The theoretical framework I presented
in Biondi (2010)
can be extended from transmission-tomography problems
to MVA problems.
The computational cost of the proposed method can be high,
though the cost of one iteration is comparable
with the cost of one iteration of full waveform inversion.
Numerical tests of the gradient operator and
of the complete velocity-estimation method are needed.
