    摘要: A method of detecting an internal flaw in a particulate filter includes a step of coupling ultrasonic transducer with the particulate filter. The method also includes a step of moving at least one of the ultrasonic transducer and the particulate filter relative to the other. Consistent coupling of the ultrasonic transducer with the particulate filter is maintained during the moving step. Ultrasonic energy is transmitted from the ultrasonic transducer through a majority of a volume of the particulate filter. The method also includes a step of determining if the particulate filter includes an internal flaw using the ultrasonic energy.
