1. An ultrasonic signal processing system for an ultrasonic transducer, comprising:

  • transducer control and signal digitizing means for controlling transmit signal production, digitizing reflection signals and indicating transducer position; and

    flaw indication processing means for storing the digitized reflection signals as a reflection waveform, comparing the reflection waveform to a threshold waveform, producing and storing flaw indications when the reflection waveform exceeds the threshold waveform, and storing the transducer position in association with the flaw indications.
