Hemodynamics in a giant intracranial aneurysm characterized by in vitro 4D flow MRI. [PDF]

PLoS ONE, 2018
Experimental and computational data suggest that hemodynamics play a critical role in the development, growth, and rupture of cerebral aneurysms. The flow structure, especially in aneurysms with a large sac, is highly complex and three-dimensional ...

Automatic Reconstruction of 3D Building Models from ALS Point Clouds Based on Façade Geometry

ISPRS International Journal of Geo-Information
Three-dimensional (3D) building models are essential for urban planning, spatial analysis, and virtual simulations. However, most reconstruction methods based on Airborne LiDAR Scanning (ALS) rely primarily on rooftop information, often resulting in ...

Analytical evaluation of intact human tissues using mid-frequency scanning acoustic microscopy at the mesoscopic scale

Journal of Analytical Science and Technology
Conventional histological examination requires irreversible sectioning, consuming tissue and precluding three-dimensional analysis. This limitation is particularly problematic for archival specimens and forensic investigations.
