What is Optical Scanner? - Definition from Techopedia

WebMagnetic resonance imaging (MRI) scans use magnets and radio waves. Both produce still images of organs and body structures. PET scans use a radioactive tracer to show how an organ is functioning in real time. PET scan images can detect cellular changes in organs and tissues earlier than CT and MRI scans. WebThe term “ computed tomography ,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images, or “slices.”
