According to one embodiment, a moving object contour extraction apparatus includes a contour acquisition unit and a contour correction unit. The contour acquisition unit is configured to acquire a contour of a moving object in each image slice. The contour correction unit is configured to correct the contours of the moving object in image slices of at least one image slice time series based on motion trend information of the moving object in each of a plurality of image slice time series.

Moving object contour extraction apparatus, left ventricle image segmentation apparatus, moving object contour extraction method and left ventricle image segmentation method

A moving object contour tracking apparatus includes a contour tracking section for performing, by taking an initial contour of the moving object in a predetermined image slice as a starting contour, contour tracking in a first time direction to acquire a first contour of the moving object and contour tracking in a second time direction to acquire a second contour of the moving object in each image slice; a contour comparison section for calculating, in the predetermined image slice, a similarity between the first contour and the initial contour and a similarity between the second contour and the initial contour; and a contour correction section for taking the contours in the image slices that are acquired in a contour tracking direction corresponding to the greater one of the two similarities as the contours of the moving object in the respective image slices.
