Multi-channel surface receiver arrays are a popular
approach for improving the signal-to-noise ratio (SNR)
in MRI when sample noise is dominant1. It has been
demonstrated that even at the center of the human head
where conventional circularly polarized birdcage coils
perform very well, the SNR can still be significantly
increased by using a receiver array2. In order to
support their functionality, multi-channel receiver
systems are normally required on a MRI scanner. The aim
of this study is to develop an onboard RF combination
circuit that can support multi-channel signal reception
with fewer or just one RF receiver channel.
