This research proposed a new design of helmet-shaped array transcranial magnetic stimulation coil system. It was constructed using several sagittal directional wires and several coronal directional wires. By varying the current direction and strength on each wire, this array coil system could be constructed into the circular coil and figure-eight coil of different size. Also, this proposed coil...

BACKGROUND AND PURPOSE Reported rates of recanalization following coil embolization vary widely across studies. Some confounders are known to affect outcomes but others remain questionable. In the current study, we assess differences in reported angiographic outcomes for cerebral aneurysms treated with coil embolization as a function of single vs multiple readers and site investigator vs core l...

A small pancake coil was wound using 1.2m long, 10 mm wide YBCO coated superconductor tape with impregnation by epoxy resin. The coil was immersed in liquid nitrogen and tested in several regimes. In the DC regime, we measured the I-V curve, the hysteresis of the magnetic field-current curve at liquid nitrogen temperature and the radial component of the coil field at the coil edges. The critica...

OBJECTIVE Accurate and reproducible coil positioning is important for headache research using transcranial magnetic stimulation protocols. We aimed to design a transcranial magnetic stimulation coil holder and demonstrate reliability of test-retest coil positioning. METHODS A coil holder was developed and manufactured according to three principles of stability, durability, and three-dimension...

OBJECTIVE To evaluate a novel test for dynamic visual acuity (DVA) that uses an adaptive algorithm for changing the size of Landolt rings presented during active or passive head impulses, and to compare the results with search-coil head impulse testing. DESIGN Prospective study in healthy individuals and patients with peripheral vestibular deficits. SETTING Tertiary academic center. PARTI...

Introduction: In previous work, we introduced the concept of the multimode coil [1]. The multimode coil consists of a tracking coil connected in series with a multi-turn imaging coil and simultaneously performs the functions of active tip tracking, imaging and inductively coupled wireless marker. The tracking and imaging coils have conflicting design requirements. While the region of sensitivit...
