It is technically challenging to design compact and sensitive, yet low SAR catheter RF coils for endovascular MR imaging. In this work, we investigate a catheter coil design technique based on transmission line resonator. The catheter coil is designed and constructed for vascular imaging at 1.5T. The imaging comparison between catheter coil and body coil demonstrate that the catheter coil has a significant SNR gain over the use of body coil at 1.5T.
