We have previously reported the development of a prototype 128 channel receive coil and MR system for cardiac MR at 3T. Here we describe further optimization of the system and its supported sequences, in particular balanced SSFP. We demonstrate the feasibility of high quality 2D multi-slice whole-heart cine imaging with acceleration factors of upto 6 in a single breath-hold using the 128 channel receive coil.
