Název v původním jazyce

Ultrasonic Attenuation Tomography Based on Log-Spectrum Analysis

Popis výsledku v původním jazyce

The paper presents a new ultrasonic attenuation imaging method which might be used as a new imaging modality, targeted at breast cancer diagnostics. Two approaches based on ultrasonic imaging are combined together, namely the estimation of ultrasound attenuation coe cients from pulse{echo B{mode imaging data and an ultrasound computer tomography imaging technique. A recently published method for estimation of the ultrasound attenuation coe cient using the log{spectrum analysis is applied to radiofrequenncy signals acquired by an ultrasound computer tomography system to estimate images of the attenuation coe cients. The examined volume (e.g. female breast) is enclosed by several thousand ultrasound transducers. Radiofrequency signals from all transducers using all sending positions are recorded. Compared to the known ultrasound attenuation tomography methods, not only the directly transmitted signal, but also the re ected and scattered signals are processed here, i.e. substantially more
