1. A system for testing an acoustic property of an ultrasound probe including a plurality of transducer elements, comprising: an image acquisition unit configured to acquire a Schlieren image of the ultrasound probe and a visualized acoustic field of an ultrasound signal generated when one of the transducer elements is excited; and an acoustic property testing unit configured to perform preprocessing including noise removal and position calibration upon the Schlieren image, and test an acoustic property of the ultrasound probe based on the preprocessed Schlieren image.
