Preliminary results relating to the design, fabrication, and characterization of a 60 x 60 (3600) element (fully sampled) 5 MHz 2D array are presented here. Our earlier array used 32 x 32 (1024) elements and 3.3 MHz resonant frequency enabled approximately 0.5 mm resolution images. The ‘live’ element yield was estimated at 98.3% by recording the impedance of 169 regularly spaced elements in the array. Pulse-echo experiments indicated that the system operating frequency was 4.2 MHz 9% below the… CONTINUE READING
