Abstract :
We applied photoacoustics for noninvasive two-dimensional imaging of blood vessels in vivo, using near infrared light. This study was undertaken to develop photoacoustic tomography of tissue for the detection of embedded blood vessels using a newly developed piezoelectric double ring detector, featuring an extremely narrow aperture.
