Research ArticleOpen accessIn the author namesMeasurements of Mitral Annular Displacement in 2D Echocardiography ImagesFaten A. Dawood, Rahmita W. Rahmat, Suhaini B. Kadiman et al.Mitral Annular Displacement (MAD) in echocardiography has been described as a variation in mitral annulus position between the end-diastolic and the end-systolic in a complete cardiac cycle. It could be used as a rapid and reproducible method of determining the LV global systolic function and could be an easily detectable index for wall motion abnormalities. In this study, a computational … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 4 Jul 2015 · 6,853 accessesView PDF Cite

Research ArticleOpen accessIn the author namesCAVITY SEGMENTATION AND STROKE VOLUME MEASUREMENT METHODS FROM ECHOCARDIOGRAPHIC IMAGES: REVIEWAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.The complexity and criticality of heart disease diagnosis and treatment have frequently attracted the attention of researchers to develop approaches that can handle accurate clinical assessments. One of these complexities is measuring the Right Ventricle stroke volume. Therefore, different cardiac imaging techniques have been developed to help specialists in their regular clinical work and in the operating theatre to assist … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,416 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAutomatic Detection of the End-Diastolic and End-Systolic from 4D Echocardiographic ImagesAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.Accurate detection of the End-Diastolic (ED) and End-Systolic (ES) frames of a cardiac cycle are significant factors that may affect the accuracy of abnormality assessment of a ventricle. This process is a routine step of the ventricle assessment procedure as most of the time in clinical reports many parameters are measured in these two frames to help in diagnosing and … …Journal of Computer Science, Vol. 11, Issue 1 · 25 Aug 2014 · 8,506 accessesView PDF Cite

Research ArticleOpen accessIn the author namesVoice Activation Visualization for Echocardiograph and 3D Angiographic Images in SurgeryRahmita W. Rahmat, Mohd Z. Dimon, Zinah R. Hussein, Hasan H. KhalilIn some cases, surgeons need to navigate through the computer system for reconfirmation patients’ details and unfortunately surgeons unable to manage both computer system and operation at the same time. In this paper we propose a solution for this problem especially designed for heart surgeon, by introducing voice activation system with 3D visualization of Angiographic images, 2D visualization of Echocardiography … …Journal of Computer Science, Vol. 8, Issue 11 · 9 Oct 2012 · 8,304 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAutomatic Boundary Detection of Wall Motion in Two-dimensional Echocardiography ImagesFaten Abed Ali Dawood, Rahmita Wirza Rahmat, Mohd Zamrin Dimon et al.Problem statement: Medical image analysis is a particularly difficult problem because the inherent characteristics of these images, including low contrast, speckle noise, signal dropouts and complex anatomical structures. An accurate analysis of wall motion in Two-dimensional echocardiography images is “important clinical diagnosis parameter for many cardiovascular diseases”. A challenge most researchers faced is how to speed up the clinical decisions … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 8,192 accessesView PDF Cite

Research ArticleOpen accessIn the author namesThree-Dimension Coronary Artery Tree Curvature ConfirmationHassan H. Khalil, Rahmita O.K. Rahmat, D. M. Zamrin et al.Problem statement: Three-Dimension (3D) reconstruction is one of the vital and robust tools that provide aid in many fields, especially medicine. This article is about 3D shape similarity and it presents a comparison approach between principal curvature methods of 3D output. Our approach follows the concept of using the gray scale value as the z dimension and the other approach … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,771 accessesView PDF Cite

Research ArticleOpen accessIn the author namesThree Dimension Reconstruction of Coronary Artery Tree Using Single-View CineangiogramHassan H. Khalil, Rahmita O.K. Rahmat, D. M. Zamrin et al.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 … …Journal of Computer Science, Vol. 6, Issue 12 · 22 Nov 2010 · 8,031 accessesView PDF Cite
