Journal ArticleDOI
Autofocusing in digital holographic phase contrast microscopy on pure phase objects for live cell imaging
TL;DR: Results from investigations of an engineered surface and human pancreas tumor cells demonstrate the applicability of Fourier-weighting- and gradient-operator-based methods for robust and reliable automated subsequent numerical digital holographic focusing.
Journal ArticleDOI
Automated three-dimensional tracking of living cells by digital holographic microscopy
Patrik Langehanenberg,Lyubomira Ivanova,Ingolf Bernhardt,Steffi Ketelhut,Angelika Vollmer,Dieter Dirksen,Georgi K. Georgiev,Gert von Bally,Björn Kemper +8 more
TL;DR: Results from investigations on sedimenting red blood cells and HT-1080 fibrosarcoma cells in a collagen tissue model demonstrate that DHM enables marker-free automated quantitative dynamic 3-D cell tracking without mechanical focus adjustment.
Journal ArticleDOI
The influence of maxillary central incisor position in complete dentures on /s/ sound production.
Christoph Runte,Michael Lawerino,Dieter Dirksen,Friedhelm Bollmann,Antoinette Lamprecht-Dinnesen,Eberhard Seifert,Eberhard Seifert +6 more
TL;DR: Immediate phonetic adaptation of prosthetic restorations in the maxillary incisor region can be achieved only if the original position of the natural teeth is transferred to the denture.
Journal ArticleDOI
2D and 3D analysis methods of facial asymmetry in comparison.
Philipp Berssenbrügge,Nina Franka Berlin,Günther Kebeck,Christoph Runte,Susanne Jung,Johannes Kleinheinz,Dieter Dirksen +6 more
TL;DR: Three selected 2D analysis methods and one 3D analysis method are compared and a mirror plane, which meets best the partial symmetry of the face regarding the median sagittal plane, and a 3D asymmetry index quantifying the overall facial asymmetry characteristics are presented.
Journal ArticleDOI
Quantitative phase imaging for cell culture quality control.
TL;DR: The results show that QPI enables label‐free imaging cytometry, which provides novel complementary integral biophysical data sets for sophisticated quantification of cell culture quality with minimized sample preparation.
