Originální abstrakt

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 ultrasonic waves. Ultrasonic attenuation parameters are estimated from the recorded radiofrequency signals and are then used for tomographic reconstruction of the object. This paper introduces an extension to a recently published novel approach to reconstructing attenuation images. Not only the directly transmitted waves, but also the reflected and refracted ultrasonic waves are used. Thus, a lot more information is incorporated into the reconstruction procedure and the resulting images more resemble the actual distribution of the local attenuation values.
