We present a novel “Less-for-More” concept for array coil by joining different coils as one RF channel with transmission lines. This concept not only simplifies the coil design but also achieves optimum isolation among all channels by overlapping. A 4-ch 8-loop knee coil at 1.5T was constructed to demonstrate this concept. The test result shows similar signal-to-noise ratio (SNR) at the center to a commercial 1.5T 15-channel Tx/Rx knee coil’s. Furthermore, additional acceleration at g factor 2 in SI direction is also achieved with a 4-ch only coil besides axial accelerations.
