Abstract: Receiver is an important part in MRI system. In MRI application, the receiver should have low noise figure, high dynamic range and high linearity. To achieve these goals, many devices with high performanceare used in MRI receiver, which makes the MRI receiver rather expensive. To decrease the cost of the MRI receiver, the application of AGC technology in MRI receiver is studied in this paper. Pilot signal is introduced for the signal reconstruction to solve the problem of non-linearity caused by AGC.
