1. A system for determining plaque composition, the system comprising:
- an ultrasound system with a non-invasive probe for collecting ultrasound data including backscatter signals from a blood vessel;
signal analyzer logic for analyzing the ultrasound signal data and determining one or more signal properties from the backscatter signals of the blood vessel; and
correlation logic configured to associate the one or more signal properties to pre-determined signal properties of plaque components, and configured to identify components of the blood vessel based on the association.

Abstract
One embodiment of the present system and method is directed to the identification of tissues within a vascular object by analyzing ultrasound data collected from the vascular object by non-invasive scans. By identifying and characterizing types of tissue from ultrasound data, an assessment can be made about the health condition of a patient without an invasive procedure. Other applications of the present system will also be appreciated including identifying other types of tissues.

10. An article of manufacture embodied in a computer-readable medium for use in a processing system for analyzing ultrasound signal data, the article of manufacture comprising:
-
first processor executable instructions for causing a processor to receive ultrasound signal data of a scanned object collected from a non-invasive probe;
second processor executable instructions for causing a processor to determine signal properties of one or more regions of interest associated with the scanned object from the ultrasound signal data; and
third processor executable instructions for causing a processor to classify the one or more regions of interest as a component type based on a classification data structure pre-determined from measured associations between signal properties and one or more component types of an object similar to the scanned object. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of identifying one or more components of an object, the method comprising:
-
receiving backscatter signals from an ultrasonic probe scanning the object from a location external to the object;
determining one or more signal properties from the backscatter signals; and
identifying one of more components of the object by comparing the one or more signal properties to pre-determined combinations of signal properties that identify a component having a similar combination of signal properties. - View Dependent Claims (21, 22, 23, 24, 25)
