Abstract
A system and method for directing an MRI system to form echo signals from spins in a volume-of-interest (VOI) includes creating an integrated pulse sequence that integrates a volume navigator pulse sequence with an imaging pulse sequence by coordinating a navigator TR with an imaging TR to preserve a steady state of magnetization in the VOI associated with the imaging pulse sequence. The integrated pulse sequence includes performing the imaging pulse sequence to acquire imaging data from the VOI, performing the navigator pulse sequence to acquire navigator data VOI, processing the navigator data to generate motion estimates of motion in the VOI, creating an updated imaging pulse sequence that prospectively corrects for the motion in the VOI using the motion estimates, and repeating these steps using the updated imaging pulse sequence.
