Advancing whole-brain BOLD fMRI in humans at 10.5 Tesla with motion-robust 3D EPI and RF parallel transmission: initial experience

Shuxian Qu, Peter van Gelderen, Jacco de Zwart, Jeff H. Duyn et autres

Motivation: Pursuing quality high resolution BOLD fMRI is a main driver for developing human MRI systems operated at > 10 Tesla (10T). Goal(s): To promote whole-brain BOLD fMRI at 10.5T by combining parallel transmission (pTx), motion-robust 3D EPI, and high-density RF coil …

Generating an EM Simulation Model of a Clinically-Used RF Head Coil at 7T

Dora Özkara, İris Yazıcı, Elnaz Mahmoudalilou, Sascha Brunheim et autres

Motivation: An electromagnetic (EM) simulation model for the Nova 8Tx32Rx 7T Head Coil is not available for analyzing patient safety in 7T imaging applications. Goal(s): Our goal is to create an accurate EM model for the Nova 8Tx32Rx 7T Head Coil and …
