“…Image processing techniques have been helpful for retrospective registration, particularly for simpler motions. [21][22][23] An alternative approach may come from the development of a new generation of x-ray detectors capable of estimating the energy of each interacting x-ray photon. An exciting aspect of energy-resolved photon-counting (EPC) imaging is the potential to generate "DSA-like" images from a single exposure that are not susceptible to motion artifacts.…”

While the energy-based methods are not necessarily optimized and further improvements are likely, the linearized noise-propagation analysis provides the theoretical framework of a level playing field for optimization studies and comparison with conventional DSA. It is concluded that both dual-energy and photon-counting approaches have the potential to provide similar angiographic image quality to DSA.

“…6 Although many software tools have been developed to assist with image registration for in-plane translation and rotations, [6][7][8][9][10][11] uncooperative patients and involuntary motions (e.g., respiratory, swallowing and gas) remain the primary cause of poor image quality. [12][13][14] As a consequence, DSA remains largely unsuccessful for cardiac imaging 15 where nonsubtracted angiography requiring higher radiation exposures and iodine concentrations remains the standard.…”
