KCR approach applied to imaging of a cochlear implant. A) Penalized-likelihood reconstruction at 0.4 mm voxels exhibits substantial artifacts due to inconsistencies arising from NLPV. B) KCR image (with implant position overlaid in red) computed using the variable resolution forward model to overcome NLPV effects (0.4 mm voxels and a 0.1 mm voxel implant model) with true registration parameters known. C) The KCR result using joint estimation of the image and the registration. Both KCR images show greatly reduced NLPV artifacts with subtle residual artifacts in the joint estimation due to registration errors.
