Abstract:
1. An asymmetric ultrasound transducer comprising: (a) the asymmetric ultrasound transducer arranged in a plurality of ultrasound transducer elements in a two-dimensional phased array comprising at least a first region of a first plurality of rows and columns of grouped transducer elements extending over a first contiguous area and including only transducer elements of the first region and a second region of a second plurality of rows and columns of grouped transducer elements extending over a second contiguous area, wherein the second contiguous area is different from and not overlapping with the first contiguous area, and the second contiguous area including only transducer elements of the second region; (b) a first plurality of signal channels connected to and collectively driving the transducer elements of the first region, and the signal channels are configured to generate a first ultrasound beam and a first focus, the elements within each group being connected to the same signal channel and the elements configured to be driven together with the same drive signal; and (c) a second plurality of signal channels connected to and collectively driving the transducer elements of the second region and the signal channels are configured to generate a second ultrasound beam and a second focus, the elements within each group being connected to the same signal channel and the elements configured to be driven together with the same drive signal, (d) the asymmetric ultrasound transducer configured to ablate tissues [0003], [00051] and configured to provide simultaneous treatment with other treatment equipment [0024].
