Filed:

Dec 29, 2000

Appl. No.:

09/751074

Inventors:

Guy M. Besson - Broomfield CO

Assignee:

GE Medical Systems Global Technology Company, LLC - Waukesha WI

International Classification:

A61B 603

US Classification:

378 15, 378901

Abstract:

One aspect of the present invention is a CT imaging method. An object is scanned at a selected helical pitch to acquire a set of attenuation measurement. For each angle of a fan beam of radiation, a direct and a conjugate set of attenuation measurements are identified that each include at least two measurements closest to a plane of reconstruction. Measurements are arranged in pairs, including a short pair and a long pair, using direct and conjugate measurements. Direct measurements are weighted in accordance with their distance from the plane of reconstruction. Direct measurements of the short and long pairs are blended according to a blending function that weights the short pair contribution to zero at a point at which the selected direct pair and the selected conjugate pair have a same z-axis location. The weighted and blended data is used to reconstruct an image of the object.

Morgan W. Nields - Englewood CO, US

Assignee:

Fischer Imaging Corporation - Denver CO

International Classification:

A61B 800

US Classification:

600437

Abstract:

An integrated x-ray and ultrasound medical imaging system is provided, wherein a radiation detection means and ultrasound transducer may be disposed for scanning movement for image acquisition along either the same or substantially coincidental paths. The radiation detection means and ultrasound transducer may be advantageously located on the same side of the imaged body portion. The x-ray and ultrasound imaging operations may be sequential, partially overlapping, or synchronous. By virtue of the noted arrangement, increased accuracy and medical efficiencies can be realized.

Abstract:

Disclosed is a mammographic imaging system and tools for processing mammographic images to enhance image acquisition and review workflow. The systems and tools enable rapid access to digital image information providing for improved workflow management and identification of images, upon initial review. The system and tools also allow for background processing of image information to reduce workflow delay. Specifically, digital images are processed in the background, i. e. , they are automatically processed, free from specific task-orientated direction by a user, using resources that are not otherwise occupied addressing user-directed tasks. Background processing that may be supported includes preprocessing and interim processing. Preprocessing refers to processing of an image that occurs prior to initial review of that image by a physician. Interim processing refers to background processing that occurs during a review session, e. g.

Appl. No.:

10/876996

Inventors:

Guy M. Besson - Broomfield CO, US

International Classification:

A61B006/03

US Classification:

378 5, 378 16, 378901

Abstract:

A multispectral X-ray imaging system uses a wideband source and filtration assembly to select for M sets of spectral data. Spectral characteristics may be dynamically adjusted in synchrony with scan excursions where an X-ray source, detector array, or body may be moved relative to one another in acquiring T sets of measurement data. The system may be used in projection imaging and/or CT imaging. Processed image data, such as a CT reconstructed image, may be decomposed onto basis functions for analytical processing of multispectral image data to facilitate computer assisted diagnostics. The system may perform this diagnostic function in medical applications and/or security applications.

Filed:

Apr 11, 2003

Appl. No.:

Inventors:

Guy M. Besson - Broomfield CO, US

Assignee:

Fischer Imaging Corporation - Denver CO

International Classification:

A61B 6/00

US Classification:

378 37, 378 87, 378 984

Abstract:

Scatter effects are reduced in a radiographic imaging device, such as a digital slot scan mammographic imaging device, by reducing detected scatter and processing detector information to compensate for scatter effects. Spatial intensity profile information together with other imaging signal and patient dependent parameters can be used in image processing to estimate and compensate for various scatter effects including single and multiple scatters and Compton and Rayleigh scatter.
