Claim 13:
14. The method according to claim 12, wherein the first angle is determined in accordance with the formula:

α=K1*a tan 2(K3*dBz/dx,dBx/dx),

wherein α is the first angle, a tan 2( ) is the two-argument arctangent function, dBx/dx is the first magnetic field gradient, dBz/dx is the third magnetic field gradient, and K1 and K3 are predefined constants; and
wherein the second angle is determined in accordance with the formula:

β=K2*a tan 2(K4*dBz/dy,dBy/dy),

wherein β is the second angle, a tan 2( ) is the two-argument arctangent function, dB y/dy is the second magnetic field gradient, dBz/dy is the fourth magnetic field gradient, and K2 and K4 are predefined constants.
