ABSTRACT:
A method and apparatus for storing data signals, which data signals comprise radio frequency ultrasonic signals from an ultrasonic transducer and positional signals from a source associated with the transducer, wherein the signals are converted into a format in which they are compatible with a video recorder and stored on video recording magnetic tape for reproduction as required. Because the data signals are recorded live rather than in the form of a cathode ray oscilloscope display, they can be rectified as necessary. Positional coordinates of the transducer may be stored, and scans at varying thresholds can be reproduced. Position and ultrasonic data signals are interleaved on the video recording magnetic tape. Apparatus for performing the method includes a video recording device having a rotatable head and interface units for converting the radio frequency signals into television format and for decoding the signals for reproduction.
