Original Abstract

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.

Ultrazvuková počítačová tomografie je relativně nová zobrazovací modalita, převážně určená pro diagnostiku rakoviny prsu. Objekt se vloží do tanku s vodou, obloženého několika tisíci ultrazvukových měničů. Každý měnič může být použit pro vysílání nebo příjmání uzv vlnění. Utlumové koeficienty objektu jsou odhadnuty z radiofrekvenčního signálu a jsou následně použity pro rekonstrukci obrazu. Tento článek porovnává dvě metody rekonstrukce útlumových obrazů.
