{{Main|Fluoroscopy}}

[[Fluoroscopy]] is an imaging technique commonly used by physicians or [[radiation therapist]]s to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope.<ref name=":1">{{cite journal |last1=Davros |first1=William J. |title=Fluoroscopy: basic science, optimal use, and patient/operator protection |journal=Techniques in Regional Anesthesia and Pain Management |date=April 2007 |volume=11 |issue=2 |pages=44–54 |doi=10.1053/j.trap.2007.02.005 }}</ref> In its simplest form, a fluoroscope consists of an X-ray source and a fluorescent screen, between which a patient is placed. However, modern fluoroscopes couple the screen to an [[X-ray image intensifier]] and [[charge-coupled device|CCD]] [[video camera]] allowing the images to be recorded and played on a monitor. This method may use a contrast material. Examples include cardiac catheterization (to examine for [[coronary circulation|coronary artery blockages]]), embolization procedures (to stop bleeding during [[hemorrhoidal artery embolization]]), and barium swallow (to examine for [[esophageal disorder]]s and swallowing disorders). As of recent, modern fluoroscopy utilizes short bursts of x-rays, rather than a continuous beam, to effectively lower radiation exposure for both the patient and operator.<ref name=":1" />
