Conformation of ultrasonic vortex beams through the skull using acoustic holograms for particle trapping

Abstract

Acoustic tweezers are a versatile and powerful emerging tool to biomedical applications, such as cell manipulation or drug delivery, as they allow contactless particle manipulation using low-power devices. Single beam acoustic tweezers based on vortex beam require a focused ultrasound beam containing a phase dislocation at its axis. While these beams have demonstrated great potential to trap particles in homogeneous media, phase aberrations produced by strongly heterogeneous and refracting media distorts the wavefront and inhibit the generation of trapping forces. In this work we report a method to conform aberration-free focused vortex beams through the skull for transcraneal particle trapping using acoustic holograms.
