Abstract: An angiogram is a study of blood vessels where an angiographic chemical contrast agent is injected while a sequence of images (typically x-rays) are obtained. The contrast pattern on the sequence of images provides information about the vascular anatomy and physiology.

In this invention, the organization of cardiac frequency magnitude and phase enables equivalent information on anatomy and physiology to be obtained with less dose of injected chemical contrast agent, less x-ray dose, and/or less navigation of the injecting catheter within blood vessels.
