The Ultrasound Time-Domain Correlation (UTDC) technique involves the determination of a similarity factor, the correlation coefficient. For this application, UTDC was used to calculate the maximum correlation coefficient between RF echo signals of porcine muscle tissue obtained at different times and for different echo spacings. The porcine muscle samples were procured from a slaughterhouse and data acquisition began within 1.5 hours post mortem. The echo signals were obtained with a customized ultrasound data acquisition system and analyzed using a 486 PC. The results indicated that observed trends in the correlation coefficient could be used to determine muscle activity post mortem and when this activity stoped, approximately 10 hours post morem. This paper presents a explanation of the methods used and the results obtained.
