Impact of ROI Size on the Accuracy of Noise Measurement in CT on Computational and ACR Phantoms

Background: The effect of region of interest (ROI) size variation on producing accurate noise levels is not yet studied. Objective: This study aimed to evaluate the influence of ROI sizes on the accuracy of noise measurement in computed tomography (CT) by using images of a computational and American...
