Real-Time 3D Ultrasound Reconstruction Using Octrees

Real-Time GPU-Based 3D Ultrasound Reconstruction and Visualization

Ultrasound scanning is frequently used in medical practice because it is a noninvasive, safe and low-cost solution (vs. CT or MR). However, conventional ultrasound probes only provide 2D scans. 3D ultrasound reconstruction builds 2D scans into 3D volumes of the patient’s internals. Since these volumes can be used for acquiring out-of-angle views, 3D rendering of the anatomy, and for image guide...

Detection of Congenital Mullerian Anomalies Using Real-Time 3D Sonography

Real-time Collision Detection Using Spherical Octrees : Virtual Reality Application

A method for detecting potential collisions between three-dimensional moving objects is described in this paper. An object-centered, spherical octree representation is deened and implemented for the localisation of potentially colliding features between polyhedral objects. These features are subsequently tested for intersection in order to calculate precisely the actual collision points. Applic...

Real-time 3D computed tomographic reconstruction using commodity graphics hardware.

The recent emergence of various types of flat-panel x-ray detectors and C-arm gantries now enables the construction of novel imaging platforms for a wide variety of clinical applications. Many of these applications require interactive 3D image generation, which cannot be satisfied with inexpensive PC-based solutions using the CPU. We present a solution based on commodity graphics hardware (GPUs...

Faster 3d vocal tract real-time MRI using constrained reconstruction

Real-time magnetic resonance imaging (rtMRI) is a valuable emerging tool for studying the dynamics of vocal production. Conventional 2D rtMRI typically images the midsagittal plane of the vocal tract, acquiring data from all the important articulators. Dynamic 3D MRI would be a major advance, as it would provide 3D visualization of the vocal tract shaping dynamics, especially for the modeling o...
