摘要
Techniques are provided for reconstructing cardiac frequency phenomena from a sequence of angiographic images, i.e., two-dimensional projection images acquired at faster than cardiac rate (greater than two-fold), and analyzed to provide a spatiotemporal reconstruction of moving vascular pulse waves according to that projection. In aspects, a cardiac frequency bandpass filter and/or a Eulerian magnification may be applied to the angiographic data to output the spatiotemporal reconstruction of cardiac frequency angiographic phenomena.
