Objective image alignment for three-dimensional reconstruction of digital autoradiograms
TL;DR: Two independent algorithms for coronal image alignment that have been successfully implemented in computer programs are reported, and a quantitative assessment of the registration of non-identical images is considered.
Journal ArticleDOI
Clinical evaluation of chirp-coded excitation in medical ultrasound
TL;DR: Coded excitation using frequency-modulated US signals gives improved image quality and provides increased penetration in medical US imaging, and can be used to allow imaging at higher frequencies and thereby increase spatial resolution without any loss of penetration.

Galaxy-Scale Strong-Lensing Tests of Gravity and Geometric Cosmology: Constraints and Systematic Limitations
TL;DR: In this article, the authors combine data on 53 galaxy-scale strong lenses from the Sloan Lens ACS Survey with a well-motivated fiducial set of lens-galaxy parameters to find a constraint on the post-Newtonian parameter γ = 1.01 ± 0.05.

Foundations of MRI phase imaging and processing for Quantitative Susceptibility Mapping (QSM)
TL;DR: Starting with the fundamental relation between MRI signal and tissue magnetic susceptibility this review covers the reconstruction of magnetic field maps from multi-channel phase images, background field correction, and provides an overview of state of the art QSM solution strategies.
