Abstract
This Paper describes the design and construction of 3 MHz medical ceramic transducers with single- and double-matching to a tissue loading for pulse-echo operation. Different impedances of the backing material were used to provide bandwidths between 20 and 80% of the centre frequency. The influence of both the backing and matching are discussed with reference to the admittance function for several construction stages. The measured admittance functions are compared with calculations based on Mason's model and with the measured power transfer and efficiency functions.
