Abstract
A new configuration of ultrasound array transducers is proposed whose element boundaries interlock in a fine pattern to eliminate grating lobes from the acoustic field without using a very large number of array elements. Two dimensional acoustic fields produced by interlocking element 3.5 MHz array transducers are computer-simulated. These acoustic fields are compared with those from the corresponding conventional array transducer with straight-line element boundaries. The new configuration reduces grating lobe intensity by 20 dB in a round trip acoustic field and virtually eliminates grating lobes.
