VILSS: Ultrasound imaging and inverse problems

Denis Kouame, Universite Paul Sabatier Toulouse

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), or Computed Tomography (CT), ultrasound images suffers from the presence of speckle and have low-resolution in most standard applications. Although most 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 basics and advanced ultrasound imaging, then we will focus on the current signal and image processing challenges, and show some recent results.
