High-resolution cross-section magnetic resonant image of a Plantago asiatica was taken with a 990micron, 45-turn square rectangular spiral surface radiofrequency coil in a 3 Tesla Bruker Biospin MRI machine. This coil is produced by standard CMOS microfabrication technique on silicon substrate, with a 5um line width and spacing. The coil is designed to observe biological subjects at the microscopic scale. Though the resulting image quality did not meet the theoretical predictions, it still demonstrates the imaging feasibility of standard CMOS microfabricated coils. Further optimization and improvements of the coil and sample loading mechanism are required.
