Tomography across scales: Knowledge transfer from seismology to imaging breast tissue with ultrasound

Autor: Korta Martiartu, Naiara

Wave propagation is extensively used to understand the internal structure of media that are not accessible to direct observations. Seismology and medical ultrasound imaging are good examples of this. The former uses observations of seismic waves at t
