Of the choices below, which one will yield a radiographic image with the highest spatial resolution?
A)an image system with a MTF of 0.7
B)an image system with a MTF of 0.4
C)an image system with an average gradient of 2.0
D)an image system with an image density of 1.2

Question

Quizplus · Accepted Answer

The Modulation Transfer Function (MTF) is a measure of how accurately the system reproduces various spatial frequencies, with higher MTF indicating better spatial resolution. Therefore, an image system with an MTF of 0.7 would yield a better spatial resolution than one with an MTF of 0.4. The average gradient and image density do not directly relate to spatial resolution.
