examination by means of fluoroscope, employing imaging intensification or flat panel detector.
a medical imaging technique that uses X-rays to create a real-time video of the inside of the body
Fluoroscopy
portable fluoroscopy, consists of a fluoroscopic x-ray tube and image receptor assembly centered to each other. portable x-ray machine.
c-arm
grid that is integral part of the Xray, located below the table top and above the cassette receptor tray. decreases scatter radiation reaching the IR, improves image quality, moves during exposure so no grid lines show
