“…In our opinion, the above algorithm, taking into account all its inherent limitations, can nevertheless be used as a decision support tool for the prosthetic expert and 3D designer considerably reducing the workload of qualified personnel. Among relevant analogues, the work [28] should be mentioned, where 2D cross-sections of the upper and lower limbs 3D-model were used to create a "bone structure". The sections were created by placement of any number of parallel planes inside the 3D-model and calculating corresponding intersections between the 3D-model and the plane.…”

Modern prosthetics largely relies upon visual data processing and implementation technologies such as 3D scanning, mathematical modeling, computer-aided design (CAD) tools, and 3D-printing during all stages from design to fabrication. Despite the intensive advancement of these technologies, once the prosthetic socket model is obtained by 3D scanning, its appropriate orientation and positioning remain largely the responsibility of an expert requiring substantial manual effort. In this paper, an automated orientation algorithm based on the adjustment of the 3D-model virtual anatomical axis of the tibia along with the vertical axis of the rectangular coordinates in three-dimensional space is proposed. The suggested algorithm is implemented, tested for performance and experimentally validated by explicit comparisons against an expert assessment.
