What does a gamma camera do?
What does a gamma camera do?
Nuclear medicine uses a special gamma camera and single-photon emission-computed tomography (SPECT) imaging techniques. The gamma camera records the energy emissions from the radiotracer in your body and converts it into an image. The gamma camera itself does not emit any radiation.
Why is a conventional single headed gamma camera is not suited to pet?
Gamma camera PET is markedly inferior to PET imaging with a purpose designed PET scanner, as the scintillator crystal has poor sensitivity for the high-energy annihilation photons, and the detector area is significantly smaller.
Which type of camera is used in gamma camera?
The first scintillation camera or gamma camera proposed by Hal Anger (1957) consisted of a single-pinhole collimator, a 4-in-diameter by 1/4-in-thick NaI(Tl) crystal, seven 1.5-in PMTs, pulse-processing electronics, and an oscilloscope. The image was recorded with a Polaroid-Land camera.
What is the advantage of using more than one gamma camera during a Spect scan?
With the dual-head gamma camera, two opposing detectors are more likely to pick up lesions that may be missed because they fall out of the scope of a single detector, she explains. In addition, recording two facing views provides a means to better localize a lesion’s depth and estimate its size.
Is spect a scintigraphy?
Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information.
What are the benefits of a single-head gamma camera?
Having a single-head gamma camera in your department is a smart way to increase patient satisfaction. The camera’s extra bandwidth will reduce wait times and allow patients to access vital imaging services faster.
What is the size of a gamma camera?
Conventional Gamma Cameras. Two detectors (heads) most common, although single head and triple head cameras are used. Each head has single large NaI (sodium iodide) crystal, up to 40 cm X 60 cm. Typical crystal thickness: 3/8 or 5/8 inch.
Are single-Head SPECT cameras obsolete for cardiac imaging?
As nuclear cardiac imaging technology has evolved, gamma cameras have graduated from single-head to multiple-head detector technology. Although single-head SPECT cameras are not necessarily obsolete, there are an increasing number of drawbacks if you choose to continue using it to diagnose cardiac patients.
Why choose the Siemens ECAM dual-head 180° nuclear camera?
Ideal for oncological applications, the Siemens e.cam Dual-Head 180° nuclear camera features detectors in opposite positions optimized for both whole body and SPECT scanning. The open gantry design permits easy access for patients sitting, standing or on stretchers.
