PURPOSE A motion compensation method that is aimed at correcting motion artifacts of cardiac valves is proposed. The primary focus is the aortic valve. METHODS The method is based around partial angle reconstructions and a cost function including the

PURPOSE During a typical cardiac short scan, the heart can move several millimeters. As a result, the corresponding CT reconstructions may be corrupted by motion artifacts. Especially the assessment of small structures, such as the coronary arteries,

In the contemporary sociology of religion that focuses on the study of Orthodox religiosity, especially in Russia and partly in Serbia, there are different theoretical and methodological approaches to assessing the criteria of orthodox religiosity in

Purpose Optimization of the AIR–algorithm for improved convergence and performance. Methods The AIR method is an iterative algorithm for CT image reconstruction. As a result of its linearity with respect to the basis images, the AIR algorithm posse

The reconstruction of CT images with low noise and highest spatial resolution is a challenging task. Usually, a trade-off between at least these two demands has to be found or several reconstructions with mutually exclusive properties, i.e. either lo

Edge–preserving adaptive filtering within CT image reconstruction is a powerful method to reduce image noise and hence to reduce patient dose. However, highly sophisticated adaptive filters typically comprise many parameters which must be adjusted
