A Stanford researcher has developed two advanced approaches for the positron sensitive high-energy photon sensor technology for Positron Emission Tomography (PET).
This invention, the “Charge Cloud Tracker” is a fast, low-cost, strip geometry x-ray detector that is predicted to provide limiting resolution on the order of 5 microns, with very high x-ray detection efficiency.
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.
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.
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.
Reduced source spacing for multi-source, multi-detector X-ray imaging systems is provided by allowing channels within an X-ray collimator to intersect within the body of the collimator.
A method for imaging an object in a computed tomography (CT) system with a plurality of sources comprising a first source and a second source, wherein the plurality of sources together with a detector array are mounted on a rotatable gantry, and wherein an intensity of the sec
