The noninvasive evaluation of the cardiac function presents a great interest for the diagnosis of cardiovascular diseases. Cardiac tagged MRI allows the measurement of anatomical and functional myocardial parameters. This protocol generates a dark grid which is deformed with the myocardium. Tracking the grid allows the displacement estimation in the(More)
Extrathoracic sclerotic bone involvement of SAPHO syndrome are sometimes very difficult to differentiate from a bone infection or bone tumor. The authors report the case of a 46-year-old patient with a history of palmo-plantar pustulosis, recurrent suppurative hidradenitis, and bilateral sternocostal arthropathy who was evaluated for a sclerotic lesion in(More)
Image segmentation is an important stage in many applications such as image, video and computer processing. Generally image interpretation depends on it. The materials and methods used to demonstrate are described. The results are presented and analyzed. Several approaches and algorithms for image segmentation have been developed, but it is difficult to(More)
This work is a contribution to Adequation between Algorithm and Architecture. It presents an example of application made with SynDEx, a software environment to implement signal processing or automatic algorithms on multiprocessor network. This communication shows that a Conditioned Data Flow Graph used for modelling an algorithm, is enough to do an(More)
The control was performed by a unic systemic autumn treatment on heifers and repeated topical spring treatments on dairy cows. After a four years programme, limited success are obtained. No difference in the efficacy are observed in isolated or grouped farms. A good estimation of infestation cannot be obtained by only one or two numerations of warbles in(More)
