Embodiment Construction
[0040] refer to figure 1 , shows an MRI scanner to which the scheme according to one embodiment of the invention is applicable. The scanner 100 includes a table 105 on which a patient 110 lies for analysis. The platform 105 can slide inside the tunnel 115 . The tunnel 115 houses a permanent magnet 120 that generates a very high static magnetic field Bo (eg, on the order of 1-9T). Multiple sets of gradient coils 125 (typically three sets of gradient coils 125, each for a different direction) are coupled to the magnet 120 for adjusting the magnetic field Bo. The tunnel 115 also houses a radio frequency (RF) coil 130, which applies a magnetic pulse B1 to a particular body part of the patient 110 to be analyzed and receives an RF magnetic response signal returned by the same body part; 110 is designed for the type of body part (eg, shoulder, knee, spine, head, etc.) with different configurations (eg, surface coil, saddle coil, Helmholtz coil, etc.). Tunnel 115 has magnetic shi...
