The procedure is based on the 3D scanning of the arm using the Occipital Structure Sensor and an ad-hoc developed application, named Lym 3DLab.  Lym 3DLab emulates the traditional measurement methods, which consist in taking manual circumference measurements or using the water displacement method.  A validation test has been performed to compare the measurements computed by Lym 3DLab with both water displacement and manual circumference measurements.  The comparison between the perimeters of cross sections computed with Lym 3DLab and the circumference measurements has shown results that are very accurate with an average difference of 2 mm.
