Researchers at Martin-Luther-Universität Halle-Wittenberg created realistic 3D-printed skull phantoms that accurately replicate the acoustic properties of human cranial bone, addressing the challenges of transcranial photoacoustic imaging. The optimized phantoms, made using FDM 3D printing, successfully mimicked the acoustic attenuation and wavefront distortion of ex vivo human skulls, particularly above 2 MHz, through precise control of microstructure and porosity.
