A system for scoring motion of a heart wall, the system comprising: an imaging system operable to acquire a first image of the heart wall at a first time and a second image of the heart wall at a second time; a processor configured to: identify a first set of contour data in the first image; identify a second set of contour data in the second image; in dependence on the first and second sets of contour data (234, 244), define at least one element (E i) representing a cardiac cyclic change in a section of the heart wall; analyse the or each element (E i) to generate two or more metrics; the system characterised in that the processor is further configured to: compare the two or more metrics generated for the or each element (E i) with a reference data model to score the motion of the corresponding section of the heart wall, the reference data model comprising a first principal component; wherein the scoring comprises calculating a score for the or each element (E i) in dependence on bivariate or multivariate analysis of the two or more metrics generated for that element (E i), the score representing a value of the two or more metrics on the first principal component of the reference data model. an imaging system operable to acquire a first image of the heart wall at a first time and a second image of the heart wall at a second time; a processor configured to: identify a first set of contour data in the first image; identify a second set of contour data in the second image; in dependence on the first and second sets of contour data (234, 244), define at least one element (E i) representing a cardiac cyclic change in a section of the heart wall; analyse the or each element (E i) to generate two or more metrics; the system characterised in that the processor is further configured to: compare the two or more metrics generated for the or each element (E i) with a reference data model to score the motion of the corresponding section of the heart wall, the reference data model comprising a first principal component; wherein the scoring comprises calculating a score for the or each element (E i) in dependence on bivariate or multivariate analysis of the two or more metrics generated for that element (E i), the score representing a value of the two or more metrics on the first principal component of the reference data model. identify a first set of contour data in the first image; identify a second set of contour data in the second image; in dependence on the first and second sets of contour data (234, 244), define at least one element (E i) representing a cardiac cyclic change in a section of the heart wall; analyse the or each element (E i) to generate two or more metrics; compare the two or more metrics generated for the or each element (E i) with a reference data model to score the motion of the corresponding section of the heart wall, the reference data model comprising a first principal component; wherein the scoring comprises calculating a score for the or each element (E i) in dependence on bivariate or multivariate analysis of the two or more metrics generated for that element (E i), the score representing a value of the two or more metrics on the first principal component of the reference data model.
