Abstract : Objective: We assessed whether or not pain relief could be achieved with a new system that combines 3D augmented reality system (3DARS) and the principles of mirror visual feedback. Methods: Twenty-two patients between 18 and 75 years of age who suffered of chronic neuropathic pain. Each patient performed five 3DARS sessions treatment of 20 mins spread over a period of one week. The following pain parameters were assessed: (1) visual analogic scale after each treatment session (2) McGill pain scale and DN4 questionnaire were completed before the first session and 24 h after the last session. Results: The mean improvement of VAS per session was 29\% (p < 0.001). There was an immediate session effect demonstrating a systematic improvement in pain between the beginning and the end of each session. We noted that this pain reduction was partially preserved until the next session. If we compare the pain level at baseline and 24 h after the last session, there was a significant decrease (p < 0.001) of pain of 37\%. There was a significant decrease (p < 0.001) on the McGill Pain Questionnaire and DN4 questionnaire (p < 0.01). Conclusion: Our results indicate that 3DARS induced a significant pain decrease for patients who presented chronic neuropathic pain in a unilateral upper extremity. While further research is necessary before definitive conclusions can be drawn, clinicians could implement the approach as a preparatory adjunct for providing temporary pain relief aimed at enhancing chronic pain patients’ tolerance of manual therapy and exercise intervention. Level of Evidence: 4.

Abstract : This article presents an original method for long objects modeling and two navigation applications in trauma surgery. Both concern long bone fracture treatment. Our modeling method requires only two x-ray views. The projection cones of the object are determined and their intersection is computed, providing an approached 30 model, which can be improved by adding a priori knowledge or other information. The first application concerns the control of diaphyseal fracture reduction treated by external fixation. Reference frames are fixed to the bone fragments and tracked by a 3D optical localizer, allowing the computation of their relative position. Approached 3D models of the fragments are displayed in real time according to the manipulation effected by the surgeon. The principal axes of the fragments, very useful for the fracture reduction, are also displayed. The alignment of the bone fragments is quantified by parameters provided in real time during the reduction. The second application concerns the distal locking of intra-medullary nails. A 3D model of the nail and its locking holes is built from two calibrated fluoroscopic views. The nail and the surgical tool are tracked thanks to reference frames fixed to each of them. A 3D view of these two elements is displayed in real time, guiding the surgeon in the difficult task of distal targeting. Experiments and results are presented for both applications. These techniques provide real 3D models to the surgeon during the operation, allowing precise guidance of the surgical gesture and considerable reduction of the irradiation to the patient and the surgical team.

Abstract : In oncology, combating the spread of tumor cells is a clinical need which currently remains unsatisfied. Identifying anti-migratory compounds usually requires in vitro screening of a large number of molecules. Efficient and realistic (i.e., preferably 3D) in vitro tests are thus required in order to quantify the anti-migratory effects of anti-cancer drugs. To remain compatible with high-throughput screening, we focus on assays where unlabeled cells are migrating in 3D transparent gels and are observed under time-lapse 3D phase-contrast microscopy. In this context, we present a method for automatically tracking cells that combines a template matching preprocessing step with a mean-shift process. The preprocessing step consists in performing a correlation of a cell template with each observed volume in order to provide a phase-contrast artifact-free volume where the cells appear as correlation peaks surrounded by smooth gradients. This transformation enables the cells to be efficiently tracked by a mean-shift process. Robustness and efficiency of this approach are qualitatively and quantitatively shown in various experiments. Finally, we successfully applied our method to the quantitative characterization of the anti-migratory impact of cytochalasin-D on cancer cells. In conclusion, our method can efficiently be used for drug screening aiming to evidence drug-induced effects on cell migration in 3D transparent environments, such as matrix gels.

Abstract : Topographical data producers are currently confronted with the need for a faster updating method. Indeed, this need was assessed at the first stage of the ARMURS(∗) project by surveying several Belgian and international mapping agencies. The aim of the project is to build a demonstrator to assist data producers in planning the update of their topographic database more efficiently relying on remote sensing images, together with socio-economic and demographic data. At a regional scale, the man-made structure changes extracted by the ETATS module on a SPOT5 panchromatic image will be fused with a change analysis on socio-demographic data. At a local scale, as regards areas of predicted changes, the older databases are compared with recent very high-resolution satellite or aerial images in order to detect changes in man-made structures. Changes are detected by comparing an object-oriented classified VHR image to a simplified version of the old database. This object-oriented approach consists in a segmentation followed by a classification. Three segmentation methods (Watershed Assembly, Graph Cut, Mean Shift) were implemented and compared to the one of a commercial software (Definiens); indices were proposed to assess the quality of these segmentations. Features are selected either according to a visual interpretation formalised into an interpretation key, or by quantitative methods such as the forward Jeffries-Matusita distance or mutual information criteria (mRMR); selections are compared. By using a common framework (images, training set and validation set), existing classification methods available in Definiens and in R are compared. A final step of change detection gives us preliminary results.

Abstract : OBJECTIVES: The purpose of this study is to determine the factors influencing the spatial precision and the replicability of electromagnetic trackers (EMT) for the localization of electrodes and natural landmarks on the patient's head. MATERIALS AND METHODS: The effects of seven conditions on the measurement of the EMT were investigated with a Polhemus Fastrack: distance, contact between two components of the EMT, presence of magnetic object, localization of landmarks and electrodes on a phantom and a human subject without and with movements. RESULTS: The EMT has a precision of 0.15mm+/-0.36mm for the measurements made on still objects in a non-magnetic environment. On a human subject, the mean variation of the nasion position is 1.6mm+/-1.46mm and 2.7mm+/-1.40mm for the tragus. The increase of the electrode measurement dispersions is significant between the phantom and the human subject with a mean variation of 2.39mm+/-1.26mm. In certain conditions, up to 15\% of the measurements may be considered as outliers. CONCLUSION: The precision significantly decreases for this application in the following cases: (1) physical contacts between the stylus/transmitter/receiver cables, (2) presence of magnetic objects in the surrounding of the EMT system, (3) skin and hair softness and (4) subject's head movements.

Abstract : Background. The RFA procedures rely on a precise positioning of the radiofrequency electrode and the complete destruction of the tumour. This article presents new optimization techniques to improve such surgical procedures.Methods. A method to optimize the coverage of the tumour by successive RFA destructions and an in vitro procedure with simulated tumours have been developed.Results. The guidance system and optimization coverage have been tested on 3D simulation and by the surgeon in vitro on a heifer liver. In this context, the RFA electrode is optically tracked and guided.Conclusions. The optimization method provides needle placements that ensure a complete theoretical ablation of the tumour, and the guidance system helps the surgeon to reach each position of destruction.

Abstract : Background. The reduction of long bone fractures treated with external fixation is usually performed with fluoroscopic images, which include several disadvantages: 2D information, distortions, and irradiation to the patient and the surgical team. This article presents a new navigation technique to control the reduction of such fractures while minimizing the irradiation.Methods. Optically tracked markers are fixed to pins inserted into the bone fragments. These last are modelled using two initial calibrated radiographs. The models can be improved with several types of anatomical data and are displayed in real time.Results. This navigation system was tested on dry bones and an anatomical specimen leg.Conclusions. This new technique allows the visualization of the fracture in real time and from any viewpoint during the reduction. Irradiation is minimized using only two X-ray images.

Abstract : Radio frequency ablation (RFA) is a minimally invasive treatment for either hepatocellular carcinoma or metastasis liver carcinoma. In order to resect large lesions, the surgeon has to perform multiple time-consuming destruction cycles and reposition the RFA needle for each of them. The critical step in handling a successful ablation and preventing local recurrence is the correct positioning of the needle. For small tumors, the surgeon places the middle of the active needle tip in the center of the tumor under intra-operative ultrasound guidance. When one application is not enough to cover the entire tumor, the surgeon needs to repeat the treatment after repositioning of the needle, but US guidance is obstructed by the opacity stemming from the first RFA application. In this case the surgeon can only rely on anatomical knowledge and the repositioning of the RFA needle becomes a subjective task limiting the treatment accuracy. We have developed a computer assisted surgery guidance application for this repositioning procedure. Our software application handles the complete process from preoperative image analysis to tool tracking in the operating room. Our framework is mostly used for this RFA procedure, but is also suitable for any other medical or surgery application. © 2008 Elsevier Ltd. All rights reserved.

Abstract : In vitro cell imaging is a useful exploratory tool for cell behavior monitoring with a wide range of applications in cell biology and pharmacology. Combined with appropriate image analysis techniques, this approach has been shown to provide useful information on the detection and dynamic analysis of cell events. In this context, numerous efforts have been focused on cell migration analysis. In contrast, the cell division process has been the subject of fewer investigations. The present work focuses on this latter aspect and shows that, in complement to cell migration data, interesting information related to cell division can be extracted from phase-contrast time-lapse image series, in particular cell division duration, which is not provided by standard cell assays using endpoint analyses. We illustrate our approach by analyzing the effects induced by two sigma-1 receptor ligands (haloperidol and 4-IBP) on the behavior of two glioma cell lines using two in vitro cell models, i.e., the low-density individual cell model and the high-density scratch wound model. This illustration also shows that the data provided by our approach are suggestive as to the mechanism of action of compounds, and are thus capable of informing the appropriate selection of further time-consuming and more expensive biological evaluations required to elucidate a mechanism.

Abstract : One of the biggest problems usually encountered by the clothes manufacturer consists of placing various pattern parts on a rectangular area in such a way that the waste of material between the pieces is minimized. To bring some automated help in this field, computer programs need first to handle the complicated contours of the pieces. One needs not only to check the overlap of two contiguous patterns, but also to compute their precise area of intersection, allowing in this way the use of some kind of combinatorial optimization. In a wider context, it is possible to design a general purpose algorithm, able to build the complete structure representing the intersection of two polygons. It is remarkable that the same algorithm can also be used, with only a few modifications, to compute the union and the difference of any two polygons. Copyright © 1991, Wiley Blackwell.

Abstract : Dans le cadre du projet de développement de salles d’opération numériques intégrées « integrated Digital Operating Theater » (iDOT), une application, permettant de visualiser de manière synchronisée plusieurs flux de données collectés pendant une opération chirurgicale, a été développée. Elle offre la possibilité de reconstruire la phase d’observation d’une chirurgie dans son ensemble et d’interagir aisément avec les données. Une telle application permet de dépasser les limites spatiales et temporelles liées à la présence en salle durant une opération, en offrant la possibilité de rejouer ses différentes étapes quand et o{\`u} l’on veut. Cela constitue donc un excellent outil pédagogique pour l’enseignement de la chirurgie en permettant aux étudiants d’accéder à l’ensemble des données peropératoires utilisées par le praticien et d’observer une opération sans devoir se trouver en salle pendant son déroulement.
