Abstract:
This paper presents experimental multispectral 3D surface scanning system RoScan, which is capable of capturing
3D models of a surface, containing a spatial representation of the object, colour of each point of the
surface, its temperature and roughness. Such models are provided with accuracy up to 0:12 mm and thermal
resolution of 0:05C, what makes it suitable for 3D thermal body scanning in medicine. Basic principles,
parameters, and functional capabilities are discussed, and developed tools for data analysis are presented. The
RoScan system is suitable for early detection of inflamed regions and its objective quantification. It can be
also used for evaluation of treatment suitability or for monitoring during a recovery process. To show this,
the case study monitoring of inflammation related to eczema caused by an allergic reaction is presented. The
inflammation development is studied using RoScan during eczema growth and after the application of two different
external dermatolog
ics – Protopic R
0.1% topical ointment and ointment from shea butter and coconut
oil. On this particular subject, measured characteristics demonstrated a stronger effect of Protopic R
0.1% on
eczema healing, as the evolution of inflammation in the area treated with this dermatologics started to recover
earlier and culminated on the lower value of temperature gradient then the second ointment.
