Signal and image processing challenges in medical ultrasound imaging
Professor Denis Kouamé
Description
Among all the medical imaging modalities, ultrasound imaging is the most widely used, due to its safety, cost-effectiveness, flexibility and real-time nature. However, compared to other medical imaging modalities such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT), ultrasound images suffers from the presence of speckle and have low-resolution in most of standard applications. Although most of manufacturers of ultrasound scanners have developed many device-based-routines in order to overcome these issues, many challenges in terms of signal and image processing remain. In this tutorial, we will review the basic and advanced ultrasound imaging, then we will focus on the current signal and image processing challenges, and show some recent results.
Biography
Professor Denis Kouamé has been with University Paul Sabatier, Toulouse, France, since 2008, where he is the head of the Health Information Technology research activity at IRIT (Computer Science Labs). From 1998 to 2008, he was associate professor at the University of Tours France, where he was head of ultrasound imaging group at Ultrasound Lab (LUSSI). From 1996 to 1998 he was senior engineer at Ultrasound division at university of Tours (GIP ultrasound), Tours, France. He received the Master degree in Automatic control and computer science, the PhD in signal processing and ultrasound imaging from the University of Tours, Tours, France in 1993 and 1996, respectively. His research interests are focused on Signal and Image processing with applications to medical imaging and particularly ultrasound imaging, including high resolution imaging, image resolution enhancement, Doppler signal processing, Detection and estimation with application to cerebral emboli detection, multidimensional parametric modeling, spectral analysis, Inverse problems related to compressed sensing and restoration. He led and still leads many multidisciplinary university research initiatives and French or European research founding projects dealing with signal and image processing in ultrasound imaging. He has also led a number of invited conferences, special sessions and tutorials in this area at several IEEE conferences and workshops. He has been and is still member of various French and international research projects evaluation committees. Prof Kouamé is an associate editor of the IEEE Transactions on Ultrasound Ferroelectrics and Frequency control (TUFFC)
