Development of Photoacoustic System for Breast Cancer Detection

Abstract

Recently, the photoacoustic imaging system has been widely and intensively developed, and has been shownthe possibility of diagnosis for early stage cancer. In this study, we developed a photoacoustic tomographyimaging system with a commercial ultra sound device and a linear array probe. A tube phantom and a chickenbreast phantom was made for the possibility of a system as a breast cancer detection. A moving average filterand a band pass filter with 3∼6 MHz bandwidth were developed for background noise elimination beforedelay-and-sum beamforming algorithm was used for image reconstruction. As a result, we showed that somesignal processing procedure before beamforming was effective for the photoacoustic image reconstruction.
