摘要:
Wireless markers having predetermined relative positions with respect to each other are employed for motion tracking and/or correction in magnetic resonance (MR) imaging. The markers are inductively coupled to the MR receive coil(s). The correspondence between marker signals and markers can be determined by using knowledge of the marker relative positions in various ways. The marker relative positions can be known a priori, or can be obtained from a preliminary scan. This approach is applicable for imaging (both prospective and retrospective motion correction), spectroscopy, and/or intervention.
