A System is presented that demonstrates a fully digital transmit and receive system for multislice EPI acceleration. The transmit system is based on a TI DAC5688 chip, which provides superior tailored pulse generation with almost two orders of magnitude lower spurious inter-modulated frequencies. A 32 channel coil is used to measure the 4-slice separation of simultaneous axial slice excitation.
