The purpose of this study is the optimal design on High Intensity Focused Ultrasound transducer architecture with sparse-element to reduce the number of RF driving channels required for practical implementation for cost- and time-effective HIFU treatment of tumors. For rapid treatment of large-sized tumor while protecting healthy tissues, volumetric ablation by multiple focusing is one of the promising...
In this study, a multiobjective optimization technique developed by the author is introduced to solve the scanning sequence (or switching) plan of multiple-focus patterns, satisfied with the objectives of uniform high dose to the block and fast ablation. In case of multiple focusing, the shape and scan time of the single block which is a fundamental factor for planning the positions of the blocks...
In this study, the optimization framework to seamlessly integrate simulation process for computer simulations which perform from transducer array designs to ultrasound therapy is proposed. The optimization framework consists of three processes: a) design of a random transducer array, b) design of multi-focus patterns and a sparse array, and c) treatment planning of scanning time and path. In an attempt...
