Bodymetry & Life Science
The methods of continuously optimised industrial 3D metrology and digitisation increasingly diversifies into non-industrial application fields, such as dental medicine, cosmetics or even animated effects in the film industry. With special solutions for precise non-contact digitising of teeth, skin, faces or complete bodies, Breuckmann is your competent, experienced partner.
PrintMeasurement of the Skin Surface
The dermaTOP-blue System with its contactless working digitisation allows fast, reproducable and precise capturing of the 3D information of wound surfaces and cicatrices.
Our in-vivo scanner dermaTOP-blue was specially optimised for dermatological and cosmetic applications, for precise measurement and examination of human skin without the need of replicas.
The sensor is equipped with a narrow-band light source in the blue spectral range ensuring to depict the skin structure with optimum contrast. The result is an even more reliable analysis of roughness and other characteristic features of the dermal topography.

Introduction
The exact and prompt evaluation of wound dimensions in the context of chronic wounds, to date still presents a difficulty in connection with the increasing requirement of wound documentation. Even in wound care centres, accurate three dimensional measuring techniques are not yet applied as routine standards, as they are safely available. Using the “miniaturised projection technique” (dermaTOP) makes it possible to achieve the generation of a precise, contact free and non-invasive topometrical surface structure of chronic wounds.
Material and Methodology
Ten patients suffering from chronic venous, arterial, combined arterial – venous and diabetic ulcers have been included in this particular measurement research study. dermaTOP involves an optical measuring procedure, using a combination of Gray-Code and Phase-Shift techniques for the generation of 3D information. The projection units as well as the CCD camera are fixed in a so called triangulation angle. By means of projected grids in different phasing locations, a precise, reproducible 3D reconstruction of the surface is generated. The digitisation time takes less than 800 ms; the measuring area was positioned in a 10 x 10 cm area.
Results
In a fraction of time, the wound surfaces of all patients have been successfully measured three-dimensionally (including the total volume). The high depth of field allowed for repeated measurements of the mathematical 3D surface structure information as well as the optical topometrical structure without the loss of lateral and horizontal resolution in the context of curved surfaces.
Conclusion
dermaTOP provides a new approach for the measurement of skin surface structures in the context of chronic wounds. The contact free acquisition technique allows for a fast (< 1s) generation of three-dimensional, reproducible and precise information data of the wound area.
