Abstract

Ultrasound bent-ray tomography can produce the sound-speed distribution of the breast for detection and diagnosis of breast cancer. However, the conventional ultrasound ray tomography uses only transmission data, leading to low-resolution images. We develop a new ultrasound bent-ray tomography technique using both transmission and reflection data to improve sound-speed reconstructions. We employ an ultrasound reflection imaging technique, Kirchhoff migration, to obtain the locations of reflectors for calculating arrival times of ultrasound refection signals. We use both first-arrival times (time-of-flights) of ultrasound transmission data and arrival times of ultrasound reflection data for sound-speed reconstructions. Our numerical studies show that our new ultrasound bent-ray tomography using both transmission and reflection data significantly improves the image resolution and sound-speed reconstructions compared to the conventional ultrasound ray tomography using only transmission data.
