Abstract
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.
