D) LEDs

Question

Quizplus · Accepted Answer

Digital fluoroscopy systems with an image intensifier and video camera have been replaced with flat panel detectors (FPDs). FPDs have advantages over traditional systems such as higher spatial resolution, greater dynamic range, and improved contrast resolution. They also eliminate the need for periodic maintenance of image intensifiers and reduce radiation dose to patients and staff. WLs, DSAs, and LEDs are not direct replacements for image intensifier-based fluoroscopy systems.
