An Improved Adaptive Ray Casting Algorithm
Ray casting is frequently used as a means of rendering volume data. While this results in realistic images, the computational cost associated with ray casting is high. (Levoy 1990) has proposed a method of per...

Multiscale Medial analysis of medical images
The Multiscale Medial Axis is a means for detecting and representing object shape at multiple scales simultaneously. One of its key characteristics is that the scale used to measure object properties (and henc...

Surgical instrument guidance using synthesized anatomical structures
We present a new method of intraoperative, image-based surgical instrument guidance. The method has the potential to significantly improve visualization of intraoperative procedures that currently depend on fl...

Reconstruction of the intracerebral vasculature from MRA and a pair of projection views
Clinicians cannot easily visualize 3D intracerebral vascular anatomy in adequate detail. We present methods of creating a detailed, 3D vascular map from an MRA and a pair of x-ray angiograms. The MRA provides ...

3D/2D registration via skeletal near projective invariance in tubular objects
We present a method of 3D/2D image registration. The algorithm is based on the property of near projective invariance in tubular objects. The skeletons of tubular anatomical structures (e.g., intracerebral blo...

3D Graph Description of the Intracerebral Vasculature from Segmented MRA and Tests of Accuracy by Comparison with X-ray Angiograms
This paper describes largely automated methods of creating connected, 3D vascular trees from individual vessels segmented from magnetic resonance angiograms. Vessel segmentation is initiated by user-supplied s...

Chapter and Conference Paper
An Architecture for Simulating Needle-Based Surgical Procedures
Many surgical procedures use cannulas, guidewires, and catheters in the treatment of life threatening conditions (e.g. cardiac tamponade and tension pneumothorax), or for diagnosis (e.g. diagnostic peritoneal ...

The Evaluation of the Color Blending Function for the Texture Generation from Photographs
Mass-casualty triage simulation requires the realistic depiction of wounds and other signs of external injury on victims. Texture maps permit images of actual wounds to be rendered over computer models. Severa...

A Study on the Perception of Haptics in Surgical Simulation
Physically accurate modeling of human soft-tissue is an active research area in surgical simulation. The challenge is compounded by the need for real-time feedback. A good understanding of human haptic interac...

Multiagent-Based Multi-team Formation Control for Mobile Robots
In the field of formation control, researchers generally control multiple robots in only one team, and little research focuses on multi-team formation control. In this paper, we propose an architecture, called V...
