Abstract
In biomedical ultrasound, experimental work may be performed at various temperatures whereas hydrophone calibration data are typically specified at only one temperature. It is necessary to know the temperature dependence, if any, of hydrophone sensitivity. Comparison of the results of a three-transducer reciprocity calibration of an Imotec type 80-0.5-4.0 passive PVDF probe at 3/spl deg/C, 15/spl deg/C and 37/spl deg/C to the calibration at 22/spl deg/C show that within the limits of precision of this experiment, there is no difference in hydrophone sensitivity at these four temperatures.
