Electronic Fringe Scanning for the Improvement of Medical Imaging Technology
This technology includes an electronic method for fringe scanning in grating-based phase-contrast imaging, which enhances x-ray phase-contrast imaging. Traditional methods use high-density gratings and require fine grating fringes, finer than the detector's resolution, necessitating fringe scanning to obtain phase-contrast information. This process...

Multilayer X-Ray Transmission Grating Array for Phase-Contrast Imaging and Tomography
Classical X-ray Computed Tomography (CT) and radiography are based on X-ray absorption and cannot show soft tissue structures as well as Magnetic Resonance Imaging (MRI). Detecting the phase delay/advance of X-rays that travel through the body could enhance soft tissue contrast 10 - 100 times. Submicron-period X-ray transmission gratings for medical...

Fluorescent Nanodiamonds as Fiducial Markers for Microscopy
The invention relates to fluorescent nanodiamonds (FNDs) and their uses as fiducial markers for microscopy. FNDs are bright fluorescent probes that do not blink or bleach and have broad fluorescence excitation and emission peaks. The fluorescence intensity can be readily controlled by the size of the FND, the number of fluorescent centers produced...

Mapping Internal and Bulk Motion of an Object with Phase Labeling in Magnetic Resonance Imaging
Current MRI methods for tracking the motion of an object over a relatively long period of time requires the use of precisely defined grid points that may be inexact because of limited image resolution or the size of the element being tracked. Phase contrast velocity mapping generally provides high spatial resolution and simple data processing. However,...
