AI‐Enabled Imaging for Pathogen Detection Under Stress Conditions: A Systematic Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Advances in pathogen detection that incorporate artificial intelligence (AI) may capture microbial signals under challenging environmental conditions that traditional methods miss. This systematic review evaluates the application, performance, and methodological characteristics of AI‐enabled imaging for pathogen detection, including its impact

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets

Structural Dynamics, 2015
Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a ...

Comparing image quality of synchrotron and laboratory nano‐CT scans: a round robin study

Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 489-507, March 2026.
A multi‐facility round‐robin comparison of synchrotron‐ and laboratory‐based nano‐computed tomography using a standardized 3D phantom reveals superior resolution and acquisition speed at synchrotrons, while advanced laboratory systems achieve competitive image quality with extended scan times; phase contrast modalities further enhance structural ...

Compact lensless digital holography [PDF]

, 2018
Microscopy is of high interest for biology since it allows imaging features that are too small to be seen with naked eyes. However, cells are mostly transparent to visible and infrared light which makes it difficult to see with a traditional microscope ...

Lensless imaging with ultrabroadband light sources:Towards efficient table-top soft-X-ray microscopy

, 2012
We demonstrate high-resolution coherent lensless imaging using ultra-broadband light sources. We exploit Fourier-transform techniques to remove all spectral bandwidth limitations, paving the way for efficient soft-X-ray microscopy with high-harmonic ...

Material-resolved and thickness-sensitive lensless imaging using high-harmonic generation: From diffractive shear interferometry to ptychography [PDF]

EPJ Web of Conferences
Microscopy with table-top high-harmonic generation (HHG) sources enable high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-specific absorption edges available in this spectral range.

Adaptively coupled phase retrieval in multi‐peak Bragg coherent diffraction imaging

Journal of Applied Crystallography, Volume 59, Issue 1, Page 40-48, February 2026.
We present an adaptively coupled phase retrieval algorithm for multi‐peak Bragg coherent diffraction imaging. The technique uses the redundant information contained in separate Bragg peaks to detect and remove spurious signal.Recent advances in Bragg coherent diffraction imaging (BCDI) experimental techniques permit routine measurement of multiple ...
