WebThe most common scintillation camera design was created by Hal Anger in the 1950s. The Anger camera features a single scintillation crystal coupled to multiple photomultiplier tubes which are able to encode the location of the radiation interaction with the crystal. Other designs, such as the multi-crystal design, are less commonly used. WebRadiopharmaceuticals. Radiopharmaceuticals are radioactive drugs.

Gamma camera imaging can be used for diagnosing issues in multiple organs. When imaging a patient using a gamma camera, a gamma emitter, usually technetium-99, is used as the radioactive tracer. It has a short half-life of 6 hours meaning it stays around long enough to be imaged but reduces harm to the patient.

WebGamma correction is sometimes specified in terms of the encoding gamma that it aims to compensate for — not the actual gamma that is applied. For example, the actual gamma applied with a "gamma correction of 1.5" is often equal to 1/1.5, since a gamma of 1/1.5 cancels a gamma of 1.5 (1.5 * 1/1.5 = 1.0). A higher gamma correction value might ... Web18 de set. de 2009 · 3.
