Advanced noise-optimized virtual monochromatic imaging for improving the contrast of dual-energy CT pulmonary angiography

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine
Background Pulmonary embolism (PE) is a serious condition requiring accurate imaging for timely diagnosis. While computed tomography pulmonary angiography (CTPA) is the standard tool, its quality may be limited by contrast timing or noise. Dual-energy CT

A comparison of the image quality between deep learning reconstruction algorithm and iDose4 using low dose abdominopelvic computed tomography for individuals with normal BMI

open access: yesSAGE Open Medicine
Objectives: Radiation exposure has been a cause of concern in computed tomography imaging. Reducing radiation dose increases the image noise which can be compensated by using reconstruction techniques.

Optimising sample preparation to enhance contrast-to-noise ratio in X-ray phase contrast tomography white matter (WM) imaging of the central nervous system

open access: yesFrontiers in Physics
The choice of fixative is critical in X-ray phase-contrast tomography (XPCT) because it affects tissue preservation, contrast enhancement and compatibility with other imaging techniques.

Artificial neural network for enhancing signal-to-noise ratio and contrast in photothermal optical coherence tomography

open access: yesScientific Reports
Optical coherence tomography (OCT) is a medical imaging method that generates micron-resolution 3D volumetric images of tissues in-vivo. Photothermal (PT)-OCT is a functional extension of OCT with the potential to provide depth-resolved molecular ...
