Test-objects and phantoms for characterization and optimization of hybrid 3D PA-US systems (Conference Presentation)

Paper Abstract

Test-objects for use in hybrid photoacoustic-ultrasound systems with a 3D geometry are introduced. They are designed to assess the system’s spatial resolution, imaging depth and image reconstruction algorithms. Considering the latter, one test-object is designed to test the robustness of algorithms when encountering heterogeneity in sound speeds. A further test-object is designed to test the accuracy of blood oxygenation estimation in image reconstruction. Finally, a novel semi-anthropomorphic photoacoustic-ultrasound breast phantom containing tumors and blood vessels is introduced. This phantom is equipped with adaptable blood oxygenation levels and is a valuable tool for the optimization and characterization of the imaging parameters.
