3-D reconstruction of coronary arterial tree to optimize angiographic visualization
A patient-specific 3-D coronary tree model can be utilized for planning optimal clinical views: minimal overlap and foreshortening can be optimized in both interventional cases and studies. Expand

Objective: To evaluate the clinical utility of images acquired from rotational coronary angiographic (RA) acquisitions compared to standard “fixed” coronary angiography (SA). Background: RA is a… Expand
In vivo 3D modeling of the femoropopliteal artery in human subjects based on x-ray angiography: methodology and validation.
Endovascular revascularization of the femoropopliteal (FP) artery has been limited by high rates of restenosis and stent fracture. The unique physical forces that are applied to the FP artery during… Expand
Kinematic and deformation analysis of 4-D coronary arterial trees reconstructed from cine angiograms
A new method has been developed for reconstruction and analysis of these patient-specific 4-D datasets utilizing routine cine angiograms. Expand
Coronary angiography: the need for improvement and the barriers to adoption of new technology.
Traditional coronary angiography presents a variety of limitations related to image acquisition, content, interpretation, and patient safety. These limitations were first apparent with coronary… Expand

A new technique is proposed to describe: (1) the curvilinear nature of 3-D coronary arteries and intracoronary devices; (2) the magnitude of the arterial deformation caused by intracornary devices and due to heart motion; and (3) optimal view(s) with respect to the desired "pathway" for delivering intracortical devices.

Impact of Three Dimensional In-Room Imaging (3DCA) in the Facilitation of Percutaneous Coronary Interventions
Introduction: Coronary angiography is a two-dimensional (2D) imaging modality and thus is limited in its ability to represent complex three-dimensional (3D) vascular anatomy. Lesion length,… Expand

Poor bioavailability, rapid degradation, antigenicity, and high cost often limit the use of proteinaceous pharmaceuticals. One goal of structural biochemistry is the reduction of complex molecules to… Expand
Initial clinical experience of selective coronary angiography using one prolonged injection and a 180° rotational trajectory
Evaluate the safety of prolonged coronary injections during a rotational acquisition covering 180°.
