A pre-swirl fin (PSF), duct (PSD) and wake-equalizing (WED) energy-saving devices (ESD) are designed for the Duisburg Test Case (DTC). To this aim, a simulation-based design optimization method, combining RANSE analyses (ship resistance) with BEM calculations (unsteady propeller performances) in simplified process realized through parametric description of ESD geometries, was employed. Fully re...

Introduction: Fast-spin echo (FSE) imaging is one of the most frequently used pulse sequences for brain imaging due to its scan time efficiency, good tissue contrast, and high effective resolution. Practical problems that occur are mostly due to patient motion, which leads to blurring and imaging ghosting (Fig. 1b). To make the acquisition robust to motion, the T2-w PROPELLER pulse sequence can...

The PROPELLER sequence is clinically used for T2 and DW imaging and can be motion corrected. Parallel imaging techniques have been used in axial PROPELLER imaging to effectively widen the blade, thus reducing motion artifacts and improving general image quality. However, parallel imaging is not suitable for all image orientations with all available coils (e.g. PROPELLER spine imaging). We propo...
