Abstract: A method for obtaining perfusion data includes providing an object of interest, estimating a first quantity of contrast agent utilized by a mono-energy computed tomography (CT) imaging system to image the object of interest, introducing a second quantity of contrast agent into the object of interest, the second quantity of contrast agent less than the first quantity of contrast agent, and scanning the object of interest using a multi-energy Computed Tomography (MECT) system to acquire data.

Abstract: A system and method of acquiring x-ray data, comprising: acquiring a series of x-ray data for generating at least one x-ray image using an x-ray detector to receive x-ray beams from an x-ray source, wherein an object being imaged is displaced along an axis, the axis extending perpendicularly through a plane defined by the x-ray beams, wherein the displacement occurs at, at least one of a constant, accelerating, and decelerating rates; varying the rate of displacement thus enabling the x-ray detector to acquire data for at least one x-ray image during accelerating or decelerating displacement; and employing current modulation.
