Abstract
Cryogen spray cooling (CSC) is a heat extraction process that protects the
epidermis from thermal damage during dermatologic laser surgery. The
objective of the present work is to investigate radial and temporal variations in
the heat transferred through the surface of a skin phantom during CSC. A fast-
