- W2996266676 abstract "A fundamental assumption in traditional photoacoustic computed tomography (PACT) reconstruction methods is that the medium is acoustically homogeneous. However, this assumption is often inconsistent with reality. Seismic migration imaging based on the exploding reflector model (ERM) has many similarities with photoacoustic imaging principles, and there exist valuable references in reconstruction strategies. In this paper, Stolt's F-K Migration technique is introduced to reconstruct photoacoustic images. Furthermore, in order to solve the non-uniform speed of sound (SOS) problem in the practical application of PACT, we utilized the Margrave's strategy in seismic imaging which considers the change of arbitrary vertical SOS in the object to be measured for reference, and we proposed a PACT reconstruction approach based on prior SOS. Moreover, k-Wave toolbox was used for performance comparison via simulation, and the reconstruction results of point sources and vascular network model show that F-K method based on prior SOS has better reconstruction performance than traditional FFT method." @default.
