Abstract

In an RF power calculation apparatus and method for an MRI system, a first power calculation processor calculates a first power of an RF signal received by a first receiving method, a second power calculation processor calculates a second power of the RF signal received by a second receiving method, a difference calculation processor calculates the difference between the first power and second power, an RF power calculation processor calculates an RF power of the RF signal on the basis of the first power and second power when the difference is smaller than a first threshold.
