To improve the limited coverage of Time-of-Flight (TOF) arteriography, this study addresses the combination of 2D axial TOF and Continuously Moving Table (CMT) acquisitions for imaging the peripheral arteries. Since arterial blood flow is very pulsatile in the periphery, inflow in acquired slices and thus blood signal intensity depends on the time point of acquisition within the cardiac cycle. To compensate for this artefact, a new CMT gradient echo sequence has been designed, that provides several arterial images per slice position respectively per cardiac cycle and is based on a view sharing principle. Background signal was suppressed via image subtraction.
