| Abstract: | Photoacoustic(PA) effect,which is the theoretical basis of PA imaging,is presented.Based on this theory,some PA imaging technologies are introduced,which are used in non-focused transducer detection mode.Some main imaging algorithms in this field are discussed,including inverse 3-D Radon transform,filtered back-projection as well as P-transform reconstruction algorithms. |
