This brief overview relates to the recent introduction of real-time three-dimensional echocardiographic imaging techniques, which has revolutionized echocardiography, as images are obtained in just one beat. A great potential lies ahead as clinical applications are multiple. T H R E E D I M E N S I O N A L E C H O C A R D I O G R A P H Y In the past, routine clinical use of three-dimensional ec...

The study of sign languages provides a wide field of applications for computer vision systems, but the analysis of such gestures often leads to complex 3D reconstructions or to ambiguities. In this paper, we describe the architecture of an image analysis system that performs sign language analysis by using a prediction/verification approach. The system integrates a model of the sign language’s ...

UNLABELLED Introduction Echocardiography is the diagnostic test of choice for latent rheumatic heart disease. The utility of echocardiography for large-scale screening is limited by high cost, complex diagnostic protocols, and time to acquire multiple images. We evaluated the performance of a brief hand-held echocardiography protocol and computer-assisted auscultation in detecting latent rheuma...

INTRODUCTION M-mode echocardiography estimates of the left ventricular mass (LVM) were greater than magnetic resonance imaging (MRI) estimates. There are substantial differences between the methods both in the means of measuring and the calculation formula. The aim of this study was to investigate whether any difference in estimates of LVM between M-mode echocardiography and MRI is due to the m...

The year 2013 marked the 60th anniversary of Inge Edler and Hellmuth Hertz's discovery of echocardiography and the 160th anniversary of the death of Christian Andreas Doppler (1803–1853). The work of these pioneers marked modern cardiology not only by providing a more accurate diagnosis of heart disease but also by guiding patients' management. Echocardiography has to be included among the top ...

Contrasted with other information carriers, such as speech and text, images contains larger amount of information, especially in sequential images, that is waiting to be exploited, in particular the dynamic information of correlation, difference, and temporal relationship between different frames. This dynamic information contributes a great deal in analysis of 4D images. This paper proposes a ...

uring the last several years, dramatic developD ments have taken place in the area of cardiac imaging techniques. From an era of imaging by silhouettes (chest roentgenography, fluoroscopy, angiocardiography, angiography), we have emerged into an era of imaging by tomographic scanning (echocardiography, radionuclide and computed tomography, magnetic resonance).l-3 Two-dimensional intravascular e...

BACKGROUND Standardized training via simulation as an educational adjunct may lead to a more rapid and complete skill achievement. The authors hypothesized that simulation training will also enhance performance in transesophageal echocardiography image acquisition among anesthesia residents. METHODS A total of 42 clinical anesthesia residents were randomized to one of two groups: a control gr...

The recognition of people orientation in single images is still an open issue in several real cases, when the image resolution is poor, body parts cannot be distinguished and localized or motion cannot be exploited. However, the estimation of a person orientation, even an approximated one, could be very useful to improve people tracking and re-identification systems, or to provide a coarse alig...

The implementation of a Structure-from-Motion (SfM) pipeline from a synthetically generated scene as well as the investigation of the faithfulness of diverse reconstructions is the subject of this project. A series of different SfM reconstructions are implemented and their camera pose estimations are being contrasted with their respective ground truth locations. Finally, injection of ground tru...
