Appl. No.:

12/436329

Inventors:

Justin S. Baba - Knoxville TN, US
Brian S. Letzen - Coral Springs FL, US

Assignee:

UT-Battelle, LLC - Oak Ridge TN

International Classification:

G01N 21/47
G01B 9/02

US Classification:

356446, 356451

Abstract:

An optical sample is mounted on a spatial-acquisition apparatus that is placed in or on an enclosure. An incident beam is irradiated on a surface of the sample and the specular reflection is allowed to escape from the enclosure through an opening. The spatial-acquisition apparatus is provided with a light-occluding slider that moves in front of the sample to block portions of diffuse scattering from the sample. As the light-occluding slider moves across the front of the sample, diffuse light scattered into the area of the backside of the light-occluding slider is absorbed by back side surface of the light-occluding slider. By measuring a baseline diffuse reflectance without a light-occluding slider and subtracting measured diffuse reflectance with a light-occluding slider therefrom, diffuse reflectance for the area blocked by the light-occluding slider can be calculated.

International Classification:

A61B005/00

US Classification:

600/318000

Abstract:

There are many inventions described and illustrated herein. In one aspect, the present invention is a system and technique for non-invasively measuring, monitoring, inspecting, characterizing, determining and/or evaluating the blood glucose level in the aqueous humor of the eye of a patient (for example, a diabetic). In one embodiment, the present invention employs a plurality of wavelengths of light (for example, more than three) to measure, monitor, characterize, determine and/or evaluate the blood glucose level or concentration of a patient. The plurality of wavelengths of light may be directed into the aqueous humor of the eye and the reflected light (i.e., the light reflected by the eye) is detected and analyzed to provide information which is representative of the blood glucose level or concentration of the patient.

International Classification:

A61B 5/055

US Classification:

382131, 600410

Abstract:

A method and related system for generating motion corrected tomographic images includes the steps of illuminating a region of interest (ROI) to be imaged being part of an unrestrained live subject and having at least three spaced apart optical markers thereon. At least one camera is used to obtain images of the markers. Motion data comprising 3D position and orientation of the markers relative to an initial reference position is then calculated. The at least three spaced apart optical markers and the at least one camera are sufficient in quantity and position to avoid multiple epipolar solutions. Motion corrected tomographic data obtained from the ROI using the motion data is then obtained, where motion corrected tomographic images obtained therefrom.

Abstract:

Systems and methods for generating motion corrected tomographic images are provided. A method includes obtaining first images of a region of interest (ROI) to be imaged and associated with a first time, where the first images are associated with different positions and orientations with respect to the ROI. The method also includes defining an active region in the each of the first images and selecting intrinsic features in each of the first images based on the active region. Second, identifying a portion of the intrinsic features temporally and spatially matching intrinsic features in corresponding ones of second images of the ROI associated with a second time prior to the first time and computing three-dimensional (3D) coordinates for the portion of the intrinsic features. Finally, the method includes computing a relative pose for the first images based on the 3D coordinates.
