title: A simple optical method for observing medical ultrasound pulse characteristics in vitro.
abstract: An optical method is described for studying the spatial and temporal characteristics of broad-band ultrasonic pulses propagating in transparent media. The simplicity of the approach suggests its consideration as a method for calibration and comparison of the transmitted pulse characteristics of medical ultrasound systems.
