Paper Abstract

We developed an improved signal and image processing of optoacoustic data collected by our laser optoacoustic imaging system designed for breast cancer detection (LOIS-B). The implemented wavelet-based signal processing allowed significant reduction of the low-frequency acoustic noise, improved contrast and localization of the optoacoustic sources of interest. The system was able to differentiate phantoms mimicking breast tumors based on the contrast and morphology of their images. The implemented wavelet-based signal processing also facilitated high (0.5 mm) resolution of the phantoms mimicking parallel blood vessels in the presence of large-amplitude low-frequency acoustic artifacts. The application of the 3D radial back projection image reconstruction algorithm allowed visulaization of the tumor phantoms located beyond the imaging slice of the arc-shaped array of transducers. The visualization of slices parallel to the array of transducers with individual adjustment of the image palette for each particular slice eliminated the image artifacts caused by the large gradient of the laser fluence orthogonal to the array of transducers.
