| Popis: | Monolithic integration of stereovision can make a contribution in today's solutions where main limitations are size, power consumption and deployment. Some emergent applications are not equipped with 3D capabilities although the demand is increasing. One of these applications is 3D-endoscopy which claims good accuracy, small volume, and high autonomy in terms of power consumption and operation. Integrated stereovision used in the medical world and especially for the diagnosis of pathologies of the digestive tract gives an additional advantage for the gastro-enterologists in the observation of malignant tumors. In 3D endoscopy, integrated stereovision satisfies four essential needs: Firstly, precision of diagnosis is required, more exactly the accuracy in the evaluation of the carcinoma size. Without a real 3D representation, estimations are done roughly due to the lack of information (depth parameter) and are defined by the experience of the expert rather than by the system itself. At the present time only an invasive exploration allows an exact location and measurement of tumor size. Secondly, integrated stereovision meets a growing public need. Improvement in healthcare provides to the population some well-being and people live longer. The diagnosis of early forms of cancer of the digestive tract takes part in the well-being of aged people: the sooner a sick person is treated, the earlier he can recover. In the case of endoscopy, the French Company of Digestive Endoscopy (SFED) stresses in 2006 that the use of endoscopy is increasing: 2.7 million examinations were carried out, 70000 new digestive cancers were discovered and almost 900000 polyps colics were removed. Various types of endoscopy (E.O.G.D, Coloscopy, enteroscopy…) give only planar vision of the digestive tract. The contribution of the 3rd dimension would be an important advantage in the diagnosis of pathology. Thirdly, integrated stereovision also meets a need for freedom: freedom of movement, freedom to be at home and not in a hospital. The patient swallows the capsule and he can go back to his activities. Optimization of the dimension of the capsule, autonomous operation and long battery life of the sensor are essential constraints. |
