Abstract

In conventional ultrasonic monitoring of high intensity focused ultrasound (HIFU) treatment, it has been difficult to track the target region when the tissue to be treated deviates from the imaging plane along the elevation axis of the 1-D probe. A 2-D phased array probe providing 3-D imaging capability requires a large number of elements and it is very expensive to build a system to drive all channels simultaneously. A 1.5-D phased array probe can provide a good compromise between conventional 1-D and 2-D phased array probes and has significant cost and implementation advantages. In this study, a new 1.5-D phased array probe consisting of 64×4 elements was designed and developed to track tissue motion within mm order along the elevation direction and the elevational displacement range where the tissue tracking is effective was investigated.
