Three-dimensional time-domain waveform inversion for breast ultrasound tomographyMS77

Ultrasound computed tomography (USCT) is a promising medical imaging modality that offers several novel tissue contrasts and holds great potential for breast cancer screening. Waveform inversion-based image reconstruction methods account for higher order diffraction effects and can produce high-resolution USCT images. However, many USCT studies have assumed a 2D imaging model, which can result in image artifacts in practice. In this work, a waveform inversion method for 3D USCT is reported.
