Researchers in Prof. Lei Xing's laboratory have developed a radioluminescent platform to combine molecular and X-ray imaging using standard X-ray equipment coupled with a photodetector.
Stanford researchers have invented a decoder for multiplexed readouts of imaging arrays that optimizes the signal-to-noise ratio (SNR) of the decoded detector pixel signals.
A volumetric computed tomography method includes translating a discrete element x-ray source and detector relative to the patient or object in a z-direction parallel to the axis of rotation.
Researchers in Prof. Lambertus Hesselink's laboratory have developed a compact, sensitive X-ray differential phase contrast (DPC) imaging system that improves field of view, increases fringe visibility and shortens imaging times.
Researchers in the Molecular Imaging Instrumentation Laboratory at Stanford University have developed methods to improve the image quality of tomographic image reconstruction, including positron emission tomography (PET).
Researchers at Stanford have developed a dual modality imaging probe to provide improved atherosclerosis detection and evaluation. Atherosclerosis is a disease in which plaque builds up inside arteries.
Researchers at Stanford University have developed a system for improved scatter correction in CT scans by simultaneously collecting image projection data and scatter data in a single scan.
Stanford researchers have developed a novel tomographic technique, cathodoluminescence (CL) spectroscopic tomography, to probe optical properties in 3D with nanometer-scale spatial and spectral resolution.
Disclosed is x-ray cone beam scan data reconstruction of an imaged object with a reconstruction algorithm using shift invariant filtering and backprojection with the maximum tomographic capability of a circular scan larger than p plus cone angle, when CB data is not truncated
Stanford researchers have developed a system and method to increase sampling in x-ray and CT images by deflecting the focal spot of an x-ray tube. This invention achieves focal spot z-wobble by shaping the rotating anode.
To determine the phase and magnitude of the complex electric field of
weak ultra-short pulses we propose to use a dummy strong pulse time
delayed relative to the weak pulse that needs to be characterized. This
Scatter radiation in an x-ray imaging system including an x-ray source and an x-ray detector is separated by using amplitude modulation to translate the spatial frequency of a detected x-ray beam to a higher frequency and provide separation from low frequency scatter signal.
The present invention provides a volumetric computed tomography (VCT) system capable of producing data for reconstructing an entire three-dimensional (3D) image of a subject during a single rotation without suffering from cone beam artifacts.
