DOI: 10.1002/bem.22387
Abstract: In pediatric magnetic resonance imaging (MRI), infants are exposed to rapid, time‐varying gradient magnetic fields, leading to electric fields induced in the body of infants and potential safety risks (e.g. peripheral nerve stimulation). In this… read more here.

DOI: 10.1002/mrm.27382
Abstract: As gradient performance increases, peripheral nerve stimulation (PNS) is becoming a significant constraint for fast MRI. Despite its impact, PNS is not directly included in the coil design process. Instead, the PNS characteristics of a… read more here.

DOI: 10.1002/mrm.29452
Abstract: Asymmetric gradient coils introduce zeroth‐ and first‐order concomitant field terms, in addition to higher‐order terms common to both asymmetric and symmetric gradients. Salient to compensation strategies is the accurate calibration of the concomitant field spatial… read more here.

DOI: 10.1109/access.2022.3206357
Abstract: Gradient coils are essential for the performance of magnetic resonance imaging systems. Usually, coils are designed assuming thin wire tracks. Here, we design an MR gradient coil set using a more general approach considering the… read more here.
