What is a gamma camera used for?
Diagnostic Procedures The gamma camera, also called scintillation camera, is the most commonly used imaging device in nuclear medicine. It simultaneously detects radiation from the entire FOV and enables the acquisition of dynamic as well as static images of the area of interest in the human body .
What is the most efficient energy range for gamma cameras?
Deteriorating intrinsic spatial resolution becomes the limiting factor at lower energies. Because of these tradeoffs, the optimal γ-ray energy range is approximately 100 to 200 keV for most gamma cameras.
What is gamma camera machine?
A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy.
What are dangers of gamma rays?
The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.
What is the principle of gamma camera?
1. The Anger gamma camera. The principle of radiation detection is based on the interaction of these radiations with the matter. When a gamma photon enters in interaction with a detector material, it loses its energy mainly in the form of ionizations or excitations.
What is sensitivity of gamma camera?
Sensitivity of a gamma camera is defined as the number of counts per unit. time detected by the device for each unit of activity present in a source. It. is normally expressed in counts per second per microcurie (cps/mCi).
What damage can gamma rays cause?
Gamma rays can pass completely through the human body; as they pass through, they can cause damage to tissue and DNA..
How are gamma rays good?
Gamma rays kill microbes, and are used to sterilise food so that it will keep fresh for longer. This is known as “irradiated” food. Gamma rays are also used to sterilise medical equipment.
Are gamma rays helpful?
Gamma rays can be helpful as well as harmful (and are very unlikely to turn you into the Hulk). To destroy brain cancers and other problems, medical scientists sometimes use a “gamma ray knife.” This consists of many beams of gamma rays focused on the cells that need to be destroyed.
What are the basic components of gamma camera?
The main components of a gamma camera are:
- the sodium iodide crystal;
- the collimator; and.
- the photomultiplier tubes.
What is spatial resolution gamma camera?
Spatial resolution of a gamma camera is defined as the ability of the overall gamma camera system to accurately determine the original location of a gamma ray on an X-Y plane, with and without scatter medium [1–3].
Are gamma rays harmful or helpful?
What are some positive effects of gamma rays?
Positive applications of gamma rays include cancer treatment through radiation, measurement and tracking of fluid flows, resource exploration, sterilization of medical equipment, pasteurization and geodesic surveys.
