1. A method of calibrating an ultrasound probe, the method comprising:

  • mounting an ultrasound probe having at least one array of ultrasound elements onto a calibration system adjacent to a tank;

    transmitting an ultrasound test signal from a first transmitting element of the probe into the tank and through a test medium of the calibration system;

    receiving the test signal at a first hydrophone disposed in the tank at a first time;

    receiving the test signal at a second hydrophone disposed in the tank at a second time;

    receiving the test signal at a third hydrophone disposed in the tank at a third time; and

    determining an acoustic position of the first transmitting element within a coordinate system defined relative to the probe based upon differences in the first time, the second time, and the third time.
