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.
Claims25
A method for matching a characteristic of two or more sectors of a moving tissue to verify whether any portions thereof overlap, comprising:
- acquiring tissue data for at least a first sector and a second sector of said moving tissue;
- estimating, using a processing arrangement, 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;
- and
- matching, using a processing arrangement, said estimated characteristic of said portion of said first sector with said estimated characteristic of said portion of said second sector, to verify whether said portion of said first sector overlaps with said portion of said second sector;
- and
- 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.
A system for matching a characteristic of two or more sectors of a moving tissue to verify whether any portions thereof overlap, comprising:
- a 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 moving tissue, wherein said processor is operatively connected to said 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, and
- matches said estimated characteristic of said portion of said first sector with said estimated characteristic of said portion of said second sector, to verify whether said portion of said first sector overlaps with said portion of said second sector, and wherein said processor is further configured to determine 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.
