Level set method has been widely used in medical image analysis, but it has difficulties when being used in the segmentation of left ventricular (LV) boundaries on echocardiography images because the boundaries are not very distinguish, and the signal-to-noise ratio of echocardiography images is not very high. In this paper, we introduce the Active Shape Model (ASM) into the traditional level s...

Recently, many interventional centres have adopted intracardiac echocardiography (ICE) in preference to transoesophageal echocardiography to guide percutaneous patent foramen ovale (PFO) closure. ICE obviates the need for general anaesthesia, facilitating earlier hospital discharge, and gives superior imaging capability, particularly of the inferior interatrial septum. 2 The advent of real-time...

PURPOSE OF REVIEW To review the utility and the latest developments in three-dimensional (3D) echocardiography of mitral valve prolapse. RECENT FINDINGS Although 3D echocardiography was invented in 1974, it did not gain wide clinical acceptance until the introduction of real-time 3D echocardiography in the first decade of the 21st century. Driven by improvements in probe technology and increa...

3D reconstructions allow cultural institutions such as museums and historic sites a tool to vividly illustrate the past while educating the public about competing interpretations of history and change over time. 3D technology also offers many practical benefits including low cost, flexibility, and the potential for collaboration. This paper presents potential applications of 3D reconstructions ...

Medical imaging is inserting a significant role in diagnosis the diseases and in image guided surgery. There are varied imaging modalities for various applications giving the anatomical and physiological conditions of the patient. Noise suppression of echocardiography images may be a difficult issue for correct and effective human interpretation and computer-assisted analysis. In spite of compr...

L'echocardiographie trouve de plus en plus une place importante dans L'evaluation des di­verses cardiopathies tant acquises que Congeni­tales. Cette technique, non sanglante et atrau­matique a surtout l'intcrrct de Pouvoir etre re­pete a volonte.  Ainsi l'echoc'.lrdiographie rend de servic-:: certains dans L'etablissement du bilan preopera­toin: des cctrdiooathies valvulaires sifrequente en Ir...

In 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 ...
