Tomography (PET) and Single Photon Computed Tomography (SPECT). For these types of nuclear imaging, one administers a radioactive substance to the patient and detects emitted radiation with a detector system, e.g., with a ring detector for PET or with one or several gamma cameras for SPECT...
Gamma cameras are primarily used by physicians and medical practitioners who specialize in the field of nuclear medicine. Nuclear medicine is a unique medical specialty wherein low-level radioactive materials (called radionuclides or radiopharmaceuticals) are used to generate images of the organs, bones...
In the illustrative embodiment shown in FIG. 1, the medical imaging system 10 receives signals corresponding to events detected by a sensor such as a camera detector 12. In one embodiment, the camera detector 12 is a gamma camera for nuclear medicine imaging. Upon detecting gamma rays by the...
Nuclear medicine is a unique medical specialty wherein radiation is used to acquire images which show the function and anatomy of organs, bones, or tissues of the body. Radiopharmaceuticals are introduced into the body, either by injection or ingestion, and are attracted to specific organs, bones...
