Journal ArticleDOI
An equal start: absence of group differences in cognitive, social, and neural measures prior to music or sports training in children
Assal Habibi,Beatriz Ilari,Kevin Crimi,Michael J. Metke,Jonas T. Kaplan,Anand A. Joshi,Richard M. Leahy,David W. Shattuck,So Y. Choi,Justin P. Haldar,Bronte Ficek,Antonio R. Damasio,Hanna Damasio +12 more
TL;DR: A longitudinal investigation of the effects of childhood music training on cognitive, social and neural development found no neural, cognitive, motor, emotional, or social differences among the three groups and found no correlation between music perception skills and any of the social or emotional measures.
Journal ArticleDOI
Global point signature for shape analysis of carpal bones.
Abhijit J. Chaudhari,Richard M. Leahy,Barton L Wise,Nancy E Lane,Ramsey D. Badawi,Anand A. Joshi +5 more
TL;DR: The utility of the proposed GPS representation is demonstrated to provide a means for comparing shapes of the carpal bones across populations and to employ a metric that exploits the scale and isometric invariance of eigenfunctions to quantify overall bone shape.
Journal ArticleDOI
Internet2-based 3D PET image reconstruction using a PC cluster.
TL;DR: An approach to fast iterative reconstruction from fully three-dimensional (3D) PET data using a network of PentiumIII PCs configured as a Beowulf cluster is described and a browser-based interface is developed using Java to facilitate the use of this system.
Journal ArticleDOI
Information theoretic regularization in diffuse optical tomography
C. Panagiotou,Sangeetha Somayajula,Adam Gibson,Martin Schweiger,Richard M. Leahy,Simon R. Arridge +5 more
TL;DR: In this article, the authors examined the possibility of regularizing diffuse optical tomography via the introduction of a priori information from alternative high-resolution anatomical modalities, using the information theory concepts of mutual information (MI) and joint entropy (JE).
Journal ArticleDOI
Excitation spectroscopy in multispectral optical fluorescence tomography: methodology, feasibility and computer simulation studies
Abhijit J. Chaudhari,Sangtae Ahn,Richard M. Levenson,Ramsey D. Badawi,Simon R. Cherry,Richard M. Leahy +5 more
TL;DR: A linear algebraic formulation of the multiple wavelength illumination-multispectral detection forward model for OFT is described and the performance of the method for 3D reconstruction of tumors in a simulated mouse model of metastatic human hepatocellular carcinoma is demonstrated.
