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.
