First application experiments with the Stockholm compact soft x-ray microscope [PDF]

open access: yes, 2022
Most soft x-ray microscopes operating in the water window (λ = 2.3 − 4.4 nm) rely on synchrotron radiation sources. In the future we believe scientists will use soft x-ray microscopes as one imaging tool among others in their own laboratory.

Dose-efficient assessment of trabecular microstructure using ultra-high-resolution photon-counting CT

open access: yesZeitschrift für Medizinische Physik, 2022
Photon-counting (PC) detectors for clinical computed tomography (CT) may offer improved imaging capabilities compared to conventional energy-integrating (EI) detectors, e.g. superior spatial resolution and detective efficiency.

Karyotyping human chromosomes by optical and X-ray ptychography methods [PDF]

open access: yes, 2014
Sorting and identifying chromosomes, a process known as karyotyping, is widely used to detect changes in chromosome shapes and gene positions. In a karyotype the chromosomes are identified by their size and therefore this process can be performed by ...

Registration and tracking to integrate X-ray and MR images in an XMR facility [PDF]

open access: yes, 2003
We describe a registration and tracking technique to integrate cardiac X-ray images and cardiac magnetic resonance (MR) images acquired from a combined X-ray and MR interventional suite (XMR).

Mitigation of DMM-induced stripe patterns in synchrotron X-ray radiography through dynamic tilting

open access: yesJournal of Synchrotron Radiation
In synchrotron X-ray radiography, achieving high image resolution and an optimal signal-to-noise ratio (SNR) is crucial for the subsequent accurate image analysis.

3D ultrastructural organization of whole Chlamydomonas reinhardtii cells studied by nanoscale soft x-ray tomography [PDF]

open access: yes, 2012
The complex architecture of their structural elements and compartments is a hallmark of eukaryotic cells. The creation of high resolution models of whole cells has been limited by the relatively low resolution of conventional light microscopes and the ...

Combined scanning small-angle X-ray scattering and holography probes multiple length scales in cell nuclei [PDF]

open access: yes, 2022
X‐rays are emerging as a complementary probe to visible‐light photons and electrons for imaging biological cells. By exploiting their small wavelength and high penetration depth, it is possible to image whole, intact cells and resolve subcellular ...

Generalized noise power spectrum modeling for robotic CT with arbitrary scan paths

open access: yesNuclear Engineering and Technology
The noise characteristics of cone-beam computed tomography (CBCT) systems with flat-panel detectors significantly affect the image quality and may limit defect detectability in industrial imaging applications.
