Method of visualizing a sequence of ultrasound images, computer program product and ultrasound system

A method of visualizing a sequence of 3D ultrasound images, the method comprising:

• acquiring a sequence of 3D ultrasound images of an object in complex motion, the complex motion comprising motion components from a plurality of origins, wherein the sequence includes a first 3D ultrasound image acquired at a first point in time and a second 3D ultrasound image acquired at a second point in time, wherein each of the first and second 3D ultrasound images includes a plurality of regions of interest (ROIs) that divide the object into multiple segments;
• determining, from the first and second 3D ultrasound images, the complex motion of the object by determining relative motion of the respective segments in each of the plurality of ROIs in the first and second 3D ultrasound images;
• modelling a first subset of the motion components of the complex motion corresponding to a reference motion of the object between the first and second 3D ultrasound images;
• and
• comparing the complex motion of the object to the reference motion to provide a motion-decomposed visualization of the complex motion of the object by subtracting the reference motion from the complex motion and displaying the subtraction result to provide the motion-decomposed visualization of the complex motion.
