Real-time three-dimensional (3-D) echocardiography is a new imaging modality that presents the unique opportunity to visualize the complex 3-D shape and motion of the left ventricle (LV) in vivo and to measure the associated global and local function

The accuracy of mutual information-based registration for automatic alignment of planning CT and daily 3D ultrasound images is evaluated. The results show the importance of preprocessing both the CT and the daily 3D ultrasound images to maximize regi

Stress echocardiography is a routinely used clinical procedure to diagnose cardiac dysfunction by comparing wall motion information in prestress and poststress ultrasound images. Incomplete data, complicated imaging protocols and misaligned prestress

Stress echocardiography is a routinely used clinical procedure for diagnosing myocardial ischemia. In this procedure, images of the left ventricle are acquired both at rest and upon stress; these are then compared to detect the onset of new wall moti

A generalized, accurate, automatic, retrospective method of image registration for three-dimensional images has been developed. The method is based on mutual information, a specific measure of voxel similarity, and is applicable to a wide range of im

We investigated the registration of ultrasound volumes based on the mutual information measure, a technique originally applied to multimodality registration of brain images. A prerequisite for successful registration is a smooth, quasi-convex mutual

Current intravascular ultrasound (IVUS) techniques of tissue characterization are morphology based, a characterization based on surface echogenicity and spectral parameters from the fundamental imaging alone. Complex harmonic signals develop as a res

Ultrasound imaging is commonly used for emergency diagnosis of blunt trauma. Portable scanners are able to provide adequate imaging in remote and dangerous areas; however, medical expertise may not be available in the immediate local area to interpre

Purpose: We report a deformable model (DM)-based fully automatic segmentation of the left ventricular (LV) myocardium (endocardium + epicardium) in real-time three-dimensional (3D) echocardiography. Methods: Initialization of the DM is performed thro
