X-ray refers to procedures that use standard x-rays to view parts of the body. This type of exam includes conventional x-rays, tomography (CT) and fluoroscopy. In all three of these procedures, a very low dose of radiation is used. This makes the procedures extremely safe as diagnostic exams.
Fluoroscopy is an imaging technique commonly used by physicians to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope. In its simplest form, a fluoroscope consists of an X-ray source and fluorescent screen between which a patient is placed. However, modern fluoroscopes couple the screen to an X-ray image intensifier and CCD video camera allowing the images to be recorded and played on a monitor.
