Systems and methods for matching and imaging tissue characteristics
First Claim
1. A method for imaging an electromechanical wave propagation through a tissue, comprising:
- acquiring tissue data for at least a first sector and a second sector of said tissue, said electromechanical wave propagating through said first and second sectors of said tissue;
estimating a characteristic of at least a portion of said first sector and a characteristic of at least a portion of said second sector from said acquired tissue data;
matching said estimated characteristic of said portion of said first sector with said estimated characteristic of said portion of said second sector;
determining a time delay between said matched characteristic of said portion of said first sector and said matched characteristic of said portion of said second sector; and
forming an image of said electromechanical wave propagating through said portion of said first sector and said portion of said second sector utilizing said determined time delay.

Abstract
Systems and methods for matching a characteristic of multiple sectors of a moving tissue to verify an overlap thereof are disclosed herein. In an exemplary method, tissue data for at least a first sector and a second sector of a moving tissue is acquired. A characteristic of at least a portion of the first and second sectors is estimated from the acquired tissue data, and the estimated characteristics are matched to verify whether a portion of the first sector overlaps with a portion of the second sector. Estimating can include estimating a displacement such as an axial displacement and/or lateral displacements. Estimating can further include estimating a strain, a velocity, a strain rate and/or a stiffness or equivalent.

12. A system for imaging an electromechanical wave propagation through a tissue, comprising:
-
a non-transitory computer readable medium storing program instructions; and a processor adapted to receive tissue data for at least a first sector and a second sector of said tissue, said electromechanical wave propagating through said first and second sectors of said tissue, wherein said processor is operatively connected to said non-transitory computer readable medium and configured to execute said stored program instructions, wherein said processor is further configured such that upon execution of said stored program instructions, said processor; estimates a characteristic of at least a portion of said first sector and a characteristic of at least a portion of said second sector from said acquired tissue data, matches said estimated characteristic of said portion of said first sector with said estimated characteristic of said portion of said second sector; determining a time delay between said matched characteristic of said portion of said first sector and said matched characteristic of said portion of said second sector; and forming an image of said electromechanical wave propagating through said portion of said first sector and said portion of said second sector utilizing said determined time delay. - View Dependent Claims (13, 14, 15)
