Abstract: The present disclosure relates to a method for vascular imaging and determining dynamic vascular parameters of blood flow. According to an embodiment, the present disclosure relates to an apparatus and method of determining dynamic vascular parameters of blood flow, comprising acquiring two-dimensional projection images of a vascular region of interest at a predetermined frequency, the vascular region of interest being downstream of a site of vascular administration of a radio-opaque medium, identifying, within the acquired two-dimensional projection images, heterogeneities of the radio-opaque medium, and determining the dynamic vascular parameters of the blood flow based on spatial movements of the identified heterogeneities of the radio-opaque medium. In an embodiment, the predetermined frequency is greater than 100 Hz.
