Abstract:

The design and construction of a relatively simple and inexpensive ultrasonic dimension gage sonomicrometer are described in detail. Two piezoelectric crystals are installed surgically across the organ to be studied, and the transit time for a burst of ultrasound to pass from one crystal to the other is measured. The device is easily calibrated when sound velocity in the medium is known. By use of integrated circuits throughout, it may be duplicated for less than 55. Possible applications other than continuous measurements of organ size are discussed.
