Peripheral nerve stimulation properties of head and body gradient coils of various sizes.
Peripheral nerve stimulation (PNS) caused by time-varying magnetic fields has been studied both theoretically and experimentally. A human volunteer study performed on three different body-size gradient coils and one head-size gradient coil is presented in this work. The experimental results were used to generate average PNS threshold parameters for the tested gradient systems. It was found that...
متن کاملDefinition of Peripheral Nerve Stimulation
that is rapidly gaining popularity for a variety of clinical conditions. Despite its straightforward nature, the modality has been for a long time treated as a ‘stepchild’ of the neuromodulation field, yielding the spotlight to the more ubiquitous spinal cord stimulation (SCS) and the more elegant deep brain stimulation (DBS) approaches. Interestingly enough, the main theoretical explanation of...
متن کاملActive localized shielding for devices within MRI gradient coils
Introduction There are an increasing number of applications in which non-MRI active or passive devices are being introduced into the MRI system and required to operate normally while exposed to the static, RF, and audio-frequency (i.e. gradient) magnetic fields produced during normal scanning. In this abstract, we focus on gradient fields and consider the possibility of designing a very localiz...
متن کاملOptimization of Biplanar Gradient Coils for Magnetic Resonance Imaging
“Open” magnetic resonance imaging (MRI) scanners are frequently based on electromagnets or permanent magnets, and require self-shielded planar gradient coils to prevent image artifacts resulting from eddy currents in metallic parts of the scanner. This work presents an optimization method for the development of self-shielded gradient coils with biplanar geometry for “Open” MRI scanners. Compare...
متن کاملPerspective: Peripheral nerve stimulation and peripheral nerve field stimulation birds of a different feather.
SCS has positively impacted the life and function of thousands. In contrast, stimulation of the peripheral nervous system, also FDA-approved for limited use, is employed to treat neuropathic pain arising from peripheral nerve dysfunction. Two, distinct therapies exist: 1) Peripheral Nerve Stimulation (PNS) therapy, which provides stimulus to a named nerve that innervates an area and 2) Peripher...
