Claim 14:
15. A system configured to reconstruct multiple phases of a vasculature of a subject, comprising:
a pump to inject a contrast agent into the vasculature of the subject at a selected injection start time, wherein the contrast agent injected into the subject has a x-ray scattering pattern different than that of an anatomy of the subject;
an imaging system including:
a x-ray source;
a detector to detect x-rays emitted by the x-ray source and generate an image data;
a gantry configured to enclose both the x-ray source and the detector and in which both the x-ray source and the detector are configured to move, wherein the gantry is further configured to encircle the subject;
a first power source to power the x-ray source at a first power to emit x-rays to be detected by the detector at a selected imaging first time; and
a second power source to power the x-ray source at a second power to emit x-rays to be detected by the detector at a selected imaging second time;
wherein the second power source has a voltage that is about 40 kV to about 60 kV different than the first power source and an amperage that is about 20 mA to about 150 mA different than the first power source;

a controller in communication with the imaging system and the pump operable to provide the imaging system instruction to the imaging system and the pump instruction to the pump to control initiation and timing of the injection of the contrast agent into the subject and to acquire the image data based upon the initiation and timing of the injection of the contrast agent and a path;
wherein the x-ray source and the detector are configured to move in a selected path relative to the subject based on the imaging system instruction; and
wherein the image data is of a selected portion of the subject over an imaging period of time and is acquired while (i) moving the x-ray source and the detector along the path and (ii) switching between powering the x-ray source at the first power to emit x-rays to be detected by the detector and powering the x-ray source at the second power to emit x-rays to be detected by the detector, wherein the image data includes a plurality of image frames of the subject acquired over the imaging period of time at both (i) different positions relative to the subject based on the moving of the x-ray source and the detector and (ii) different powers; and
an image data indexer configured to (i) receive inputs from a user regarding parameters of a first anatomical phase and a second anatomical phase from the user related to a region of interest of the subject and (ii) index the plurality of image frames of the subject based at least on a time stamp by the controller and execute instructions to determine whether a selected portion of the image data is regarding the first anatomical phase or the second anatomical phase based on at least the plurality of image frames of the subject and the received inputs;
wherein the image data indexer comprises a processor system configured to, based on the region of interest, determine a first sub-plurality of image frames of the plurality of image frames that relate to the first anatomical phase and a second sub-plurality of image frames of the plurality of image frames that relate to the second anatomical phase.
