As coil arrays have increasing number of channels, coil
element continues to shrink. Therefore the noise
originating from coil matching-networks should be
considered explicitly. Here,we calculate the
matching-network noise and define the concept of a
matching-network noise dominating regime, which is a
similar concept to the sample noise dominating regime. A
criterion determining when the matching-network noise
dominates is also formulated in the abstract.
