[A special software for area and volume measurement and 3D image of skin expander].

OBJECTIVE
A special software for measuring expanded skin area and volume and creating a 3D image of skin expander protrusion has been introduced.


METHODS
The 3D coordinates of all the points on the surface were obtained by means of interpolation in computer, according to its base, central horizontal and vertical sections that should be adopted in advance. This software was programmed with C language and performed in Microsoft Windows.


RESULTS
The area, volume, and 3D image were acquired according to 3D coordinates. The deviation of the software measurement was less than 4% of actual sizes at most in our reliability demonstration.


CONCLUSION
This software, combined with our protocol of conversion from tridimensional surface to a plane reported previously, makes up a preferable scheme in this field.
