A method using double navigators, real time slice tracking and registration, and a real time PAWS gating algorithm was developed for a double inversion black blood 2D fast spin echo sequence. Compared to the previous single navigator method, the double navigator method reduced image artifacts due to the respiration induced misregistration between selective inversion location and image location, allowing high quality free-breathing black blood cardiac imaging.
