Abstract :
Instead of using a RF coil, a novel MR signal detection method based on optical pumping is introduced. The simulated MR signals are generated via a coil which is mounted around the rubidium vapor cell. By measuring the transmitted light intensity, magnetic fields generated by the coil could be obtained. First of all, a FID signal is detected by this method. Then 1D imaging of two point spins is also presented. Future improvements are discussed at the end of the paper.
