Post-doctoral position in Medical Imaging
Ecole Centrale de Paris/INRIA Saclay, Ile-de-France
Topic: Multi-Modal Registration of Medical Images
Research Context:
Registration between pre-operative and Interventional data is a major challenge and demand in a number of surgical operations In such a context, first the operation procedure and the target are determined through the use of high resolution appropriate imaging modalities. This information is then used as guide for surgeons in the operation room. To this end an alignment between the pre-operative data and the acquisition on the fly during the surgery is required. The use of global parametric transformations assumes that the tissue remains static that is not the case when one has to account for tissue shift because of the cut and an alignment that also involves a local deformation component is to be considered.
Post-doctoral Research work Description:
The aim of this post-doc is to address registration between pre-operative 3D annotated data and 2D interventional images during surgery. In such a context, the use of discrete optimization will be considered, where one seeks for an out of plane projection of the 2D images to the 3D volume and an in-plane non-rigid deformation towards addressing tissue shift. Efficient techniques from discrete optimization will be considered to address the problem. The estimation will decomposed into a master (plane selection) and a slave problem (in plane deformation). In order to account for different modalities, a kernel-based approach will be considered. Once such a metric has been determined, the registration will be casted using a continuous interpolation model over non-uniform control points. This is a joint work with one of the leading university hospitals in Paris. Successful candidates are expected to contributer with other ongoing project in the field of medical image analysis and computer aided diagnosis.
Required knowledge and background:
PhD in electrical or computer engineering, or computer science or applied mathematics in the areas of medical imaging or computer vision demonstrating ability to carry on research of excellent quality. Prior work on registration, motion analysis or discrete optimization will be a plus while good programming skills in Matlab and C++ and ability to work in a team will be appreciated.
