Digital receiver technology is relatively a new comer to the field of MRI and it offers great opportunity for customization and research. The purpose of our work was to show how developments in digital communication technology may be used to used as MR receiver chains such that each receive channel is optimized to acquire data from an individual coil in the phased array. The findings showed that by decreasing receiver bandwidth and digital filtering it is possible to reduce noise power, thus by matching receiver channel to individual coil signal from phased array coils could be optimized.
