The phase-contrast radiography is an edge-enhancement technique which allows to visualize objects providing very low contrast with the conventional absorption radiography technique. The image formation in this case is based on the phase variations transformed to intensity variations in a beam with a

An analysis of the effect of respiratory function on MR flow measures of the internal jugular vein (IJV) is presented. A novel 2D radial acquisition and reconstruction method allows for retrospective gating to both the cardiac and respiratory cycle. In-vivo scans of human volunteers verify the effic
To study the dependence of post-ablation scar visibility in late gadolinium enhancement (LGE) images of left arial wall on time interval after contrast agent injection
This paper introduces a newly conceived formalism for clinical in-line phase-contrast X-ray imaging. The new formalism applies not only to ideal ''thin'' objects analyzed in previous studies, but also applies to the real-world tissues used in actual clinical practice. Moreover we have identified the
## Abstract The soβcalled βKety modelβ is a twoβcompartment pharmacokinetic model describing tumor perfusion kinetics. Its parameters, the transendothelial transfer constant (__K__^__trans__^), extravascular extracellular volume fraction (Ο ~__e__~), and microvascular plasma volume fraction (Ο ~__p__
