The HeartSweep tool for cardiac imaging is a feature of the Artis one angiography system (Siemens Healthcare). With HeartSweep, users do not need to obtain multiple acquisitions from different projections. 
These four images (Figures 1-4) depict a 15-frames-per-second acquisition of the left coronary arteries utilizing an injection of 10ccs of contrast. The customized elliptical orbit allows continuous image projections at multiple C-arm angulations during one five-second sweep around the heart.
