Medical Imaging Modalities

Medical imaging modalities are used in medicine and are based on an array of energy sources which include light, X-rays, electrons, radionuclides, lasers, ultrasound and nuclear magnetic resonance (NMR). Imaging modalities used in radiology technologies are mammography, radiation therapy, CAT SCANS and radiofrequency (RF) X-ray units.  Medical imaging modalities can be combined through image fusion to provide a complete picture of the human body.  For an example of an image fusion is the hybrid of positron emission tomography (PET), a nuclear medicine method that images metabolic processes in 3-D, combined with computed tomography (CT) to create a PET/CT imaging to locate cancer sites.
