Journal ArticleDOI
Digimouse: a 3D whole body mouse atlas from CT and cryosection data
TL;DR: A three-dimensional (3D) whole body mouse atlas is constructed from coregistered x-ray CT and cryosection data of a normal nude male mouse and simulations of 3D bioluminescence and PET image reconstruction are included.
Journal ArticleDOI
Iterative reconstruction techniques in emission computed tomography.
Jinyi Qi,Richard M. Leahy +1 more
TL;DR: A review of recent progress in developing statistically based iterative techniques for emission computed tomography describes the different formulations of the emission image reconstruction problem and their properties and describes the numerical algorithms used for optimizing these functions.
Journal ArticleDOI
Resolution and noise properties of MAP reconstruction for fully 3-D PET
Jinyi Qi,Richard M. Leahy +1 more
TL;DR: The authors show that the approximations provide reasonably accurate estimates of contrast recovery and covariance of MAP reconstruction for priors with quadratic energy functions, and describe how these analytical results can be used to achieve near-uniform contrast recovery throughout the reconstructed volume.
Journal ArticleDOI
Recursive MUSIC: A framework for EEG and MEG source localization
John C. Mosher,Richard M. Leahy +1 more
TL;DR: R-MUSIC can easily extract multiple asynchronous dipolar sources that are difficult to find using the original MUSIC scan and is applied to the more general IT model and shows results for combinations of fixed, rotating, and synchronous dipoles.
Journal ArticleDOI
Source localization using recursively applied and projected (RAP) MUSIC
John C. Mosher,Richard M. Leahy +1 more
TL;DR: A new method for source localization is described that is based on a modification of the well-known MUSIC algorithm, and a general form of the RAP-MUSIC algorithm is described for the case of diversely polarized sources.
