Novel Design of Hollow Coils for TMS to Minimize the Heat without Reducing Magnetic Field Intensity

Transcranial magnetic stimulation (TMS) is a non-invasive neurom odulation technique used to treat various neurological disorders, including major depression. Since the cerebellum complex structure connected almost throughout central nervous system, TMS has gained popularity in field of cerebellar neurostimulation and promises stimulate activity non-invasively. The coil material play significant roles achieving focality coil. However, few studies have proposed structures solid coils, such as figure-of-eight (FOE) butterfly-shaped coils increase it observed that there always trade-off between intensity temperature In this study, new designs were reduce without significantly reducing intensity. Finite-element simulation tools ANSYS Maxwell® FEMTET® simulate thermal analysis. design included hollow double-layered enamel-layered coils.
