1. A system for acquiring images of three-dimensional flow within an interior volume of a subject, the system comprising:
an x-ray imaging system configured to acquire images from the subject; and
a computer system configured to:
control the x-ray imaging system to perform a single sweep of the subject to acquire a single-sweep, three-dimensional (3D) image dataset;
reconstruct the single-sweep, 3D image dataset into a 3D image volume;
determine a phase shift corresponding to pulsatile contrast in the vessels within the 3D image volume;
quantify a flow through the vessels within the 3D image volume using the phase shift; and
generate a report including quantified flow through the vessels within the 3D image volume.
