SYSTEM AND METHOD FOR CORRECTING FLOW VELOCITY MEASUREMENTS IN PHASE CONTRAST IMAGING USING MAGNETIC FIELD MONITORING |
摘要 |
A system and method of phase contrast imaging includes a system control programmed to acquire a first set of data and a second set of data via the RF coil assembly during a scan and acquire a third set of data and a fourth set of data via the plurality of magnetic field monitoring devices during the scan. A first single data set from the first and third sets of data is formed, and a second single data set from the second and fourth sets of data is formed. The system control is also programmed to reconstruct a phase contrast image based on the first and second single data sets to correct for spatially-dependent background phase variations.
