A radiographic imaging apparatus and method for vascular interventions for acquiring very high resolution radiographic images over a small region of interest (ROI). The apparatus and associated method employs digital solid state x-ray image detectors for the medical imaging application of angiography. A mechanical arrangement, for example an arm attached to an existing large area x-ray detector, allows the small area ROI digital detector to be temporarily positioned over a region located by the standard large area imager so that additional very high resolution digital images may be obtained over the ROI. |
