Heat transfer analysis and resolution quantification of active dynamic thermography through human skin.

Objectives: Active dynamic thermography (ADT) is a non-contact imaging technique that characterizes non-homogeneities in thermal conductance through objects as a response to applied energy stimulus. The aim of this study was to (i) develop a heat transfer model to define the relationship between thermal stimulation and resolution and (ii) empirically quantify the resolution an ADT imaging system can detect through a range of depths of human skin.

Materials And Methods: A heat transfer model was developed to describe a thermally non-conductive object below a sheet of skin.
