Contrast-enhanced continuously moving table angiography has been shown to be effective in maintaining the position of the scanner sweet spot with the dynamic flow of the contrast bolus in peripheral angiography. In this work we incorporate the use of a four-element surface coil along with the body coil in one continuous acquisition. The body coil is used for signal reception from the heart to the popliteal arteries, at which point the surface array is activated to image the popliteal trifurcation region with increased spatial resolution and SNR. Scans are completed in approximately 60 seconds.
