Medical piezoelectric ultrasonic transducer and their performance analyses

Piezoelectric ultrasonic transducer is the transducer which is technically designed for electrical measurement of non-medical electrical capacity, some physiology parameters of human body like blood pressure, pulse, breathe, body temperature, and etc. are non-electrical capacity. In order to measure these physiological parameters, the simplest way is to change them for the project is technically easier for measuring the amount of electricity (or called telecommunications), then the telecommunications which is equivalent to some of these physiological parameters to be enlarged, and measured, the medical transducer is the completion of the conversion of such devices. This article discussed the classification, structure and main performance index, and their meaning and application of the concept of volume, and introduced the medical application of the more important the concept of resolution and its transducer performance.
