Design of a New Dual-Helix Loop Coil for Intravascular MR Imaging

Mohammad Mohammadzadeh¹, Mahmud Shahabadi²

The lack of spatial resolution is an important problem in MR imaging of the vessel wall and plaque structures. To alleviate this problem, researchers have recently developed intravascular coil technology to increase the SNR of MR images. This can then be traded to achieve higher spatial resolution. In this work we present a new dual-helix loop coil design to increase the conventional single-helix loop coil SNR. We show that the SNR distribution around this coil is enhanced over the conventional single-helix coil case.
