This paper presents a calibration and correction method for detector cell gain variations. To provide variable slice thickness capability in multislice volumetric scanners, while minimizing costs, it is necessary to combine the signals from several d

The principles and operations of 4-slice helical CT are discussed. The SSP, image noise and artifacts of a 4-slice scanner are measured by phantom scans and compared with theoretical predictions and the measurements of single-slice CT. The evaluation

We describe a one-dimensional x-ray-scattering model that includes discrete layer-thickness fluctuations and interfacial diffusion in the kinematical approximation. We demonstrate the use of the model in an analysis of the out-of-plane scattering int
