The piezoceramics can be fabricated in a number of ways to perform B-mode imaging. In its simplest form, the B-mode transducer is a circular single-element transducer with a fixed geometric focus. To a large degree this type of a transducer has been replaced today by more sophisticated multielement transducers however, there are still commercial systems where single-element transducers are used. The next more complicated designs are annular arrays, which are also circular but.

In addition to spatial compound and Doppler systems, the beam steering function has recently been applied to B-mode imaging to obtain a parallelogram format with lateral sides parallel but oblique instead of a rectangular field-of-view. This function is obtained by activating consecutive ele-...
