Abstract

A method for automatically identifying and localizing anatomical regions of a left ventricle of a heart using a segment model, the method including receiving a volumetric MR image series of one or more time-points in a heart cycle with associated myocardial boundaries, representing the heart, performing a long-axis partitioning on each image of the volumetric image series, performing a short-axis partitioning volumetric image series, generating a polar map, wherein each image of the volumetric image series is mapped to a location on the polar map, wherein the location is characterized using the long-axis partitioning and the short-axis partitioning, and generating a mapping from the polar map to a voxel in an associated image of the volumetric image series representing an anatomical location.

First claim

1 - 6 . (canceled)

7 . A computer program product for automatically identifying and localizing anatomical regions of a left ventricle of a heart using a segment model, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:
receiving a volumetric image series of one or more time-points in a heart cycle with associated myocardial boundaries, representing the heart; performing a long-axis partitioning on each image of the volumetric image series; performing a short-axis partitioning volumetric image series; generating a polar map, wherein each image of the volumetric image series is mapped to a location on the polar map, wherein the location is characterized using the long-axis partitioning and the short-axis partitioning; and generating a mapping from the polar map to a voxel in an associated image of the volumetric image series representing an anatomical location.

8 . The computer program product of claim 7 , further comprising automatically generating the polar map.

9 . The computer program product of claim 7 , wherein a functional measurement is represented in the polar map by a color range and the anatomical location is directly related to a specific segment of the polar map.

10 . The computer program product of claim 7 , wherein the polar map displays regional functional parameters.

11 . The computer program product of claim 7 , the polar map has a 1-to-1 linkage to a corresponding image of the volumetric image series.

12 . The computer program product of claim 11 , further comprising receiving an indication of a location on the polar map and outputting a corresponding tissue or its functional parameters.
