Another application is in therapeutic ultrasound. Researchers in the field of HIFU not only want to direct the delivery of energy in multiple planes, but also want to know how the tissues adjacent to the treated tissue are responding to that energy. A matrix array, controlled by a high-channel-count system, can facilitate these objectives.
Finally, there is another potential for high-channel-count systems in the area of aberration correction. With conventional 2D imaging there is often image degradation due to echoes produced by out-of-plane structures. These structures are not visible, but the artifacts they produce can create confusing and misleading information. Current techniques for aberration correction can address artifacts that arise from in-plane structures, but not those from structures that lie out of the scan plane. A matrix array transducer, controlled by a high-channel-count system, provides opportunity for the researcher to detect and mitigate these artifacts.
