Research Abstract

X-ray angiograms are usually used for inspection of the blood vessels because of their high resolution. To provide a more quantitative analysis of the information contained in angiograms, methods to reconstruct 3-D image of blood vessels have been developed. Conventional methods using X-ray angiograms utilize the biplane measurement system or the stereo measurement system. However, the information provided by only a few projections is insufficient for reconstructing 3-D image of blood vessels. Furthermore, conventional methods require extensive user interaction. Therefore, it is very difficult to reconstruct an accurate 3-D image of blood vessels.
We develop a 3-D image processing system to reconstruct 3-D image of blood vessels using a high-speed X-ray rotational projection system. The measurement system, consisting of a cone beam X-ray source and an image intensifier (II), provides 512x512 projection images corresponding to 60 views of the blood vessel structure in a short measurement period (2 sec). The 3-D image processing method consists of correction of image distortion generated by II, estimation of the measurement system geometry, and 3-D image reconstruction of the blood vessels from short scan cone-beam projections. The 3-D reconstructed images can be visualized on a computer graphics, and are employed to fabricate a 3-D model of the blood vessel structure. From results of the application to the X-ray angiograms of patient blood vessels, we show that the proposed image processing system is effective for quantitative diagnosis and treatment planning.
