Original Abstract

In breast cancer diagnosis, standard ultrasound B-mode examination provides useful additional diagnostic information. However, interpretation of ultrasound images is very difficult because of poor spatial resolution, low contrast and the presence of speckles. In breast-tissue imaging, ultrasound transmission tomography is an alternative with potentially higher image quality. Although it has been researched for several decades, so far it has not been developed to a clinically applicable state. In this contribution, the current state of our research in attenuation imaging using ultrasound transmission tomography is described.

Czech abstract

Standardní ultrazvukové zobrazení v B-módu je dnes dodatečnou zobrazovací metodou v diagnostice rakoviny prsu. Interpretace zobrazovaných struktur je zde obtížná v důsledku nízké prostorové rozlišovací schopnosti, nízkému kontrastu a přítomnosti strukturního šumu, tzv. speklí. Průzvučná ultrazvuková tomografie může být v mamografii alternativou k zobrazení v B-módu, s potenciálně vyšší kvalitou obrazu v důsledku snímání objektu z mnoha stran. Tento příspěvek popisuje současný stav našeho projektu zobrazování útlumových map pomocí této modality.
