1. A method of imaging a patient for a heart valve implant procedure, comprising the steps of: positioning the patient relative to an articulated imaging apparatus to provide isocentric positioning of an aortic root of the patient's heart relative to the imaging apparatus; inducing rapid ventricular pacing in the patient; injecting a contrast agent into the patient during the rapid ventricular pacing state; imaging a region of the aortic root using the articulated imaging apparatus to obtain image data for constructing a three-dimensional image; and constructing a three dimensional image using data from the imaging step.
