Summary

An attempt at infrared photography of the human gastric mucosa was made using the Olympus fiberoptic gastrocamera type S2 (GTF-S2) and Kodak Ektachrome Infrared Film (IE Film) (4).

By critical selection of the illumination balance with No. 12 and doubled CC50C-2 of Kodak Wratten Filters (3), vessel patterns of the mucosa and deeper layers were photographed in orange and dark blue respectively; these patterns were invisible to the naked eye, and were also not recorded by an ordinary gastrocamera.

Key words:

Infrared gastrocamera - Infrared photography
