Resonant field imaging

WebMany of the thermal and electrical burns caused by medical processes stem from magnetic resonance imaging machines. MRI injuries are caused by heat; as the MR field strength increases, the heating potential also increases. The electrical properties of the medium surrounding antennas play an important part in amplifying the antenna effect. WebNuclear Magnetic Resonance When a magnetic nucleus is located in a strong magnetic field, it resonates. In effect, it becomes a tuned radio receiver and transmitter. The resonance occurs because the spinning nucleus precesses at a rate that is in the radio frequency range. The resonant frequency is determined by three factors.
