The Invention of Computed Tomography In 1969, Dr. James Ambrose, a neuroradiologist from Atkinson Morley's Hospital in London, got a call from an engineer he had never met named Godfrey Hounsfield from EMI laboratories Hounsfield called this technology a CT (computerized tomography) scan, also called a CAT scan (computerized axial tomography). It was especially useful for looking at head injuries and brain.. Sir Godfrey Hounsfield, the inventor of computed tomography In London, in fall 1971, a radiologist and an engineer found themselves jumping up and down for joy - as one of them later recalled - like football players who had just scored a winning goal
Source: Terese Winslow. The 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—of the body A CT scan or computed tomography scan (formerly known as computed axial tomography or CAT scan) is a medical imaging technique used in radiology to get detailed images of the body noninvasively for diagnostic purposes. The personnel that perform CT scans are called radiographers or radiology technologists.. CT scanners use a rotating x-ray tube and a row of detectors placed in the gantry to. Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is sometimes called computerized tomography or computerized axial tomography (CAT).. The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record). Each picture created during a CT procedure. CT scan: A computerized tomography (CT) scan combines a series of X-ray images taken from different angles and uses computer processing to create cross-sectional images, or slices, of the bones, blood vessels and soft tissues inside your body. CT scan images provide more detailed information than plain X-rays do Computed tomography (CT scan or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body.
