Fluoroscopy or Fluoroscopic X-ray
Fluoroscopic x-ray is a general term for an x-ray technique, which involves use of a fluoroscope to examine a part of the body or function of an organ in real time.

Fluoroscopic techniques are frequently used by radiologists as guidance tools during interventional radiology procedures. Fluoroscopic x-ray can be used to produce serial images, which appear on a video monitor.
