Ultrasonic blood flow measurements: transcutaneous compared with implanted cuff.


Experiments were undertaken in our laboratory to establish relationships between flow parameters calculated from implanted ultrasonic cuff signals and those obtained with a transcutaneous probe. Analog signals were received from crystals surgically implanted on the right carotid, right femoral, and abdominal aorta of a mature male beagle dog. Near these… (More)
