Abstract
Disclosed are a method for playing a CEUS movie file, an ultrasound movie file, and ultrasound apparatus. The method comprises: receiving a playing instruction for the movie file which is a dynamic data of generated by ultrasound echoes returned from a target tissue to which ultrasound waves are transmitted by a probe of an ultrasound apparatus; determining an imaging frame rate of the ultrasound images; determining a playback frame rate of the movie file according to the imaging frame rate negatively correlated with the playback frame rate; and playing the movie file with the playback frame rate. By using the playback frame rate which is negatively correlated with the imaging frame rate to play movie files, the movie files with low frame rate can be played more smoothly and the movie files with high frame rate can be played in line with the look and feel of the human eye.
