Nuclear medicine has existed for many decades. It is an important component of diagnostics and therapy.
The principle is always the same: we know certain metabolic pathways within and between the organs. Low level radiating substances (radiopharmaceuticals) are connected to substances that „go“ this way. A gamma camera detects these substances and a computer converts the information into images. At the same time, the temporal change and spatial distribution of the radiopharmaceutical in a certain area or in the whole body are recorded: that is how a scintigraphy is made. In this way, an abnormal metabolic process can be regionally allocated.
We use modern gamma cameras for nuclear medical examinations. They help to answer all questions posed to nuclear medical diagnostics. Gamma cameras can electronically register the temporal and spatial distribution of the gamma radiation emitted from the patient and send them to a data processing system. This system can process the data appearing in very large quantities within a very short period of time, visualize it and save it. In addition to this, SPECT images (Single Photon Emission Computed Tomography – nuclear medical sliced images) of a very high quality can be developed.
