Abstract
Nowadays, ultrasound imaging (US) has made extensive applications in the field of the medical imaging due to its particular advantages, in which the transducer plays an important role. The traditional single-frequency transducers can not meet the requirements of various medical applications, such as harmonic imaging (HI), second-order ultrasound field imaging (SURF) and acoustic radiation force imaging (ARFI). Therefore, multi-frequency, especially dual-frequency (DF) transducers are proposed, each of which transmits and/or receives the ultrasound in different frequencies. The multi-frequency transducer configurations mainly contain five types which named vertical stack, horizontal stack, transducers with polyvinylidene fluoride (PVDF) layer, interleaved arrays and annular array. In this paper, the design, fabrication and recent developments of the multi-frequency transducers are presented and compared by defragmenting more than a hundred papers.
