Paper Abstract

The modulation transfer function was determined on the VolumeScope, a prototype X-ray Compton scatter tomographic scanner. The linear spread function of the device was measured independently along each coordinate axis with a 0.3 mm aluminum foil slightly angled with respect to the voxel grid. A technique of the presampled MTF generation was used to increase a sampling frequency of the data and reduce a statistical noise. The LSFs and MTFs along three coordinate axes are presented. The FWHMs of the LSF peaks are 2.50, 2.3 1 and 3.72 mm along the axes X, Y and Z respectively. The MTF cutoff frequencies are 0.45,0.50 and 0.35 cycle/mmrespectively.
