Claim 6:
7. The method of claim 1, wherein the real-time target magnetic field information of the target subject located in the main magnetic field and the plurality of gradient magnetic fields is used for determining posture information of the target subject, the posture information reflecting a posture motion of the target subject, wherein the posture information of the target subject is determined by:
determining second position information of a plurality of positions of the target subject corresponding to the plurality of time points, a plurality of diamond NV center sensors being disposed on the plurality of positions of the target subject;
for each time point of the plurality of time points, determining a contour of the target subject corresponding to the time point based on the position information of the plurality of positions corresponding to the time point, the contour of the target subject being formed by an edge of a surface of the target subject; and
determining the posture information of the target subject based on the plurality of contours of the target subject corresponding to the plurality of time points.
