Several methods have been used for imaging soft tissue, tumors (especially cancerous tumor) and similar structure. One of the newest methods is photoacoustic imaging in which the tissue is illuminated by an appropriate laser pulse and the produced acoustic wave resulting from thermal expansion of the tissue is recorded. In this paper, this technique is simulated for a tumor inside the brain, and the effect of its size, depth and the thickness of the skull on the recorded acoustic wave by the finite element time domain method are investigated.
