Modulation transfer function measurement of CT images by use of a circular edge method with a logistic curve-fitting technique

We propose a method for measuring the modulation transfer function (MTF) of a computed tomography (CT) system by use of a circular edge method with a logistic curve-fitting technique. An American College of Radiology (ACR) phantom was scanned by a Philips Brilliance system, and axial images were rec...
