About Marseille System

In 1975, the results of studies at the prestigious Pasteur University in Marseille, France, established an objective analytic system.  This system has been refined by enhanced knowledge of basic science and increased clinical experience but remains the basis for breast thermology (the diagnostic science of infrared imaging) to this day.

Termed the Marseille system, this analytic method provides for a TH-1 – TH-5 scale as a summary based upon specific, objective and quantitative thermal features and differential levels of infrared energy.  Thermal features are divided into Signs and Criteria based upon their established characterization of breast disease.
