PURPOSE To demonstrate accelerated imaging with both artifact reduction and different contrast mechanisms near metallic implants. MATERIALS AND METHODS Slice-encoding for metal artifact correction (SEMAC) is a modified spin echo sequence that uses view-angle tilting and slice-direction phase encoding to correct both in-plane and through-plane artifacts. Standard spin echo trains and short-TI ...

The purpose of this study was to evaluate different approaches for scatter artifact reduction in the field of dimensional computed tomography (CT). The methods we investigated can be subdivided into one software-based method and three hardware-based methods. The software-based method uses a Monte Carlo scatter simulation to estimate scatter intensities for an initial model of the geometrical an...

Different programming languages can be involved in the implementation of a single software application. In these software applications, source code of one programming language interacts with code of a different language. By refactoring an artifact of one programming language, the interaction of this artifact with an artifact written in another programming language may break. We present a study ...
