Diagnostic ultrasonography of the bottlenose dolphin was investigated in order to establish normal acoustical anatomy, windows available for sonographic viewing, applications in monitoring pregnancy and as a diagnostic aide in pathological conditions.

CAT scans as well as sections of post mortem specimens were utilized to demonstrate cross-sectional anatomy as it relates to ultrasonic imaging. Ultrasonic examinations of T. truncatus were performed using 2.25, 3.5, 5 mHz sector transducers with animals unrestrained in the water and manually restrained on the deck.

CAT scans, post mortem sections and video tape of the nation procedure and ultrasonic imaging of normal and pathological conditions will be presented. Future applications will be discussed.
