Find Multiple Images Of The Body Organs With The Help Of Nuclear Medicine Gamma Camera

Under the process of nuclear medicine imaging, radiopharmaceuticals are taken internally (intravenously or orally). Then external detectors called nuclear medicine gamma cameras precisely capture and form images from the radiation emitted by the radiopharmaceuticals. On the other hand, x-ray radiation is passed through the body to produce images. Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma camera. It is a 3D tomographic technique that applies gamma camera from many projections.

Position emission tomography (PET) applies coincidence detection to image functional processes. The images yield information about the anatomy, and physicians can interpret the images to determine the cause of a given disease. Such medicine involves small amount of radioisotopes as tracers to diagnose disease. These tracers emit characteristics radiations and special electronic instruments such as scintillation or a gamma camera to display these emissions into images. A nuclear medicine gamma camera is associated with the computer where images can be analyzed well.    

In the gamma camera, gamma ray radiation is converted into light photons by a collimator and a crystal. A wide array of techniques is there to assist diagnose and mange disease. Blood samples are tested with radioactive labeled probes that can detect the presence of specific pathogens. The resulting images or scintigrams can be two-dimensional or they can be more complex in three dimensional slices. There are some of the known techniques such as radioimmunoassay and immunoradiometric assay, molecular method, nuclear imaging, nonspecific organ imaging, scintigraphy. The SPECT uses a rotating nuclear medicine gamma camera to produce images from multiple angels of the organ under study.
