ULTRASONIC STUDIES OF PRESERVED PEACHES

A conventional clinical ultrasonic B-scanner has been successfully use d to image preserved (canned) peaches, with a view to assessing the me thod's potential for detecting stone pits embedded in the peach flesh. In addition, it is suggested from the pictures obtained that the grey scale texture arising from the peach flesh may be indicative of varia tions in the degree of ripeness of the peach prior to preservation. Th e acoustic velocity and attenuation in the peaches appear to be close to those of soft tissues, and preliminary laboratory measurements conf irm this.
