Abstract

Photoacoustic imaging (PAI) has proved to be a promising non-invasive technique for diagnosis, prognosis and treatment monitoring of neurological disorders in small and large animals. The conventional illumination method for photoacoustic is a called top-illumination were diffused light hit the target from one side. However, this method is not suitable for all target shapes and body parts like breast. To overcome this problem we proposed a novel side-illumination scheme where light comes from a set of fibers all around the object. We showed that this method can improve the obtained images with phantom experiments and simulations. This method is particularly useful for in-plane imaging where the ring of fibers scan long objects.
