The Application of Telemedicine in Surgery

Med Research, EarlyView.
This figure provides an overview of the content presented in this article. Telemedicine is integrated throughout the entire surgical workflow, with distinct applications across the preoperative, intraoperative, and postoperative phases. These applications are enabled by a suite of supporting technologies, while the associated implementation challenges ...

Full‐field X‐ray fluorescence imaging using a Fresnel zone plate as a coded aperture: optimized reconstruction algorithm and first trial of hyperspectral XANES mapping

Journal of Synchrotron Radiation, EarlyView.
The full‐field X‐ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full‐field and fluorescence modes, hyperspectral XANES mapping.This study ...

Theoretical Study of a Surface Collinear Holographic Memory

Photonics, 2019
Holographic memory is currently attracting attention as a data storage system capable of achieving a data transfer rate of about 105~106 times that of an optical disc such as Blu-ray disc. In conventional holographic memory, data is generally recorded by

Extended Reality in Endodontics: A Review of Current Applications and Future Potential

International Endodontic Journal, EarlyView.
ABSTRACT Background Extended reality (XR) technologies, encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), are increasingly used in endodontic education and practice. A gap exists regarding understanding of XR's applications and limitations among endodontic educators and practitioners.

Distortion Compensation of Reconstructed Hologram Image in Digital Holographic Display Based on Viewing Window

ETRI Journal, 2017
A holographic display based on a viewing window enables the converging of a reconstruction wave into a viewing window by means of an optical system. Accordingly, a user can observe a reconstructed hologram image, even with a small diffraction angle.

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...
