Assignee:

Computerzied Thermal Imaging, Inc. - Layton UT

International Classification:

G06K 900

US Classification:

382128, 128922, 2503161, 2503381, 356 51, 600306, 600310, 600475, 374 10, 702135

Abstract:

A system and method is disclosed for helping determine a condition of selected tissue of a patient based on a set of thermal images of the selected tissue acquired over a time period. The image set has image regions with corresponding characteristics indicative of a temperature condition of an associated part of the selected tissue, which had been subjected to a thermal challenge during part of the image acquisition time period. Feature values are determined based on the characteristics of selected image regions. A classifier is applied to the features to provide an indication of the condition of the selected tissue, such as indicating a likelihood of malignancy.

International Classification:

G01N 700

US Classification:

73 232

Abstract:

An integrated airway adapter capable of monitoring CO. sub. 2 concentration in real time, breath by breath using infrared absorption techniques and monitoring respiratory flow with differential pressure flowmeters under diverse inlet conditions through improved sensor configurations which minimize phase lag and dead space within the airway adapter.

Appl. No.:

14/308979

Inventors:

- Beltsville MD, US
David C. RICH - Stafford VA, US

International Classification:

G01S 7/52
G01S 15/02

Abstract:

An image sensor includes a source configured to output ultrasound, a probe for emitting the ultrasound onto a scan area, the probe being moveable relative to at least two scan locations of the scan area such that the ultrasound will be focused on each of the at least two scan locations as the probe is moved relative to the scan area to provide an array of scanned images, an ultrasonic, two-dimensional array receiver configured to receive ultrasound reflected from each of the at least two scan locations, and a processing unit configured to generate, for a first of the scan locations, a two-dimensional image of the first scan location based on an intensity of the reflected ultrasound from the first scan location, and to generate an aggregate two-dimensional image for the first scan location which integrates plural two-dimensional images generated using reflected ultrasound of the at least two scan locations.
