摘要：
A low field MRI instrumental system (1) comprises : an electromagnetic Radio Frequency antenna (10) to emit RF pulses for inducing Electron Paramagnetic Resonance ; an electromagnetic Low Frequency antenna (20) for measurements, to emit LF pulses for inducing Nuclear Magnetic Resonance, respectively to receive LF signal produce by NMR; a gradient generator (30), to create a gradient in a static magnetic field generated during measurements; a high field generator (40) to generate a strong pre-polarization magnetic field for magnetic pre-polarization; and, a control/command unit (60). This low field MRI instrumental system (1) is characterized in that it further comprises a low field unit (50) to generate a low static magnetic field whose direction is adjustable along the three directions X, Y and Z of a fixed reference frame associated with the low field MRI instrumental system.
