Full textLes méthodes d'affichage interactives permettent à l'utilisateur d'explorer des environnements virtuels en réalisant l'affichage des images à une cadence suffisamment élevée pour donner une impression de continuité et d'immersion. Malgré les progrès réalisés par le matériel, de nouveaux besoins supplantent toujours les capacités de traitement, et des techniques d'accélération sont nécessaires pour parvenir à maintenir une cadence d'affichage suffisante. Ce travail s'inscrit précisemment dans ce cadre. Il est consacré à la problématique de l'élimination efficace des objets masqués, en vue d'accélérer l'affichage de scènes complexes. Nous nous sommes plus particulièrement intéressé aux méthodes de précalcul, qui effectuent les calculs coûteux de visibilité durant une phase de prétraitement et les réutilisent lors de la phase de navigation interactive. Les méthodes permettant un précalcul complet et exact sont encore hors de portée à l'heure actuelle, c'est pourquoi des techniques approchées leur sont préférée en pratique. Nous proposons trois méthodes de ce type.
La première, présentée dans le chapitre 4, est un algorithme permettant de déterminer de manière exacte si deux polygones convexes sont mutuellement visibles, lorsque des écrans sont placés entre eux. Nos contributions principales ont été de simplifier cette requête, tant du point de vue théorique que du point de vue de l'implémentation, ainsi que d'accélérer son temps moyen d'exécution à l'aide d'un ensemble de techniques d'optimisation. Il en résulte un algorithme considérablement plus simple à mettre en oeuvre que les algorithmes exacts existant dans la littérature. Nous montrons qu'il est également beaucoup plus efficace que ces derniers en termes de temps de calcul.
La seconde méthode, présentée dans le chapitre 5, est une approche originale pour encoder l'information de visibilité, qui consiste à stocker l'ombre que générerait chaque objet de la scène s'il était remplacé par une source lumineuse. Nous présentons une analyse des avantages et des inconvénients de cette nouvelle représentation.
Finalement, nous proposons dans le chapitre 6 une méthode de calcul de visibilité adaptée aux scènes d'intérieur. Dans ce type d'environnements, les graphes cellules-portails sont très répandus pour l'élimination des objets masqués, en raison de leur faible coût mémoire et de leur grande efficacité. Nous reformulons le problème de la génération de ces graphes en termes de segmentation d'images, et adaptons un algorithme classique, appelé «watershed», pour les obtenir de manière automatique. Nous montrons que la décomposition calculée de la sorte est proche de la décomposition classique, et qu'elle peut être utilisée pour l'élimination des objets masqués.

Full textBACKGROUND AND AIM: Portal vein occlusion by ligation (PVL) or embolization (PVE) is routinely performed to increase inadequate future liver remnant volume (FLRV) . The higher liver regeneration rate observed after PVE than after PVL may be due to the formation in the latter of intrahepatic porto-portal collaterals between the portal branches of segment 4 and the branches of the adjacent right segments 5 and 8. The aim of the study was to compare liver regeneration rate following portal vein ligation (PVL) with (Alc+) and without (Alc-) simultaneous intraportal alcohol injection METHODS: Forty-two patients with colorectal liver metastases who underwent PVL between January 2004 and June 2014 were analyzed. Beginning in September 2011, absolute alcohol was injected prior to right PVL. Future liver remnant volume (FLRV) was assessed by CT-scan. CT-scans were reviewed to assess recanalization and/or cavernous transformation of the occluded portal vein. Liver regeneration was assessed as Volumetric Increase (VI) [(FLRVpost% – FLRVpre%)/FLRVpre%]. RESULTS: The Alc+ (n=23) and Alc- (n=19) groups were similar in age, sex, diabetes, pre-PVL FLRV and administration of chemotherapy. The rate of recanalization of the occluded portal vein was significantly higher (63.1% vs. 4.3%, p<0.001) and the rate of cavernous transformation higher (36.8% vs. 8.7%, p=0.055) in the Alc- than in the Alc+ group. Post-PVL FLRV (43.3±14.3% vs. 34.6±6.4%, p=0.013) and VI (0.44±0.24 vs. 0.28±0.20, p=0.029) were significantly higher in the Alc+ group. Univariate analysis showed that male sex (0.23±024 vs.0.40±0.19, p=0.005) and PVL without alcohol injection (0.35±0.24 vs. 0.26±0.20, p=0.035) were negatively correlated with VI. Multiple regression analysis showed that male sex (B=−0.149, p=0.035) and alcohol injection (B=0.143 p=0.041) significantly predicted VI [F(1,40)=5.200, p=0.010]. CONCLUSIONS: Alcohol injection prior to PVL significantly increased regeneration rate of the future liver remnant, reducing recanalization of the occluded portal vein.

Peripheral artery occlusive disease (PAOD) has been a common symptom in many diseases and its risk increases sharply with age. Therefore detecting lower limb PAOD is important for patients to prevent disabling claudication, ischaemic rest pain and gangrene. The purpose of this research is to develop a portable and non-invasive microcirculation measurement system using the photo-electronic technique based on photoplethesmography (PPG) and arterial oxyhemoglobin saturation (SaO2) to evaluate the microcirculation state of PAOD patients. This device provides a help for diagnosis of peripheral artery abnormalities and a tool for health home-care. This device was mainly divided into two steps. First, the three channels PPG and one channel ECG was set up for measuring physiological parameters such as PTTf, PTTp, RT, and SaO2. Secondary, we evaluated the microcirculation by those parameters in different measuring point. The statistical results show that the significant differences between the bilateral sites (ΔPTTp andΔPTTf) are useful parameters for evaluating microcirculation in PAOD patients. Those results also indicated that the laser-based microcirculation measurement system in this study could be a tool for diagnosis or healthy home-care to determine the artery circulation state of PAOD patients.
