“…These machines range from the Scanogram which incorporates a modified linear scanning technique using a single ultrasonic transducer (Stouffer, Wallentine, Wellington and Diekmann, 1961) to more complex 'real time' machines such as the Danscanner which has an array of transducer elements.

Measurements of the m. longissimus and overlying fat at the last rib were taken on the live pig u'ing ultrasonic machines of differing complexity: Sonatest (simple A-mode machine), Scanogram and His Observer (modified linear scanners), and Danscanner ('real time' scanner). These measurements were examined as predictors of the corresponding carcass measurements and percentage lean in the carcass. Sonatest and Scanogram were compared using 143 purebred and crossbred pigs of different types. The analysis was pooled within breed-type and sex. The standard deviation for percentage lean was 3-94. Residual standard deviations for predicting percentage lean from live weight and best fat thickness were 2-72 (Sonatest) and 2-56 (Scanogram). Addition of m. longissimus depth (Sonatest) and m. longissimus area (Scanogram) reduced these to 2-69 and 2-29 respectively. The use of two or more fat measurements provided no extra precision over a single fat measurement. Scanogram and His Observer were compared using a subset of 38 pigs. Scanogram was a better predictor of percentage lean using a single fat measurement but when a combination of measurements was used, there was little difference between the machines. Scanogram and Danscanner were compared using a subset of 27 pigs. The standard deviation of percentage lean was 3-57. Residual standard deviations for predicting percentage lean from live weight, best fat depth and m. longissimus area were 2-18 (Scanogram), and 2-03 (Danscanner). Fat areas had similar predictive precision to fat thickness measurements.

“…By the early 1960s a pioneering technique in the use of ultrasound for animal science purposes was introduced: a continuous mechanical scanning procedure (Stouffer et al ., 1961). An electric motor was mounted on a thick rubber belt that was placed on the animal's back.…”

Abstract:In this chapter the use of real-time ultrasonography to predict in vivo carcass composition and meat traits will be reviewed. The chapter begins by discussing background and principles of ultrasound. Then aspects affecting the suitability of realtime ultrasonography and image analysis for predicting carcass composition and meat traits of meat producing species and fish will be presented. This chapter also provides an overview of the present and future trends in the application of real-time ultrasonography in the meat industry.
