The ultrasonic study of thoracic and abdominal viscera was realized on
3 cynomolgus monkeys. The exploration procedure was defined for the h

the cynomolgus anatomical characteristics. Considering the high qualit
y images, this kind of exploration appeared to be particularly suited
for studies requiring morphological and functional examinations of the
heart.
