Outline of Final Research Achievements

Photoacoustic imaging is a medical imaging technology that offers high contrast images of blood vessels in biological tissue.　Photoacoustic imaging system consists of an ultrasound imaging device and a pulsed light source. The purpose of this research was to develop a method to measure blood oxygen saturation of blood vessels in biological tissues non-invasively and continuously. A photoacoustic signal analysis method to measure blood oxygen saturation accurately was proposed. Furthermore, an imaging system to offer blood oxygen saturation mapping was developed.
