to image gamma radiation emitting radioisotopes. This technique is also known as scintigraphy. Early drug development and nuclear medical imaging are the applications of scintigraphy, which analyze the various parts of the human body or the distribution of medically inhaled, injected, or ingested radionuclides emitting gamma rays. Gamma camera is used to produce functional scans of the lungs, brain, thyroid, skeleton, liver, gallbladder, and kidneys.
How Does a Gamma Camera Work?
Technetium-99m, a metastable nuclear isomer, is the most commonly used tracer for its relatively long half-life of six hours. It also has the ability to be incorporated into different types of molecules in order to target different systems within the body. As the tracer travels through the body and emits radiation, a crystal tracks its progress that scintillates in response to gamma-rays.
An array of light sensors converts the resulting flash of light into an electrical signal when the crystal is mounted in front of it. Compared to the X-ray, the Gamma camera maps the function and processes of the body instead of the anatomy and structure.
What are the applications of Gamma Camera?
The Gamma Camera tracks the radioisotopes in the area to be scanned and assess how the body’s parts process it. Gamma camera performs several different types of diagnostic scans, such as:
