Abstract
A RF receiver system for an MRI apparatus includes a receive coil, which exhibits a total effective coil impedance composed of the coil impedance of the coil itself and a patient impedance. An analog-to-digital converter is connected to an amplifier for converting the amplified output signal from the amplifier to a digital signal for further processing. A matching network is interconnected between the receive coil and the amplifier and includes a matching system with an adjustable impedance for matching the total effective coil impedance to the lowest noise impedance, and a noise calculation unit is connected to the analog-to-digital converter for receiving the digital output signal of the converter and is configured to calculate noise of the output signal of the analog-to-digital converter and for adjusting the adjustable impedance of the matching network in order to calibrate the matching network for every patient individually before the scanning process.
