Exploring student perceptions of integrating mixed reality with cadaveric teaching in undergraduate neuroanatomy education: A qualitative study

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Mixed reality (MR) using head‐mounted displays provides three‐dimensional visualizations that have been suggested to enhance learning when used alongside conventional anatomy teaching in medical education. This study explored student perceptions of the integration of MR and traditional cadaveric learning, and their optimal delivery to support ...

Refractive Index–Correlated Pseudocoloring for Adaptive Color Fusion in Holotomographic Cytology

open access: yesCytometry Part A, EarlyView.
ABSTRACT Conventional bright‐field (BF) cytology of thyroid fine‐needle aspiration biopsy (FNAB) suffers from staining variability and limited subcellular contrast. Here, we present a refractive index–correlated pseudocoloring (RICP) framework that integrates quantitative refractive index (RI) maps obtained by holotomography (HT) with color BF images ...

Computational load reduction by avoiding the recalculation of angular redundancy in computer‐generated holograms

open access: yesETRI Journal, 2019
A fast hologram calculation approach is proposed to reduce computational load by avoiding the recalculation of redundancy information. In the proposed method, the hologram is divided into several sub‐holograms that record and reconstruct different views ...

Applications of computer-generated holograms in optical testing

open access: yes, 1980
Optical testing often requires a measurement of the phase difference between light from two different optical systems. One system is a master or reference system, and the other is a sample or test system.

Photothermal bubble: Dynamics, manipulation, and applications

open access: yesDroplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.
