摘要: In one example, a method for acquiring a medical image includes activating a body radiofrequency (RF) coil in a body coil receive mode to obtain body calibration information of a subject. The method further includes, while the body RF coil is in the body coil receive mode, activating a surface RF coil in a surface coil receive mode to obtain surface calibration information of the subject, and correcting a reconstructed image with an intensity correction filter determined from the body calibration information and surface calibration information.
