Computer models and images of the cutaneous surface

This article describes how computer models of the skin can be used to obtain objective information about surface-altering events. Although alterations produced by various forms of therapy are being emphasized, more needs to be known about alterations produced by aging, environmental factors, and disease. The term "automated optical surfometry" has been applied to the method described in this chapter. (The term "optical profilometry" has also been used. Because this designation was applied at an earlier time to a method that is entirely different, the use of the word "optical surfometry" appears to be preferable as well as more accurate). Space limitations made it possible to allude only briefly to some of the other techniques that are being used to learn more about the configuration and dynamics of the surface of the skin. The development of imaging and modeling methods for topographic studies of the skin owe their origins in large measure to the advent of inexpensive computer technology.
