Classification: CPC G  H | IPC G  H

Claim 6:
7. The device as claimed in claim 5, further comprising: a fourth operational amplifier, a seventh resistor, an eighth resistor, and a ninth resistor, wherein:
the first connection terminal of said seventh resistor is connected to the output terminal of said first LDO, and the second connection terminal of said seventh resistor is connected to the first connection terminal of said eighth resistor;
the first connection terminal of said eighth resistor is connected to the output terminal of said second LDO;
the non-inverting input terminal of said fourth operational amplifier is connected to the second connection terminal of said seventh resistor;
said ninth resistor is connected between the inverting input terminal and the output terminal of said fourth operational amplifier;
the resistance value of said seventh resistor is equal to that of said eighth resistor;
if the MRI system detects that a difference between the output voltage of said fourth operational amplifier and that of said first LDO is within the preset range, it is determined that the output of said first LDO is balanced with that of said second LDO; and
if not, it is determined that the output of said first LDO is unbalanced with that of said second LDO.
