Variational Iterative Algorithms in Photoacoustic Tomography with Variable Sound Speed
Variational Iterative Algorithms Photoacoustic Tomography
2014/9/26
In this paper, we investigate the adjoint equation in photoacoustic tomography with
variable sound speed, and propose three variational iterative algorithms. The basic
idea of these algorithms is to...
