Endoscopy is a standard imaging modality commonly used in different medical fields like lesion diagnosis in hollow organs or mini-invasive surgery. Meanwhile, endoscopic data suffer from the fact that each image of a video-sequence only corresponds to a small 2D field of view. This paper presents a mosaicing algorithm leading to visually coherent large field of view maps. The ability of the algorithm...
The purpose of this work is to compute several image processing techniques, applied to US images of HIFU-induced lesions, to characterize the shape, contour, position and the orientation of thermal lesions. In order to obtain real-time monitoring of HIFU treatment, a B-mode US imaging system and HIFU were synchronized. First, the HIFU sonication procedure consisted of applying an initial power of...
The analysis of the ECG signal is widely used for detecting a variety of cardiac pathologies. Most of the clinically useful information embedded in the ECG is related to the duration and amplitude of its individual components. Producing algorithms for the automatic extraction of the ECG features is complicated due to the time-varying nature of the signal resulting of variable physiological conditions...
