This dataset contains left ventricle endocardial contour data (and derived quantities) generated as part of a study to test the inter-user and inter-software repeatability of strain and volume measures of cardiac function. Seven users used two different software packages (ScanIP and OsiriX) to segment 30 short-axis MR images of a porcine heart, and repeated this twice. The same segmentation was also performed automatically using a third software, CVI42. Each instance of the data therefore contains the points that define the endocardial border for each attempt, as well as derived quantities such as circumferential strains and ;eft ventricular volume fractions. Finally, the specific data used to generate the plots, such as Bland-Altman plot, that appear in the paper are also presented.
