Filed:

Jun 3, 2010

Appl. No.:

12/793210

Inventors:

Ming Zhang - Wayland MA, US
Omar Al-Kofahi - Woburn MA, US
Wamiq Ahmed - Woburn MA, US

Assignee:

American Science and Engineering, Inc. - Billerica MA

International Classification:

G01N 23/04

US Classification:

378 57, 378 62

Abstract:

Methods for a tangible image of an inspected object. An object is illuminated with at least two sources of penetrating radiation that generate respective pencil beams and define respective viewing points and view planes. Post-interaction penetrating radiation due to the respective sources is used to generate signals based on respective views of the inspected object, and thus derive information with respect to a dimension transverse to the first view plane based on the second signal. A tangible image of the inspected object is then displayed depicting information with respect at least to the first view plane and the transverse dimension.

International Classification:

G01N 23/201

US Classification:

378 86, 378 57, 378 87

Abstract:

A system and methods for characterizing regions within, or on, an inspected object, wherein a lower-Z scattering material and a higher-Z material may both lie along a common line of sight. The inspected object is scanned with penetrating radiation characterized by an energy distribution, and penetrating radiation scattered by the inspected object is detected in a manner that generates two detector signals that distinguish between materials of higher and lower effective atomic number under distinct sets of conditions with respect to the energy distribution of the penetrating radiation. An image is generated, based on a function of the two detector signals, as is a differential image, so as to allow distinction of higher-Z and lower-Z materials.

G06T 7/00

Abstract:

Determining a composite score includes deriving, based on an image set that includes at least one three-dimensional image of the synovial joint, first and second information. The first information indicates cumulative damage to the synovial joint. The second information indicates either one or both joint pain and loss of function of the synovial joint. The resulting composite score provides an objective measure of joint damage or an extent of joint disease.
