Paper Abstract

Photoacoustic imaging modality is a new biomedical imaging which provides images with high resolution and contrast from different parts of body. In this paper, we have designed a new optical system by using a fiber bundle in order to imaging of a hemorrhage inside of the infant's head. We used Monte Carlo algorithm to simulate light propagation in the infant's head, an acoustic k-space method to simulate photoacoustic signal propagation in it, and time reversal image reconstruction algorithm to get 3D image of the hemorrhage. According to our simulation, this new optical system can provides homogeneous illumination on the infant's head Leads to more accurate images. Furthermore, we have designed and optimized an optical system in order to coupling light from laser source into a fiber bundle with more than 94% efficiency.
