摘要	Ultrasound computed tomography (USCT) has become a promising technique for quantitatively characterizing soft tissues and identifying lesions, particularly in breast cancer detection. The speed of sound (SOS) maps obtained from USCT provide valuable information for this purpose. However, image reconstruction of SOS based on bent ray tracing is an ill-conditioned problem. Enforcing spatial continuity of the slowness map (reciprocal of SOS) which sacrifices spatial resolution can partly overcome this problem, but the reconstruction problem is still discretized and often unstable. In this work, we show that representing the slowness map as a continuous function of spatial coordinates using a multi-layer perceptron (MLP) greatly improves the stability and image quality of the reconstruction. Using the simulated data, the performance of our method is evaluated. © 2023 IEEE.
