A major problem in developing 2-D arrays is the large number of elements required for big apertures in order to produce high quality ultrasonic images. Recent advances in transducer technology have made possible to design arrays with fewer restrictions in the shape and layout of elements. In this paper we propose to use Evolutionary Algorithms to optimize these parameters to obtain large 2-D ultrasonic...
The use of technologies of capacitive micromachined ultrasonic transducers (cMUTs) offers a new way of development ultrasonic transducers. They are built using standard silicon integrated circuit fabrication technology, and this permits to integrate electronic components in the probes, and a more flexible layout of the array elements. If the distribution of the elements of such arrays is periodic,...
