A nested optimization framework for sound speed imaging and uncertainty estimation in ultrasound computed tomography via Mamba-regularized full waveform inversion.

Full-waveform inversion (FWI) for ultrasound computed tomography (USCT) has recently been investigated extensively for high-resolution sound-speed (SS) imaging. However, the nonconvexity of FWI hampers global convergence, yielding limited robustness and artifacts that constrain clinical applicability. Existing methods...

Multidimensional Quality Evaluation of Imaging Performance for Musculoskeletal Ultrasound Computed Tomography System

Core parameters of the Musculoskeletal Ultrasound Computed Tomography System (MUCTS), such as spatial resolution, slice thickness, and three-dimensional reconstruction volume error, directly determine imaging performance and clinical diagnostic accuracy. To objectively and systematically assess the imaging quality and...
