Question

Quizplus · Accepted Answer

MTF (Modulation Transfer Function) is a measure of how well an imaging system reproduces detail, including the sharpness and contrast of the image.

Answer: H
 Phosphorescence is the property of emitting light following exposure to light. It is used in some film-screen image receptor systems.

Answer: D
 Conversion efficiency refers to the ability of an imaging system to convert X-ray photons into visible light.

Answer: I
 Quantum mottle is a noise artifact in X-ray imaging due to insufficient radiation exposure or an inadequate number of photons reaching the image receptor. It can be reduced by increasing radiation exposure, but this also increases patient dose.

Answer: L
 lp/mm (lines per millimeter) is a measure of spatial resolution in imaging.
