Abstract

A device is disclosed that includes an array of transducer elements that exhibit space- filling, aperiodic placement. The disclosed placement of transducer elements reduces grating lobe artefacts, facilitates full three-dimensional steerability, and permits maximal power delivery. The disclosed device may be used in a variety of applications and implementations, e.g., as an ultrasound transducer that is adapted for therapeutic purposes, such as hyperthermia or drug delivery. In such applications, the disclosed transducer meets requirements for spatial localization and power delivery.
