3D Anatomical Human

3D Anatomical Human

INRIA project @Geneva, Switzerland (2010). The 3D Anatomical Human (3DAH) project is a EU Marie Curie Research and Training Network (RTN). The objective is to increase the development of technologies and knowledge around virtual representations of the human body for interactive medical applications. More specifically, the network aims at developing realistic functional 3D models of the musculoskeletal system, the methodology being demonstrated on the lower limb.

The main areas of research are:

  • motor control analysis: simulation of the lower limb;
  • computer graphics: efficient simulation of humans;
  • biomechanics: accurate tissue characterization and mechanical simulation;
  • image processing: modelling of organs from images;
  • orthopaedics: resolution of particular pathological problems.

Partners of this project include:

  • AAU - Aalborg Universitet (DK);
  • CRS4 - Centro di Ricerca, Sviluppo e Studi Superiori in Sardegna (IT);
  • EPFL - École Polytechnique Fédérale de Lausanne (CH);
  • INRIA Sophia-Antipolis - Institut National de Recherche en Informatique et en Automatique (FR);
  • UNIGE - Université de Genève (CH);
  • UCL - University College London (UK);
  • VUB - Vrije Universiteit Brussel (BE).

In this project, my work consists in segmenting anatomical structures of the lower limb (e.g. muscles, bones and ligaments) from static and dynamic Magnetic Resonance (MR) images. Because of the variability of these structures, the segmentation is performed by combining non-rigid image registration with segmentation based on deformable models.

3D reconstruction

3D reconstruction

INRIA project @Geneva, Switzerland (2009). We are interested in the 3D reconstruction of the lower limb anatomical structures. The proposed method starts with a Magnetic Resonance (MR) image acquisition during which the lower limb of a subject is scanned. 3D models are generated after a manual segmentation of the anatomical structures. However, the surface of the models appears not to be smooth and the models are not attached whereas they should be anatomically.

Various consecutive steps are needed to constrain the models to be correct at the anatomical level. The aim of our method is to reuse these models with automatic segmentation methods.

This work is a collaboration between:

  • INRIA Sophia-Antipolis - Institut National de Recherche en Informatique et en Automatique (FR);
  • UNIGE - Université de Genève (CH).

Our modeling approach allowed us to generate most of the anatomical structures of the lower limb, such as bones, muscles and tendons. We were able to create a total of 109 models including the bones, muscles, tendons and skin. Regarding the bones, we modeled 6 in total. More specifically, the hip, femur, patella, tibia, fibula and foot bone. Finally, we modeled 34 muscles in total. For each muscle, we modeled a pair of tendons (proximal and distal) whose role is to attach muscles to bones. The generated models were evaluated and validated by a medical expert.
