SORRY, THIS PAGE IS STILL IN PREPARATION...
"Mole Mapping" is a term used for the technical procedure to reliably
record and assess the multiplicity of melanocytic moles or pigmented
spots on the skin surface through a videographic cartography = lesion
pattern mapping.
The topodermatographic image analysis is done with the use of a
CCD-(chip) video camera capturing a skin surface image of the skin
section selected, which is then digitized over a frame grabber into an
image file for computer-aided image processing technology. This image
processing technology, termed "computer-aided topodermatographic image
analysis (CATIA)" or "topodermatography" is a patent-protected procedure
using a specifically adjustable positioning framework device and a
specifically designed image processing software (Microsurf Areascan®).

see a static DEMO sequence... If multiple moles/pigmented lesions are
peppered over the skin surface, nobody really will be able to only count
them. Following doubtful lesions over time in order to exclude
premalignant changes indicated by lesion growth (preceding additional
changes in contour configuration and color), is hardly - if ever -
achievable by simply looking at them from time to time: You might miss
early signs of change, which could alert you timely.
Topodermatography is of great value in objectively assessing the number,
sizes, distribution, and time-based changes of melanocytic moles on the
skin surface. To give you a visual impression of how the technology
works, you are invited to click through the image sequence provided
here. The objective of this demo presentation was to demonstrate that
the topodermatographic technology is capable to find, count, and assess
lesional sizes and lesion changes with a critical resolution of 0.5 -
1.0 mm, which is quite more accurate than required for any clinical
purposes. For this purpose, the case presentation was based upon a
"worst case scenario": The individual presented had small-sized
lentiginous spots on the skin only, with a diameter of .5 - 1.5 mm. So,
if the system is capable to accurately detect and measure these lesions,
it would do so even in larger pigmented spots.
In addition, we switched off the illumination lights at the right body
surface flank, just to demonstrate how accurately the software is
capable of assessing the lesion pattern even if the illumination
conditions are worse.
