1. A method for stent viewing in medical imaging, the method comprising: identifying from a plurality of frames of data a first sub-set of frames of data representing contrast agents, the frames of data representing a patient at different times during inflow of the contrast agent such that the first sub-set the frames of data represent the contrast agent and a second sub-set of the frames of data are free of contrast agent; detecting markers for a stent in at least some of the frames of data; selecting a reference contrast frame of data from the first sub-set of the frames of data, the reference contrast frame of data selected as a function of detected markers for the stent; detecting a vessel wall in the reference contrast frame of data; aligning the reference contrast frame of data with a stent output; and outputting an image representing the stent, the image including a highlight of the vessel wall, the highlight aligned with the stent based on the aligning.
