Fast CG-Based Methods for Tikhonov--Phillips Regularization
SIAM Journal on Scientific Computing, 1999The authors study two methods for accelerating the standard conjugate gradient (cg) algorithms for solving a family of systems of the type \[ (A^*A+\alpha I)x= A^* y^\delta. \] In the first method a stopping criterion is developed for the cg-iterates which is linked to the noise level \(\delta\) and the current value of \(\alpha\).

An adaptive Tikhonov regularization method for fluorescence molecular tomography
Medical & Biological Engineering & Computing, 2013The high degree of absorption and scattering of photons propagating through biological tissues makes fluorescence molecular tomography (FMT) reconstruction a severe ill-posed problem and the reconstructed result is susceptible to noise in the measurements.

Tikhonov Regularization Methods for the Inverse Scalp Electroencephalography
Volume 2: Biomedical and Biotechnology Engineering, 2009Electroencephalography (EEG) source localization of brain activity is of high diagnostic value. Noninvasive numerical procedures can be developed to help reconstruct the cortical brain activities from the low-spatial-resolution scalp EEG measurement.

Parameter selection methods for axisymmetric flame tomography through Tikhonov regularization
Applied Optics, 2008Deconvolution of optically collected axisymmetric flame data is equivalent to solving an ill-posed problem subject to severe error amplification. Tikhonov regularization has recently been shown to be well suited for stabilizing this deconvolution, although the success of this method hinges on choosing a suitable regularization parameter.

A Tikhonov Regularization Method for Image Reconstruction
1993Many problems of image reconstruction from projection data have the following mathematical form $$ Am = d $$ (1) where m is the unknown model, d is the observed data and A is a known operator. If A is independent of the model m, the tomographic problem is linear; otherwise it is nonlinear.
