Abstract
Embodiments for testing an acoustic property of an ultrasound probe including a plurality of transducer elements are disclosed. A Shlieren image of an ultrasound probe and a visualized acoustic field of an ultrasound signal generated when one of the transducer elements is excited are acquired. A preprocessing including noise removal and position calibration upon the Shlieren image is then carried out. An acoustic property of the ultrasound probe is tested based on the preprocessed Shlieren image.
