Quizplus · Accepted Answer

Increasing the exposure technique (which generally means increasing the amount of radiation used) can reduce the appearance of noise in a digital image by improving the signal-to-noise ratio. This is because a higher dose increases the signal relative to the inherent electronic system noise and quantum mottle noise. Decreasing exposure intensity or turning off electronic devices does not directly improve the noise related to the image quality in this context.
