Focused Ultrasound Help Realize High Spatiotemporal Brain Imaging?-A Concept on Acousto-Electrophysiological Neuroimaging.
Authors: He B
We present a concept for integrating focused ultrasound (FUS) with electrophysiological neuroimaging, in order to achieve high spatiotemporal resolution brain imaging. This approach, which we are tentatively calling acousto-electrophysiological neuroimaging, leverages on the spatial focality and noninvasiveness of FUS and may potentially lead to a noninvasive human brain imaging modality with high resolution in both space and time domains. By the use of modulated FUS, spatial selectivity can be accomplished for high-resolution electrophysiological neuroimaging. Frequency shifting in resulting magnetic signals (using modulated FUS) may potentially open the door for a room temperature magnetoencephalography device.
Introduction
Purpose
Other
Study Objective
To propose integrating focused ultrasound with electrophysiological neuroimaging—acousto-electrophysiological neuroimaging—to enable noninvasive high spatio-temporal resolution brain imaging and potentially room-temperature MEG.
Outcomes and Safety
Summary of Outcomes
No biological or behavioral effects were reported; the paper proposes that modulated focused ultrasound can provide spatially selective high-resolution electrophysiological neuroimaging and that frequency-shifted magnetic signals from modulated FUS might enable room-temperature MEG. No specific focused ultrasound parameters were tested or validated in this work.
Safety-related matter
The paper does not mention any safety issues or adverse effects; no statements about safety testing or potential risks are provided.
