Since its invention in the 1970th computed tomography (CT) has become an indispensable diagnostic tool in medicine. CT scanning using X-rays was the first clinical tomographic imaging technique which was later complemented by tomographic imaging modalities based on other physical principles, such as magnetic resonance imaging (MRI), positron emission tomography (PET) and single photon emission tomography (SPECT). Today, medical radiology is still the primary application field of computed tomography, but meanwhile this imaging technology has diverted also into other fields of science and engineering, for instance non-destructive testing, flow measurement and small animal imaging.
