US Patent:

20230011644, Jan 12, 2023

Filed:

May 24, 2022

Appl. No.:

17/664855

Inventors:

- Newport Beach CA, US
Ying Zhao - Newport Beach CA, US

International Classification:

A61B 6/00
A61B 6/03
A61B 6/02

Abstract:

An x-ray system and method can improve speed of imaging and/or reduce radiation dosage compared to conventional imaging technique, such as CT. The system can identify a volume of interest within a subject. The system can include scatter removal algorithms and/or a beam selection device. Material decomposition of the imaged subject can be based on the dual energy decomposition method which can be iterative to solve the energy response function equation system.

International Classification:

A61B 6/00
A61B 6/06

Abstract:

An x-ray apparatus and method can improve x-ray imaging in a variety of ways. For example, the improve x-ray apparatus can reduce scatter from x-ray images acquired by two-dimensional detectors. An improved 2D x-ray apparatus can provide 3D imaging for medical and/or industrial applications. An improved 2D x-ray apparatus and method can produce separate material imaging, and composition analysis for characterization and correlation of image, densitometry, and composition information of individual component or individual material within a single subject. Non-rotational 3D microscopy, combining 2D or 3D full field x-ray imaging and high resolution 2D or 3D x-ray microscopy or spectral absorptiometry and spectroscopy can achieve a higher resolution and wider field of view in x-ray imaging and quantitative analysis in 3D and real time. The x-ray apparatus can improve tracking and/or surgical guidance in time and/or space.

A61B 6/00

Abstract:

An x-ray tomography system which can generate a qualitative 3D image of a region of interest using a an x-ray source, the x-ray source configured to emit x-ray radiation at the region of interest. The x-ray radiation or the x-ray source or the relative position of the x ray source configured to be moved in a two dimensional plane. An x-ray detector including a plurality of detector elements arranged in a two dimensional plane opposite the x-ray source, the x-ray detector configured to detect x-ray radiation after attenuation by the subject and provide an indication of the detected x-rays. And a processor configured to receive the indication of the detected x-rays and resolve the detected x-ray radiation into a three dimensional image. The three dimensional image is qualitative in nature.
