In-vivo detection of oscillatory magnetic field may lead to fundamental development of functional MR imaging. The recently developed spin-lock oscillatory excitation (SLOE) method exhibited sub-nanotesla level of sensitivity. However its application in vivo is troubled by main field inhomogeneity. In this work, an oscillatory-selective detection (OSD) is proposed to overcome this limitation and hence to improve sensitivity of in-vivo detection of oscillatory magnetic field. OSD has also been verified as a viable tool in mapping transcranial alternating current.
