Accuracy of distance measurements in biplane angiography
Distance measurements of the vascular system of the brain can be derived from biplanar digital subtraction angiography (2pDSA). The measurements are used for planning of minimal invasive surgical procedures. Our 90°-fixed-angle G-ring angiography system has the potential of acquiring pairs of such images with high geometric accuracy. The sizes of vessels and aneurysms are estimated applying a f...
متن کاملStereoscopic magnification in spinal angiography.
This technique combines the advantages of magnification and stereoscopic angiography. A heavy-duty x-ray tube oscillating between two positions (25 mm apart) allows serial spinal angiograms to be produced in stereo magnification (factor 2.0) using the 0.2 mm, 12 kW focal spot. The x-ray tube can be rapidly changed for normal serial angiography with a 0.6 mm, 50 kW focus. The technique is easy t...

ii I would like to dedicate my thesis to my Parents, Professors, Relatives and Friends, every single being who have helped me and encouraged at every stage of my life. iii ACKNOWLEDGMENTS I am very grateful to my academic advisor, Dr. Madhavan Raghavan, who gave me an opportunity to be a part of his wonderful team at BioMOST laboratory, University of Iowa. I really appreciate his help, guidance...
متن کاملStereoscopic digital subtraction angiography in neuroradiologic assessment.
Digital subtraction angiography (DSA) with stereoscopic imaging was performed in 40 patients for evaluation of a variety of cerebrospinal disorders. It was facilitated by a C-arm mounted x-ray tube and imaging chain with 7 degrees angulation between image pairs. Stereoscopic digital imaging proved particularly useful in the preoperative assessment of aneurysms, arteriovenous malformations, and ...
متن کامل3D Reconstruction of Coronary Artery using Biplane Angiography
In this paper, we present a new method for the 3D reconstruction and visualization of coronary arteries in biplane angiography. The proposed method performs direct reconstruction of 3D coronary artery pathways without computing the 2D or 3D vessel centerlines. A front propagation algorithm is used to reconstruct the coronary artery pathways in 3D space. Starting from one or more 3D points, the ...
