A design for a high-density focused ultrasound array addressing and driving system

The feasibility of using focused ultrasound as an effective means of destroying malignant and benign tumors has been demonstrated in numerous studies. Research into methods for delivering the energy used in therapeutic applications has primarily used multi-element arrays, with phased array techniques offering the most flexibility. While these methods have proven effective in the ablation of tumors in vivo, limitations exist in several areas, which have prevented further advances from being made. In order to achieve tighter control over focal volume and increase beam steering capabilities, the number of elements used in phase array design will have to be increased. However, issues related to cost, matching, interconnects and cable assembly size have prevented high-density arrays from being realized as a practical means for treatment. The goal of this research was to demonstrate the feasibility of designing and testing a relatively low-cost system that could effectively drive several thousand elements, while minimizing the size of the cable assembly that delivers power to the array.
