Gc. Ribas et al., Anaglyphic three-dimensional stereoscopic printing: revival of an old method for anatomical and surgical teaching and reporting - Technical note, J NEUROSURG, 95(6), 2001, pp. 1057-1066
The authors describe how to use the three-dimensional (3D) anaglyphic metho
d to produce stereoscopic prints for anatomical and surgical teaching and r
eports preparation by using currently available nonprofessional photographi
c and computer methods.
As with any other method of producing stereoscopic images, the anaglyphic p
rocedure is based on the superimposition of two slightly different images o
f the object to be reproduced, one seen more from a left-sided point of vie
w and the other seen more from a right-sided point of view. The pictures ar
e obtained using a single camera, which following the first shot can be sli
d along a special bar for the second shot, or by using two cameras affixed
to a surgical microscope. After the images have been distinguished from eac
h other by applying different complementary color dyes, the images are scan
ned and superimposed on each other with the aid of nonprofessional imaging-
manipulation software used on a standard personal computer (PC), and are pr
inted using a standard printer. To be seen stereoscopically, glasses with c
olored lenses, normally one red and one blue, have to be used.
Stereoscopic 3D anaglyphic prints can be produced using standard photograph
ic and PC equipment; after some training, the prints can be easily reproduc
ed without significant cost and area particularly helpful to disclose the 3
D character of anatomical structures.
