User friendly computer profilometry.
Portable optical profilometer for measurement and analysis of the human back shape has been developed. The driving user friendly software includes correction of distortion of the observation lens, data calibration, three-dimensional Z-axis rotation of the patient normalizing his position, calculus of the curvature map (second derivative), and precise indication of different characteristic points of the back including the spinous processes line. This instrument enables the examination of the back in both erected and bent positions.
