Abstract

See full text

A dual frequency ultrasound transducer includes a high frequency (HF) transducer and a low frequency (LF) transducer that is positioned behind the high frequency transducer. An intermediate layer is positioned between the low frequency transducer and the high frequency transducer to absorb high frequency ultrasound signals. An alignment feature on the low frequency transducer is positioned with respect to a fiducial that is marked at a known position with respect to high frequency transducer elements of the HF transducer to align low frequency transducer elements of the LF transducer with the HF transducer elements.
