Magnetic resonance-guided focused ultrasound (MRgFUS) is a non-invasive treatment that uses sound waves to treat conditions like essential tremors, and it’s being studied for other issues like pain. Unlike traditional treatments like deep-brain stimulation, MRgFUS doesn’t require surgery. During MRgFUS treatment, special ultrasound equipment is placed on the head, and it needs to be adjusted to focus precisely on the target area, which sometimes requires a large opening in the head coil used for imaging. In this study, researchers tested six different designs for these coils and measured how well they worked, looking at factors like signal clarity and image quality using a computer model of the human head. The goal of the study is to help create better coil designs that are compatible with MRgFUS treatments.
