Clinical Applications of 3D Specimen Scanning and Margin Mapping in Musculoskeletal Oncology: A 36 Patient Case Series

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background Text‐based pathology reports inadequately communicate complex three‐dimensional (3D) relationships in musculoskeletal oncology, potentially contributing to errors in re‐resection and adjuvant treatment planning. While our prior 7‐case pilot study established technical feasibility, the scalability of this workflow and its utility as ...

Extended Depth-of-Field and 3D Information Extraction in Digital Holographic Microscopy

open access: yes, 2009
A comparison of algorithms for depth-of-field extension in the particular field of digital holographic microscopy is presented. Using the reconstruction properties of holography, a simple 3D reconstruction method from a single hologram is deducted ...

A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues

open access: yesLaser &Photonics Reviews, EarlyView.
The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

Recent Progress and Perspectives in Digital Holographic Microscopy

open access: yes, 2007
Recent developments in Digital Holographic Microscopy (DHM) have permitted to achieve imaging accuracies and resolutions down to the nano-range. This result could be obtained by careful control of all parameters involved in the wavefront reconstruction ...

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Digital holographic microscopy in human sperm imaging [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2011
The aim of this study was to use digital holographic microscopy (DHM) in human sperm imaging and compare quantitative phase contrast of sperm heads in normozoospermia (NZ) and oligoasthenozoospermia (OAT).DHM spermatozoa imaging and repeated quantitative phase shift evaluation were used. Five NZ and 5 OAT samples were examined.

Improving ARTs: Microfluidics as a Tool for Sperm Selection

open access: yesAndrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Ultrasound Mediated Cellular Deflection Results in Cellular Depolarization

open access: yesAdvanced Science, 2022
Ultrasound has been used to manipulate cells in both humans and animal models. While intramembrane cavitation and lipid clustering have been suggested as likely mechanisms, they lack experimental evidence. Here, high‐speed digital holographic microscopy (
