Abstract
This paper describes a series of high intensity focused ultrasound (HIFU) phased array transducers with a single Archimedean spiral close packed element arrangement on a spherical surface extending from the central axis outward. Simulation and measurement reveal using the spiral element arrangement on a spherical bowl reduces grating side lobes while maximizing power density at the focus.
