Images from Digital Humans CD-ROM
The Digital Humans CD-ROM documents the digitization of male and female cadavers by the Visible Human Project. When the Visible Human datasets were released to the public a decade ago, I developed programs for segmenting and reconstructing 3D models using voxel-based computer graphics techniques. It's my intention to put into the public domain the full content of the CD-ROM, including a series of videos showing the actual ...

Brain-Computer Interface
BCI: Research allowing direct communication between the computer and the human mind. A Brain-Computer interface could be used to control prosthetic devices, significantly enhancing the quality of life for handicapped individuals. The NIH has formed the Neural Prosthesis Program, which holds yearly workshops and funds some of the research.
BCI research is proceeding ...

Segmentation and Visualization for the Digital Humans CD-ROM
This abstract was presented at the First International Visible Human Project Conference in 1996. The webified slides are available here.
INTRODUCTION
The Digital Humans CD-ROM is a multimedia exploration of the Visible Human Project intended for the general public. An important part of the CD-ROM was a variety of 3D anatomy reconstructions using both the cryosection and computerized tomography (CT) cross-sectional images. This abstract describes the basic process ...

Interactive Visualization of Three-Dimensional Segmented Images for Neurosurgery (follow link for PDF version)
Technical Paper—June 1995
William T. Katz, Ph.D., M.D.
John W. Snell, Ph.D.
Ken Hinckley, M.S.
Visualization for neurosurgical applications requires speed, realism, and methods for unobtrusive and intuitive interactive exploration. The method presented here uses fast voxel projection to multiple compositing buffers together with a hybrid user interface which includes ...
