Data
The male cadaver was encased and frozen in a gelatin and water mixture in order to stabilize the specimen for cutting. The specimen was then “cut” in the axial plane at 1 millimeter intervals. Each of the resulting 1,871 “slices” were photographed in both analog and digital, yielding 15 gigabytes of data. In 2000, the photos were rescanned at a higher resolution, yielding more than 65 gigabytes. The female cadaver was cut into slices at .33 millimeter intervals, resulting in some 40 gigabytes of data.
The term “cut” is a bit of a misnomer, yet it is used to describe the process of grinding away the top surface of a specimen at regular intervals. The term “slice,” also a misnomer, refers to the revealed surface of the specimen to be photographed; the process of grinding the surface away is entirely destructive to the specimen and leaves no usable or preservable “slice” of the cadaver.
The data is supplemented by axial sections of the whole body obtained by computed tomography, axial sections of the head and neck obtained by magnetic resonance imaging, and coronal sections of the rest of the body also obtained by magnetic resonance imaging.
The scanning, slicing and photographing took place at the University of Colorado's Health Sciences Center, where additional cutting of anatomical specimens continues to take place.

Famous quotes containing the word data:
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
