Evaluation of new diagnostic procedures of medical thermography – in-vivo experiments

Abstract

The advantages and disadvantages of active thermography in medical diagnostics using different thermal excitations: halogen lamps as a heating source and ice and a fan as cooling sources are discussed. A new procedure of tissues thermal properties identification and a new image processing method used to increase contrast between healthy and injured tissues are described. In-vivo experiments prove validity of proposed methods.

Thermal imaging and modelling of burned skin

“…We performed ADT experiments using the procedure and configuration of instrumentation described in our former publications [1,2,3,4,5,6,7], based on IR imaging of thermal transient processes after external pulse excitation. Using equipment: a high quality IR camera Flir SC 3000, quantum well FPA LW of 25 mK resolution and 60 Hz acquisition rate for capturing of series of thermal images during and after cooling and a cryotherapy device using CO2 vapour, with specially designed applicator to get uniform cooling of tested skin of animals were applied - Fig.1.…”

The influence of carbon dioxide on dynamic thermography results

“…We can distinguish from heating or cooling of the examined object Heating can be achieved by halogen lamps [1], microwave [2], ultrasound [3], etc.. Cooling can be performed by applying stream of cold air [4], cold water, ice, vaporous fluids [5] or as in our application the stream of CO2 [6]. In biomedical applications cooling has its special role.…”
