The theory of a new B‐mode registration test procedure is presented along with experimental verification of the detailed theoretical predictions. The new procedure separately tests the B‐scan articulated arm calibration and the equipment acoustic velocity calibration. Readily verifiable secondary standards are incorporated into the procedure for self‐calibration purposes. The procedure provides a specific and reproducible analysis of angular misregistration errors while maintaining an acceptable level of sensitivity. No coupling gels or oils or operator skill is required. A special test has been found which permits the service person to verify that the equipment is capable of attaining proper B‐mode registration before beginning the recalibration procedure.
