Assignee:

General Electric Company - Niskayuna NY

International Classification:

H05G 1/64

US Classification:

378 989, 378 53

Abstract:

An energy discrimination radiography system includes at least one radiation source configured to alternately irradiate a component with radiation characterized by at least two energy spectra, where the component has a number of constituents. At least one radiation detector is configured to receive radiation passing through the component and a computer is operationally coupled to the detector. The computer is configured to receive data corresponding to each of the energy spectra for a scan of the component, process the data to generate a multi-energy data set, and decompose the multi-energy data set to generate material characterization images in substantially real time. A method for inspecting the component includes irradiating the component, receiving a data stream of energy discriminated data, processing the energy discriminated data, to generate a multi-energy data set, and decomposing the multi-energy data set, to generate material characterization images in substantially real time.

International Classification:

G01T 1/166

US Classification:

250370090

Abstract:

An imaging system for dynamically optimizing an image is provided. The imaging system includes a source of radiation, and a detector assembly configured to generate an image signal based on an incidence of radiation on a scintillator assembly. At least one or more properties of the generated image signal are determined from the incidence of radiation on the detector assembly. The one or more properties of the image signal may also be determined from one or more detector operational parameters. The imaging system also includes a detector adjustment circuitry that is configured to adjust the one or more detector operational parameters based on the generated image signal.

International Classification:

A61B 6/00
A61B 6/03

Abstract:

An imaging method includes executing a low-dose preparatory scan to an object by applying tube voltages and tube currents in an x-ray source, and generating a first image of the object corresponding to the low-dose preparatory scan. The method further includes generating image quality estimates and dose estimates view by view at least based on the first image. The method includes optimizing the tube voltages and the tube currents to generate optimal profiles for the tube voltage and the tube current. At least one of the optimal profiles for the tube voltage and the tube current is generated based on the image quality estimates and the dose estimates. The method includes executing an acquisition scan by applying the tube voltages and the tube currents based on the optimal profiles and generating a second image of the object corresponding to the acquisition scan. An imaging system is also provided.
