1. A quantitative analysis method for cardiac motion, comprising:
transmitting an ultrasonic wave to a target heart;
receiving an ultrasonic echo returned from the target heart;
determining an ultrasound image of the target heart according to the ultrasonic echo;
obtaining a region of interest in the ultrasound image;
performing motion tracking on the region of interest to obtain a torsion parameter of the target heart and a reliability of the torsion parameter, wherein the target heart is divided into multiple preset segments and the torsion parameter comprises rotation parameters of the multiple preset segments; and
displaying the rotation parameters of the multiple preset segments and reliabilities of the rotation parameters of the multiple preset segments.
