title: Acoustic properties of some biocompatible polymers at body temperature.
abstract: In response to the many invasive applications of ultrasound which are developing, the acoustic properties of several aliphatic and aromatic polyurethanes and Polyether block amide (PEBA) copolymers are presented. These polymers were reported by their manufacturers as being biocompatible and are possibly suitable for short-term implantation in humans. Speed and attenuation of sound are measured at 37 degrees C as a function of frequency by use of a Fourier-transform method. These properties are reported in tabular and graphic form.
