Abstract
Displacement values which indicate respiration phase are acquired along with each view of an NMR scan. Two or more such NMR scans are conducted and the deviation of each displacement value from a smooth reference curve is employed to measure the integrity of its associated NMR image data. The NMR image data from the separate scans are combined to reduce random noise and motion artifacts, and the combination is accomplished by weighting the data in accordance with its measured integrity.
