Anotace:

Ultrasonic Computed Tomography (USCT) is a relatively new imaging modality primarily aimed at breast cancer diagnosis. The examined object is placed in a tank, covered with several thousands of ultrasonic transducers. Each of these transducers is used for emitting and receiving radiofrequency signals, which are then used for tomographic reconstruction of the object. This paper focuses on ultrasonic attenuation imaging. Two approaches to estimating the ultrasonic attenuation coefficients are described and the reconstructed attenuation images are presented.
