An elongate ultrasound probe (204) including a probe head (214) with a transducer array (216), a handle (208), a flexor (222) located between and affixed to the probe head and the handle, a flexor actuator (224) configured to flex the flexor, and a probe head motion actuator (226) configured to oscillate the flexor actuator and thereby oscillate the probe head. A method includes electronically vibrating a probe head, which includes a transducer array, of an ultrasound probe in connection with ultrasound elasticity imaging.
