Full textThis thesis “Acquisition of stereoscopic images and camera calibration with genetic algorithms: application in the biomedical domain” consists to define a complete tool for acquiring the topography and texture of a 3D surface in order to apply it in the dermatological and more generally in the biomedical field.First, the objective is to study and to specify or design hardware devices such as professional cameras, assembly systems for stereo equipments, lighting system and trigger system for devices.Then, the thesis focuses on algorithmic and software aspects which relate to all mathematic and computational treatments needed to obtain a 3D surface.One of major issues addressed is the geometric calibration of stereo cameras. The developed approach pushes the limits of conventional methods in this field by proposing the use of more efficient and easier to implement optimization methods.We have shown that the algorithms using the principles of genetic algorithms can obtain more reliable results than their competitors and they can deal more easily the variable conditions of experiments.The real applications of our genetic algorithm for camera calibration cover many acquisition devices (industrial cameras, SLR cameras, stereo microscopes, beam splitters, pinhole and telecentric objectives), each acquisition device is adapted to a specific use following the requested study (microscopic areas, face or body parts). This thesis “acquisition / calibration” is a part of a global system called VirtualSkinLAB

Full textResearch of new selectivity means for laser treatment in the biomedical domain is not currently an active field, contrary to the analysis of cells and tissues by light which is in an intense phase of evolution. My work consisted of proposing a selective light deposition system and of looking for the potential applications of such a device. I have achieved an experimental setup using a liquid crystal spatial light modulator and allowing the control of the light repartition relating to the video image of the surface to be treated. This control uses an automatic image analysis. Experimental results have allowed the evaluation of the performances that can be actually reached by the irradiation system. In fact we get a spatial resolution about 30 æm without having reached the limits of our system, and a hardiness and a simplicity of implementation because we use no mobile parts in the system. On the other hand our solution is limited as for the maximal dose of the deliverable energy. Function of the actual performances and those that we think accessible after adding improvement, we have tried to look for the application for which this irradiation system could have a consequent contribution. We have been brought to put a side the most current applications of laser treatments because of either the implemented biologic processes or the limitations of the system. However it appears that the characteristics of the system seem to be perfectly adapted to the manipulation of the cellular and tissular growth

Full textFrom decades now, nanomaterials and especially superparamagnetic iron oxide nanoparticles are studied for their numerous applications in nanomedecine area. The biocompatibility and the magnetic properties of such nano-objects allow their utilization for diagnostic (MRI, optical imagery, PET…) and for therapy application (nanovectorization, hyperthermia…) During this thesis work, the first step was to study the influence of several synthesis parameters on the final properties of the magnetic iron oxide nanoparticles. The aim of this study was the development and the optimization of the widely used way of synthesis by co-precipitation modified by a ligand addition during the growth step of the synthesis. Citrate capped iron oxide nanoparticles with a controlled size between 4 and 13 nm have been synthesized, the saturation magnetization of these nanoparticles reach 75 emu/g of iron oxide, this value is particularly high for nanoparticles of such sizes. During this work, the large panel of characterizations performed on these nanoparticles (TEM, XRD, Mössbauer, FTIR, XPS, DLS, Magnetic measurement) allowed to study precisely the relations between size, ligand ratio, composition and magnetic properties of the synthesized nanoparticles. The interaction between the synthesized citrate capped nanoparticles and biological materials such as human cells have been investigated in-vitro notably to evaluate cells internalization and citotoxicity. In a second step, some additional works have been performed on the citrate capped iron oxide nanoparticles in order to replace the citrate ligand by a bio-inspired polymer (poly-oxazoline). This polymer can have multiple biomedical applications depending of the pendent chemical groups that have been fixed on it

Full textThe penetration capacity of the electromagnetic (EM) waves in matter or biological tissues allows exploring media non-destructively. Concerning the public health sector, improving the quality of life has become one of the greatest concerns of nowadays society. EM wave research on different media and biological tissues shows a great potential for diagnostic applications and eventually for therapeutically applications. In this doctoral thesis, we focus on the vast domain of the biomedical applications of wave-matter interactions, based on the knowledge of the electromagnetic properties of matter, the complex permittivity and the conductivity. On a first instance, we address the emerging domain of ultra-high field MRI (Magnetic Resonance Imaging), which nowadays puts effort into the clinical implementation of 7T devices. Firstly our purpose is to produce an anthropomorphic head model, composed of the brain’s different layers, and taking into account the electromagnetic properties and the proton relaxation times inherent to each tissue. These realistic head models allow to evaluate the newly developed protocols for these ultra-high field devices. Secondly, we have studied and developed field homogenization devices, which allow brightening the shadow areas displayed in some MRI images, such as the cerebellum and the temporal lobes in brain imaging at 7T. This procedure, named Passive Shimming, is based on the use of high permittivity dielectric pads composed of Barium Titanate, which focalize the field to the areas where normally the wavelength in insufficient to generate a homogeneous signal distribution
