MUSA-WAVE: A Software Platform for Magnetomotive Ultrasound and Shear Wave Analysis

Ultrasound imaging techniques employing induced particle displacement or particle velocity have several biomedical applications due to their capacity to estimate the mechanical properties of tissues. These methods are valuable, for example, in shear wave elastography and magnetomotive ultrasound. Important steps include estimating particle displacement maps, filtering, and post-processing to accurately estimate stiffness in elastography-based techniques, analyze the behavior of magnetic nanoparticles in magnetomotive ultrasound, and estimate viscoelastic parameters of materials. In this paper, a software platform designed for processing ultrasound data, estimating displacement maps, and analyzing shear wave group and phase velocity are described. It comprises some of the most used algorithms available in the literature for processing ultrasound radiofrequency data. The platform's features were described, and examples of its applications in acoustic radiation force and magnetomotive ultrasound were demonstrated.
