WebA continuous X-ray beam is passed through the body part being examined. The beam is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail. Fluoroscopy, as an imaging tool, enables physicians to look at many body systems, including the skeletal, digestive, urinary, respiratory, and reproductive systems. WebThe X-rays are produced in a vacuum tube that contains a heater, anode, and cathode. These components are made of high-grade metals that can sustain high temperatures without getting damaged. Like in any diode tube, the electrons are designed to flow from the cathode to the anode. The cathode is connected to a high-voltage DC electricity source. WebMar 23, 2024 · Computed tomography (CT), also known as, especially in the older literature and textbooks, computerized axial tomography (CAT), is an imaging modality that uses x -rays to build cross-sectional images ("slices") of the body.
