The NPAC/OLDA Visible Human Viewer has been updated to version 2.0 as of December 1997.

Programming for version 2 was by Karlie Hutchens, with design by Paul Coddington and Karlie Hutchens. This work was supported by the On-Line Data Archives project, which is co-hosted by the Research Data Networks (RDN) and Advanced Computing Systems (ACSys) Co-operative Research Centres (CRCs). The work was done by the Distributed and High-Performance Computing Group in the Department of Computer Science at the University of Adelaide.

The original applet (version 1) was programmed by Michael Chang, and designed by Paul Coddington and Michael Chang. This work was supported by the Northeast Parallel Architectures Center at Syracuse University.

Processing of the images was by Paul Coddington and Michael Chang.

The following changes and additions have been made to the Visible Human Viewer in version 2.0:

• Added Visible Woman images from the Visible Human Project of the U.S. National Library of Medicine. The raw Visible Woman data has higher resolution than the Visible Man in the vertical direction (1/3mm slices rather than 1mm), however in this implementation of the viewer we have used the same resolution as for the Visible Man. This may be changed in the future (if we have more time and disk space!).

• Added MRI and CT images (these are not yet available, but may be added in the future).

• Added the capability to select a smaller region to be cropped out of the image before it is downloaded, which allows much faster downloading of high resolution sagittal and coronal images for a specific area of interest such as the head or chest. The region is selected by clicking and dragging the mouse over the desired area of the preview image.

• Modified the user interface to incorporate these extra features, and to make it more intuitive. Also made the applet shorter and wider, for easier use on smaller (640x480) monitors, by placing the buttons to the side.

• Updated the User Guide.

• Created a new version of the applet for Java version 1.1. Since many Web browsers do not yet support this new version of Java, the applet is written so that it first tests for which version of Java is supported by the browser, and the correct version of the applet is then downloaded.

• Some MPEG videos of image slices have also been created.
