MRI meaning is a Magnetic resonance imaging, generate gradient magnetic field in the big cylinder that man is able to lie down, resonate the man’s cells, and then measure signal,display the imaging by computer.
MRI system use strong magnetic fields and radio waves to form images of the body. The technique is widely used in hospitals for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation
It is a kind of power supply system for generating magnetic field to MRI system coils, depend on magnetic filed force, affect to precision of image. So a gradient Amplifier is a important system to generate resonance magnetic field.
