Three-dimensional imaging and scanning: Current and future applications for pathology

Journal of Pathology Informatics, 2017
Imaging is vital for the assessment of physiologic and phenotypic details. In the past, biomedical imaging was heavily reliant on analog, low-throughput methods, which would produce two-dimensional images.

Conformal acoustic holographic lenses for wavefront control via geometry-encoded design

Materials & Design
We present a conformal acoustic holographic lens as a functional material system that integrates geometric architecture, acoustic response, and fabrication for subject-specific wave manipulation. Transcranial focused ultrasound (tFUS) enables noninvasive

Image registration algorithm for molecular tagging velocimetry applied to unsteady flow in Hele-Shaw cell [PDF]

, 2013
In order to develop velocimetry methods for confined geometries, we propose to combine image registration and volumetric reconstruction from a monocular video of the draining of a Hele-Shaw cell filled with water.

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 ...

The reconstruction of digital holograms on a computational grid [PDF]

, 2006
Digital holography is greatly extending the range ofholography's applications and moving it from the lab into the field: a single CCD or other solid-state sensor can capture any number of holograms while numerical reconstruction within a computer ...
