Abstract

A new hybrid method that is based on the interaction of ultrasound and magnetic field has been developed for breast tumor detection. This method is capable to assess the acoustic and electric properties of Normal and pathological breast tissue for characterization. In this study, the acoustic attenuation of Normal and pathological mice breast tissue has been investigated from the ultrasound signal that is captured and recorded by the hybrid magnetoacoustic system. A total of 8 Normal and 10 pathological mice breast tissue samples were studied by using a 10MHz ultrasound wave in transmission mode. The result of the attenuation measurement shows that pathological tissues attenuate more ultrasound compared to Normal tissue. These results also agrees very well with previous research finding that indicates attenuation is lower for tissue with high proportion of cells such as mammary gland and fatty tissue and increases with collagen fibre content since the pathological tissue that were used in this study is multifocal, highly fibrotic and inVol.ve the entire mammary fat pad.
