A Fully Electronically Steerable Therapeutic Ultrasound Phased Array With MR-Guidance.

Unlabelled: Recently, MRI-guided focused ultrasound (FUS) has shown great promise in treating various conditions non-invasively.

Objective: The focus of this article is to introduce an MRI-guided FUS device, which can provide full electronic steering range without mechanical movement and with low near-field heating. A pilot study was conducted in order to investigate the feasibility, and safety of the device in a large animal model and a pilot clinical trial.
