Real-Time 3D Visualization of the Heart

چکیده
Introduction: Cardiac procedures, such as atrial fibrillation (AF) therapy, are limited by a lack of guidance visualization. This leads to difficulty in performing the treatment with accuracy and efficiency, which results in lengthy procedure times in excess of 3 hrs. Currently, visualization tools used in AF include 3D modeling of the patient's heart prior to the therapy or real-time 2D fluoroscopy. These approaches do not give immediate real-time visual feedback or provide the amount of information available in MR (e.g. electric current, blood flow). We focus on improving the procedure through 3D MR visualization [1-2]. For proper guidance, we allow the user to switch between a high frame rate (~45 fps) 2D acquisition [3] and a slower depth-informative 3D scan. We present a practical solution to improve AF therapy through real-time 3D visual feedback.

Enabling 3D Ultrasound Procedure Guidance through Enhanced Visualization
Real-time 3D ultrasound (3DUS) imaging offers improved spatial orientation information relative to 2D ultrasound. However, in order to improve its efficacy in guiding minimally invasive intra-cardiac procedures where realtime visual feedback of an instrument tip location is crucial, 3DUS volume visualization alone is inadequate. This paper presents a set of enhanced visualization functionalitie...
