Ultrasound Computed Tomography (USCT) is an imaging method to map acoustic properties in soft tissues, e. g., for the diagnosis of breast cancer. A group of USCT methods rely on a passive reflector behind the imaged tissue, and they function by delineating such reflector in echo traces, e.g., to infer time-of- flight measurements for reconstructing local speed-of-sound maps. In this work, we study various echo features and delineation methods to robustly identify reflector profiles in echos. We compared and evaluated the methods on a multi-static data set o f a realistic breast phantom. Based on our results, a RANSAC based outlier removal followed by an active contours based delineation using a new " edge" feature we propose that detects the first arrival times of echo performs robustly even in complex media; in particular 2.1 times superior to alternative approaches at locations where diffraction effects are prominent. |
