Image-Guided Surgery of Primary Breast Cancer Using Ultrasound Phased Arrays
Abstract
High-intensity focus ultrasound (HIFU) is gaining wider acceptance in noninvasive or minimally invasive targeting of abnormal tissues (e.g. cancer) for destruction. Piezocomposite transducer technology, especially for phased arrays, is providing high-quality HIFU applicators with increased bandwidth and reduced parasitic cross coupling between the array elements. In addition to increasing the efficacy of HIFU applicators, these technological enhancements allow for the use of HIFU arrays in imaging the target region before, after, and intermittently during lesion formation. This leads to a unique paradigm of image-guided surgery with HIFU in which the coordinate systems for both therapy and imaging are inherently registered. This project investigates the feasibility of using piezocomposite phased arrays as dual-mode ultrasound array (DMUA) applicators for the noninvasive treatment of primary breast cancers. Both therapeutic and imaging capabilities of the dual-mode arrays are investigated leading to a real-time dual-mode array system to be used in pursuing in vivo animal experiments in the future.
