Motion tracking in magnetic resonance imaging using radar and motion detection systems

摘要

The present invention provides medical devices 100, 300, 400, 500 including magnetic resonance imaging system 102.The medical device further comprises a subject support 120 having a support surface 121 configured to support at least a portion of the subject within the imaging zone 108.The subject support comprises a radar array 125 embedded under the support surface.The medical device further comprises a radar system 124 for acquiring the radar signal 144 from the subject.The medical device further comprises a motion detection system 122 configured to acquire motion signals 146.The execution of the machine executable instruction 140 is stored in the processor 130Continuously receive the radar signal (200);Continuously receive motion signals (202);The synthetic motion signal 148 is calculated from the radar signal and the motion signal continuously (204);A magnetic resonance imaging system is controlled using a pulse sequence command to obtain magnetic resonance imaging data (206)The acquisition of the magnetic resonance imaging data is controlled using the synthesized motion signal.
