3D CTA 2D XA METHOD FOR AUTOMATIC ANALYSIS OF VASCULAR STRUCTURES IN 2D XA IMAGES USING 3D CTA IMAGES RECORDING MEDIUM AND DEVICE FOR PERFORMING THE METHOD

摘要

The automatic vascular structure analysis method using the 3D CTA image information is performed by performing the rigid body matching on the blood vessels of the 2D XA (X-ray Angiogram) image and the 3D CTA (Computed Tomography Angiography) image of the same subject; Generating respective blood vessel graph structures for blood vessels of the 2D XA image and the 3D CTA image; Comparing a blood vessel graph structure of the blood vessel of the 2D XA image with a blood vessel graph structure of the 3D CTA image to set a region of interest in the blood vessel of the 2D XA image; And interpreting the ROI using the 3D CTA image information. Therefore, it is possible to improve the accuracy of the vascular structure analysis in the 2D XA image by comparing the similarity using the 3D CTA image information, and it is possible to perform the accurate operation using the same.;
