THE VISIBLE HUMAN
: a complete, anatomically detailed, three-dimensional scan of the male and female human body. How was this done?
The male cadaver was frozen in gelatin and cut horizontally at 1 mm intervals into 1,871 slices and photographed to give 65 GB of high resolution images. The female was cut at 0.3 mm intervals resulting in ~40 GB of data. In addition, the bodies were scanned by CT (computer assisted tomography) and MRI (magnetic resonance imaging). If that wasn’t macabre enough:
Both bodies were donated to science but because the donors did not know their specific use and the male died by lethal injection, ethical issues have been raised. Also, these are not perfect bodies. The male lacks one testicle. The female shows signs of cardiovascular disease. Art and Anatomy:
Artist Lisa Nilsson was inspired by the images to create painstakingly realistic replicas with rolled up paper, an art form known as quilling
. Her artwork takes weeks to create and sells for up to $7,000.
