1. A method, comprising:
generating cardiac ultrasound images from ultrasound imaging data of a heart;
segmenting pericardium depicted in the cardiac ultrasound images and applying a pericardium mask to the pericardium segmented in the cardiac ultrasound images;
excluding the pericardium depicted in the cardiac ultrasound images by excluding the masked pericardium; and
calculating strain values of a myocardium region of interest in the cardiac ultrasound images while excluding the masked pericardium depicted in the cardiac ultrasound images.
