Ultrasound has considerable potential to accurately and precisely grade beef. Currently, beef quality grades (taste and tenderness) and yield grades (amount of meat) are assigned by a human who visually inspects and subjectively assigns a grade to a beef carcass. The ultimate goal of this work is a an automated and objective grading process. The current phase of the work is not to construct an ultrasound grading device but rather to determine which of these ultrasound related and derived quantities best correlate to each grade. In order to make this determination, an ultrasound data acquisition system capable of acquiring large amounts of high-quality RF data from beef carcasses has been constructed. This paper presents the engineering concepts and construction details of an ultrasound data acquisition device to be used as a research tool for this application.
