In imaging applications, because contrast resolution (the ability to resolve small differences in tissue contrast)is mandatory for diagnostic interpretation, ____ is important.

Question

Quizplus · Accepted Answer

High SNR (signal-to-noise ratio) is important in imaging applications because it improves contrast resolution, which is necessary for accurate diagnostic interpretation. Low SNR would result in a noisier image, making it more difficult to distinguish small differences in tissue contrast. DQE (detective quantum efficiency) is a measure of how efficiently a detector converts incoming radiation into a usable signal, and while it is important for overall image quality, it does not directly impact contrast resolution. Therefore, options A and D can be eliminated. Option B, high DQE, is beneficial but not as essential as high SNR for achieving good contrast resolution.
