Goal: To graphically edit anatomical models to match constraints

ContactFrançois Faure


Using our recent work on Anatomy Transfer it is possible to automatically generate personalized 3D anatomical models based on medical images (MRI or CT) as illustrated below, by registrating a generic model to a personalized morphology.


Anatomy Transfer using an MRI image.

However, while precision is surprisingly high when enough information is extracted from the image,  the reconstructed surfaces do not perfectly match the image when few constraints are available, such as in the example below.


Model mismatch. In this example, only the skin was used to constrain the registration, and one can see in this slice that the transferred organs (in red and green) do not perfectly match the MRI image everywhere.

Proposed work

The objective of this project is to propose a novel graphical editor to quickly correct the mismatches.

In the first part, classical segmentation tools will be applied to locally correct the surfaces. Once the capabilities and limitations of this approach are clear, we will investigate higher level methods.

In the second part of this work, we will provide the user with novel tools to apply constraints in the registration process, by  setting up registration constraints in the 2D slices or directly in 3D. These constraints will be converted to forces applied in the mechanical relaxation of a physical model.


The results may be used to improve the technology of  the Anatoscope startup company. This work may be continued as a PhD thesis, or  engineering work in the company.
