Intraluminal MRI probe holds promise to achieve high resolution image of small pathological lesion such as the vessel plaque comparing to the conventional MRI scanner. The MR signal receive coil is expected to be characterized by high signal-noise-ratio (SNR), good signal homogeneity and small size. By employing the developed photolithography technology on cylinder substrates, the MRI receive coil for the intraluminal application can be fabricated arbitrarily with the accurate and optimized shape. Comparing to previous single layer coil, this study presents the design of the multilayer receive coil for improving the imaging performance.
