Background, Motivation and Objective To accurately monitor HIFU therapy and three-dimensional target motion estimation using a broadband spherically focused HIFU array transducer with a Verasonicsplatform. The described series of dual-mode HIFU array transducers use a single Archimedean spiral close packed element arrangement. Earlier work has shown thisarrangement to adequately reduce grating lobes and unwanted therapy outside of the intended focus. This paper shows parallel advantages in reducing grating lobes andmaximizing therapy monitoring accuracy.
