Transcranial Focused Ultrasound Modulates Electrical Behavior of the Neurons: Design and Implementation of a Model
Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures. The primary capability of this method is the improvement in the treatment progress of certain neurological and psychiatric disorders noninvas...
متن کاملNoninvasive functional neurosurgery using transcranial MR imaging-guided focused ultrasound.
UNLABELLED Transcranial magnetic resonance imaging-guided focused ultrasound (tcMRgFUS) is a novel technique to supplement the spectrum of established neurosurgical interventions. In contrast to traditional ablative procedures, tcMRgFUS is noninvasive and entirely imaging-guided with continuous temperature measurements at and around the target in real time. It has no trajectory restrictions and...
متن کاملTime-course Characterization of High-intensity Focused Ultrasound Exposure Using B-mode Ultrasound Imaging
High-Intensity Focused Ultrasound (HIFU) is an emerging non-invasive surgical technique. HIFU systems are generally designed to deliver a fixed amount of energy to tissue, but because the tissue thermal response is variable across patients and tissue type, this approach can often lead to underdosing or overdosing. In order to improve the dosing precision in HIFU we are investigating real time m...
متن کاملTranscranial Focused Ultrasound Modulates Intrinsic and Evoked EEG Dynamics
BACKGROUND The integration of EEG recordings and transcranial neuromodulation has provided a useful construct for noninvasively investigating the modification of human brain circuit activity. Recent evidence has demonstrated that focused ultrasound can be targeted through the human skull to affect the amplitude of somatosensory evoked potentials and its associated spectral content. OBJECTIVE/...
متن کاملIn Vitro and In Vivo Investigation of High-Intensity Focused Ultrasound (HIFU) Hat-Type Ablation Mode
BACKGROUND The aim of this study was to investigate the feasibility of the application of high-intensity focused ultrasound (HIFU) hat-type ablation mode in in vitro and in vivo models, and to compare the ablation effects of different parameter combinations. MATERIAL AND METHODS HIFU hat-type ablation was performed in isolated bovine liver tissue and in the liver tissue in living rabbits, and t...
