Important improvements and breakthroughs in microscopy acquisition methods can be achieved by incorporating innovative signal/image processing ingredients directly into the acquisition and/or reconstruction protocols, and by developing the new paradigm of mathematical microscopy. We will present recent work on Structured Illumination Microscopy (SIM) that is based on a Bayesian inverse problem formulation approach that enables the computation of one high-resolution image from a reduced number of low-resolution images and has no specific constraints on the modulation pattern. We will demonstrate the efficiency of this approach through numerical evaluations on simulated data and examples on real microscopy data. Then we will show how compressive sensing can be used as a denoising tool in bioimaging. Multiple reconstructions at low sampling rates are combined to generate high quality denoised images using total- variation sparsity constraints. The validity of the proposed method will be first illustrated on synthetic images with known ground truth and then applied to real biological images.


Jean-Christophe Olivo Marin is the head of the Bioimage Analysis Unit, the CTO and director of the Center for Innovation and Technological Research at Institut Pasteur, Paris. He has chaired the Cell Biology and Infection Department at Institut Pasteur, Paris and was a cofounder of the Institut Pasteur Korea, Seoul, South Korea. His research over the years has been centred about developing new algorithms for multi-particle tracking, active contours models, image segmentation, microscope modelling and mathematical imaging. He is an IEEE Fellow, a SPIE Fellow, an IEEE Signal Processing Society Distinguished Lecturer, and chair of the IEEE International Symposium on Biomedical Imaging Steering Committee.


Musculoskeletal wide detector CT: principles, techniques and applications in clinical practice and research – Vendredi 20 mai 2016 – 9H

 Blum A, Teixeira P.


A progressive increase in the detector width in CT scanners has meant that advanced techniques such as kinematic, dynamic, perfusion and dual-energy CT are now at the radiologist's disposal. Although these techniques may be important for the diagnosis of various musculoskeletal diseases, data acquisition and interpretation can be challenging. This presentation offers a practical guide for the use of these tools including acquisition protocol, post-processing options and data interpretation based on 7 years of clinical experience in a tertiary university hospital.
