Abstract

Deep brain stimulation (DBS) is a clinical tool adopted to treat various neurological disorders, including chronic pain, incontinence and movement disorders. One major limitation of commercial DBS systems i. The inability to controy the distribution oy the electric field aroun. The target region, resulting i. The activation of both target and non-target neural clusters. The authors have previously proposed a method to provide controlled stimulation by the adoption of phased array technology. A model was developed to stud. The behavior of wavefronts, generated by phased arrays, in tissue. This study represents an improvement to this model, wher. The frequency-dependence oy the dielectric properties of brain tissue is taken into account. Results have shown that the applicability of phased array stimulation depends oy the frequency of stimulation, with frequencies i. The region of GHz providin. The best trade-off between field steering, focusing and tissue penetration.
