National Library of Medicine Visible Human Project.

The initial aim of the Visible Human Project is to create a digital image data set of a complete human male and female cadaver in MRI, CT and anatomical modes.

The imaging of the male cadaver has been completed. The data set consists of axial MRI images of the head and neck taken at 5 mm intervals and longitudinal sections of the rest of the body also at 5 mm intervals. The MRI images are 256 pixel by 256 pixel resolution. Each pixel has 12 bits of grey tone resolution.

The CT data consists of axial CT scans of the head and neck taken at 1 mm intervals at a resolution of 512 pixels by 512 pixels where each pixel is made up of 12 bits of grey tone. The axial anatomical images are 2048 pixels by 1216 pixels where each pixel is defined by 24 bits of color, about 7.5 megabytes. The anatomical cross-sections are at 1 mm intervals and coincide with the CT axial images. About 1880 cross-sections were obtained from the male cadaver for each mode, i.e., CT and anatomy. The male Visible Human Data Set will be available via FTP on the Internet and via DAT tape in October -94. FTP is free. There will be a duplication fee for the DAT tape. The fee is expected to be under $1,000. The size of the data set is expected to be about 15 gigabytes.

A licensing agreement with NLM will be required in order for you to gain access to the data set. This is a non-financial agreement which states that neither NLM nor the government has any financial interest in your product. We want to know who you are and what you propose to do with the data set. We want you to agree to protect the integrity of the data set and to credit NLM and the Visible Human Project as the source of the pictures in any derived product. We would like a copy of any derived product. And we would like you to help us by critiquing our work so that if NLM continues to produce further anatomical data sets, we can correct, in those data sets, any deficiencies which may be present in the current data set. Your e-mail address is being added to a mailing list of people interested in receiving the licensing agreement. The agreement should become available towards the end of August or early in September.

The data set from the female cadaver will have the same characteristics as the male cadaver with one exception. The axial anatomical images will be obtained at 0.33 mm intervals instead of 1.0 mm intervals. This will result in over 5,000 anatomical images. The data set is expected to be about 40 gigabytes in size. Distribution is anticipated during the Summer of 1995. We are decreasing the spacing in the "Z" direction to 0.33 mm in order to match the pixel spacing in the "XY" plane which is 0.33 mm. This will enable developers who are interested in three-dimensional reconstructions to work with cubic voxels.

If you have further questions, please don't hesitate to ask. Your interest in NLM's Visible Human Project is greatly appreciated.

MRI image sets.

Image sets of a brain map on Japanese monkey by using MRI which were created by Dr.Masato Taira of Department of Physiology, Nihon University, School of Medicine are available. These image set were anatomically correct. Please use them for a research on physiology or medical image processing. ftp://ftp.nc.nihon-u.ac.jp/pub/data/MRIMonkeyHead


3D datasets

Avalon was created to be a 3D object "repository" for the net. You'll find 3D datasets in various formats, utilities to convert between the different formats, and documents explaining the file formats. There is a /pub/incoming directory for uploads, so if you have anything to contribute, please upload it! If you have any problems connecting to avalon, try its mirror site Kubota Pacific at (144.52.120.9) ftp://ftp.kpc.com/pub/mirror/avalon.
