We investigated simultaneous multi-slice as a method for performing respiratory-gating. One slice is used to monitor respiration, while another slice is targeted for imaging. Radial CAIPI data was acquired using a golden angle ordering for free-breathing 2D cine. At each cardiac phase and at each heart-beat, images of the heart and the diaphragm were obtained. Finally, a composite image of the heart was reconstructed using data from all frames acquired at end-expiration, with more projections and higher quality than a single heart-beat image.
