Abstract:This project’s goal is to track deformations and calculate elastographic data using ultrasound imaging on phantoms with a fixed embedded referential. Deformations caused by external pressure and needle insertion could be tracked and visually represented. The proposed algorithms for elastography measurements show effectiveness in global terms but are locally less accurate. The algorithms were tested with homogeneous phantoms, but also using phantoms with heterogeneous compositions. For heterogeneous phantoms, different elastic properties can be perceived, but the Young’s Moduli for the softer regions tend to be overestimated.
