Keywords: MR-Guided Interventions, RF Arrays & Systems, Transcranial Magnetic Stimulation, Cocurrent TMS-fMRI
Motivation: Concurrent TMS-fMRI lacks whole-brain coverage or has low SNR.
Goal(s): Develop setups allowing for whole-brain TMS-fMRI with high spatiotemporal resolution and minimizing the interference between MRI and TMS during data collection and neuromodulation.
Approach: Combinations of 8- and 16-channel arrays enabled whole-brain TMS-MRI with 16 or 24 channels.
Results: Structural and functional images of high spatiotemporal resolution (1.5 mm with 2 s/volume or 5 mm with 0.1 s/volume) were demonstrated with an MRI-compatible TMS coil.
Impact: We developed concurrent TMS-MRI setups with whole-brain coverage and high spatiotemporal resolution using combinations of 8- and 16-channel coil arrays. Images of high spatiotemporal resolution were demonstrated.
