Simulation and processing tools for the design and performance evaluation of FMC-TFM techniques

Abstract

Phased array Imaging techniques such as Full Matrix Capture/Total Focusing Method (FMC-TFM) and derived methods are of great interest and are increasingly used as they improve performance in a wide range of situations. In the same way as for conventional Phased Array processes, it is necessary to provide the means to quantify and demonstrate the performance of a control. This involves relying on new criteria, being able to demonstrate their reliability and assessing the sensitivity of the different parameters. In this paper, we present the potential of simulation and post-processing tools to address these issues. Indeed many alternatives are possible, whether in acquisition techniques (FMC, Perfusion Weighted Image, Air Traffic Flow Management), or processing possibilities (artifact filters, imaging modes, signal processing). This communication is based on the use of the CIVA simulation and analysis platform, whose recent advances make it possible to accurately assess the sensitivity of all the parameters of a control based on the FMC-TFM technology either at the level of the control method (probe, positioning, geometry, material characteristics ...) or the data processing which is possible to personalize it through a new python plug-in solution accessible to all.
