Abstract

Computed ultrasound tomography in echo mode (CUTE) uses handheld pulse-echo ultrasound to image the spatial distribution of speed-of-sound. For a specific application of CUTE, the quantification of the fat fraction in the liver, convex probes are preferred to capture a large area of the liver in a sector scan. We demonstrate the adaptation of CUTE for such convex probes, showing phantom as well as in vivo results. We also discuss ideas of how to make use of the specific geometry of a convex probe in order to make such an implementation computationally efficient, and highlight the specific challenges when using convex compared to linear probes.
