Fluoroscopy Lecture Notes

A series of flashcards covering key concepts and vocabulary from the fluoroscopy lecture notes.

Fluoroscopy

An imaging technique that shows a continuous x-ray image on a monitor.

Image Intensification

A process that converts an x-ray image into a brighter visible light image.

Brightness Gain

The ratio of the brightness of the output to the brightness of the input.

Automatic Brightness Control (ABC)

An electronic feedback system that maintains optimal image brightness during fluoroscopy.

Quantum Mottle

A grainy appearance of the image caused by insufficient exposure.

Digital Fluoroscopy

Uses digital imaging technology for fluoroscopic examinations, improving resolution and reducing dose.

Flux Gain

A measure of the conversion efficiency of the output screen in an image intensifier.

Minification Gain

The ratio of the input screen diameter to the output screen diameter, affecting brightness.

Resolution

The ability to distinguish fine details in an image.

Vignetting

The gradual dimming of an image towards its corners, affecting image quality.
