ABSTRACT:
In one embodiment, at least one visual characteristic from a selected image is used to automatically select an ultrasound image from a set of images from a plurality of heart cycles. In another embodiment, motion correction is performed on ultrasound images that are automatically selected from a plurality of ultrasound images associated with the same phase of the heart cycle. In yet another embodiment, ultrasound images are automatically selected from a set of images based on a time interval that is within a tolerance range from a reference phase of the heart cycle. In another embodiment, a stored user-preference of a phase of the heart cycle is used to automatically select an ultrasound image from a set of images. In yet another embodiment, a user-defined region of interest is placed on an ultrasound image associated with a selected phase of a heart cycle.
