Description
Summary:Compared to other medical breast imaging techniques, ultrasonic imaging is more attractive due to its relatively low cost and wide clinical use. This study is concerned with clinical amplitude/velocity reconstruction imaging (CARI) ultrasonography for accurately detecting breast cancer using two acoustic properties: the sound speed and the attenuation. Bioacoustic modeling is used to describe ultrasound wave propagation in the breast/tumor system. The feasibility and the sensitivity of the CARI device are investigated using a finite-element time-domain approximation in tissue-mimicking breast. 2D and 3D simulation experiments show the detectability of small ellipse/ellipsoid-shaped tumors in terms of the increase in the sound speed in the tumor region. Our study confirms also that the FETD (finite-element time domain) method is a simple but robust tool to simulate the CARI device and other included clinical effects, such as focusing and scanning of the beams.
