Three Dimension Reconstruction of Coronary Artery Tree Using Single-View Cineangiogram

Abstract

Problem statement: Whereas most of the conventional techniques propose using multiview cineangiograms to reconstruct 3D objects this article proposes to integrate a Three Dimension (3D) model of the coronary artery tree using a standard single-view cineangiogram. Splitting the cineangiograms into non-sequenced and different angle views is how the data is supplied in this method. Each single view can be used to reconstruct a robust 3D model of the coronary artery from that angle of view. Although the dynamic variations of blood vessels curvature have been difficult to study in Two Dimension (2D) angiograms, there is both experimental and clinical evidence showing that 3D coronary reconstruction is very useful for surgery planning and clinical study. Approach: The algorithm has three stages. The first stage is the vessel extraction and labeling for each view for the purpose of constructing the 3D model, while in the second stage, the vessels information (x, y and z) will be saved in a data file to be forwarded to the next stage. Finally, we input the x, y and z of a specific coronary artery tree to the OPENGL library included in the software, which we developed and called Fast 3D (F3D) and which is displayed in R 3 . Results: Experimental evaluation has been done to clinical raw data sets where the experimental results revealed that the proposed algorithm has a robust 3D output. Conclusion: Results showed that our proposed algorithm has high robustness for a variety of image resolutions and voxel anisotropy.

Voice Activation Visualization for Echocardiograph and 3d Angiographic Images in Surgery

“…Validation of this work involves three parts, where we validated the processed angiography images, validated processed echocardiography images and the voice activation itself. As mentioned in Hasan et al (2009) and Hussein et al (2011), results for these parts has been evaluated by medical specialist and they agree the both method had achieved good performance and succeeds in presenting legible illustration for various angiography and echocardiography images. Once the medical specialists agree with the processed angiography and echocardiography processed images, we trained them on how to use the complete system and distributed a brief questionnaire to validate user acceptance and any adding requirement from their counterpart.…”

“…To visualize this, we extracted the tree from angiographies using extension work of Lin and Ching (2005) and later we decided to apply the modified Hoover et al (2000) guided with Lin et al (2010) proposed technique. One the vessel extraction from angiographic was done, we are able to make the last step which is reconstructing the 3D shapes (Hasan et al, 2009), please refer to…”
