Show abstract
BackgroundConcurrent transcranial magnetic stimulation (TMS) and magnetic resonance imaging (MRI) is time-consuming because of the limited space in the MRI bore and the sophisticated placement and orientation of the TMS coil to elicit the desired brain activities and behaviors. ObjectiveWe developed a TMS coil holder capable of quick adjustment of the TMS coil position and orientation. The holder can also hold an MRI receiver coil array. MethodsA holder with one controlling knob, two omni-direction rotation joints, and two in-plane rotation joints was developed. ResultsDifferent TMS coil positions and orientations can be arranged and fixed in seconds. The holder can also accommodate two TMS coils to allow for multi-coil TMS-MRI. ConclusionOur development significantly improves the workflow of the concurrent TMS-MRI in new neuroscience studies and clinical applications.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
