What is fluoroscopy?
Fluoroscopy is a projectional (2D) imaging technique that uses continuously emitted x-rays to perform real-time imaging of a patient. An x-ray tube in the fluoroscope emits an x-ray beam that passes through the patient and falls upon an image intensifier. The image intensifier converts the x-ray radiation into visible light images and amplifies them. These images are then displayed on a monitor and can be viewed or recorded.
