Aim of this study was to combine CAIPIRINHA accelerated multi-slice imaging, with TrueFISP. However, due to the constraint to maintain the steady state, the implementation of CAIPIRINHA which enables the simultaneous acquisition of several slices, is only achievable by segmenting the acquisition rendering real-time applications impossible. With the presented new approach the steady state could be maintained without segmenting the acquisition by applying individual phase cycles to each slice. High quality images were reconstructed performing phantom experiments and real-time imaging of the human heart in two slices simultaneously.
