Abstract :
A dual frequency probe composed of two outer low frequency arrays and one inner high frequency array is designed through a simulation stage, manufactured and fully characterized. Electroacoustical, acoustical and electrical properties suited the imaging modalities requiring an ultra wide bandwidth. The presented array transducer is a 128 elements linear array for superficial imaging with targeted frequency range from 2 MHz to 10 MHz. Electroacoustic and acoustic performances measured are close to those simulated. The device provides an ultra wide bandwidth of 130% improving superharmonic imaging.
