Present position：LOUISA-3D Clinical Breast 3D Optoacoustic Imaging System
The LOUSIA-3D system combines the characteristics of high optical imaging contrast and strong acoustic imaging penetration. While obtaining high-resolution tissue images, it can perform high-quality 3D imaging of human breast blood vessels by detecting hemoglobin content. The LOUSIA-3D system study the distribution characteristics of optoacoustic signals in and around different areas of benign and malignant breast lesions, and propose accurate quantitative evaluation methods.
