Abstract

Ultrasound tomography would allow ultrasound imaging to reach its full potential, compared to X-ray, MRI, etc. It is based on inverse scattering and has the capability to detect structures whose sizes are smaller than the wavelength of the incident wave, as opposed to conventional one using pulse-echo technique. Some material properties such as sound contrast and attenuation are very useful to detect small objects. The Distorted Born Iterative Method (DBIM) based on first-order Born approximation is an efficient diffraction tomography approach. The compressed sensing technique is utilized for the DBIM to obtain the high-quality ultrasound image. However, the image reconstruction process is quite long. In this paper, we proposed an approach to enhance the imaging quality and to reduce the imaging time by applying the compressed sensing technique along with the multi-resolution technique for the DBIM. The simulation results indicate that the imaging time is 33% reduced, the imaging quality is 83% improved.
