Cross-View Neuroimage Pattern Analysis in Alzheimer's Disease Staging.

Frontiers in aging neuroscience

Liu S, Cai W, Pujol S, Kikinis R, Feng DD.
PMID: 26941639
Front Aging Neurosci. 2016 Feb 23;8:23. doi: 10.3389/fnagi.2016.00023. eCollection 2016.

The research on staging of pre-symptomatic and prodromal phase of neurological disorders, e.g., Alzheimer's disease (AD), is essential for prevention of dementia. New strategies for AD staging with a focus on early detection, are demanded to optimize potential efficacy...

Sheet Probability Index (SPI): Characterizing the geometrical organization of the white matter with diffusion MRI.

NeuroImage

Tax CMW, Dela Haije T, Fuster A, Westin CF, Viergever MA, Florack L, Leemans A.
PMID: 27456538
Neuroimage. 2016 Nov 15;142:260-279. doi: 10.1016/j.neuroimage.2016.07.042. Epub 2016 Jul 25.

The question whether our brain pathways adhere to a geometric grid structure has been a popular topic of debate in the diffusion imaging and neuroscience societies. Wedeen et al. (2012a, b) proposed that the brain's white matter is organized...

A Kalman Filtering Perspective for Multiatlas Segmentation.

SIAM journal on imaging sciences

Gao Y, Zhu L, Cates J, MacLeod RS, Bouix S, Tannenbaum A.
PMID: 26807162
SIAM J Imaging Sci. 2015;8(2):1007-1029. doi: 10.1137/130933423. Epub 2015 Apr 30.

In multiatlas segmentation, one typically registers several atlases to the novel image, and their respective segmented label images are transformed and fused to form the final segmentation. In this work, we provide a new dynamical system perspective for multiatlas...

Interpolation of Longitudinal Shape and Image Data via Optimal Mass Transport.

Proceedings of SPIE--the International Society for Optical Engineering

Gao Y, Zhu LJ, Bouix S, Tannenbaum A.
PMID: 25302008
Proc SPIE Int Soc Opt Eng. 2014 Mar 21;9034:90342X. doi: 10.1117/12.2043282.

Longitudinal analysis of medical imaging data has become central to the study of many disorders. Unfortunately, various constraints (study design, patient availability, technological limitations) restrict the acquisition of data to only a few time points, limiting the study of...

Reconstruction and Feature Selection for Desorption Electrospray Ionization Mass Spectroscopy Imagery.

Proceedings of SPIE--the International Society for Optical Engineering

Gao Y, Zhu L, Norton I, Agar NY, Tannenbaum A.
PMID: 25302009
Proc SPIE Int Soc Opt Eng. 2014 Mar 12;9036:90360D. doi: 10.1117/12.2043273.

Desorption electrospray ionization mass spectrometry (DESI-MS) provides a highly sensitive imaging technique for differentiating normal and cancerous tissue at the molecular level. This can be very useful, especially under intra-operative conditions where the surgeon has to make crucial decision...

Automated dispersion and orientation analysis for carbon nanotube reinforced polymer composites.

Nanotechnology

Gao Y, Li Z, Lin Z, Zhu L, Tannenbaum A, Bouix S, Wong CP.
PMID: 23060008
Nanotechnology. 2012 Nov 02;23(43):435706. doi: 10.1088/0957-4484/23/43/435706. Epub 2012 Oct 11.

The properties of carbon nanotube (CNT)/polymer composites are strongly dependent on the dispersion and orientation of CNTs in the host matrix. Quantification of the dispersion and orientation of CNTs by means of microstructure observation and image analysis has been...

DIFFEOMORPHIC POINT SET REGISTRATION USING NON-STATIONARY MIXTURE MODELS.

Proceedings. IEEE International Symposium on Biomedical Imaging

Wassermann D, Ross J, Washko G, Westin CF, Estépar RS.
PMID: 24419463
Proc IEEE Int Symp Biomed Imaging. 2013; doi: 10.1109/ISBI.2013.6556656.

This paper investigates a diffeomorphic point-set registration based on non-stationary mixture models. The goal is to improve the non-linear registration of anatomical structures by representing each point as a general non-stationary kernel that provides information about the shape of...

Deep white matter analysis: fast, consistent tractography segmentation across populations and dMRI acquisitions.

Medical image computing and computer-assisted intervention : MICCAI ... International Conference on Medical Image Computing and Computer-Assisted Intervention

Zhang F, Hoffmann N, Karayumak SC, Rathi Y, Golby AJ, O'Donnell LJ.
PMID: 32558816
Med Image Comput Comput Assist Interv. 2019 Oct;11766:599-608. doi: 10.1007/978-3-030-32248-9_67. Epub 2019 Oct 10.

We present a deep learning tractography segmentation method that allows fast and consistent white matter fiber tract identification across healthy and disease populations and across multiple diffusion MRI (dMRI) acquisitions. We create a large-scale training tractography dataset of 1...

Histogram analysis of tensor-valued diffusion MRI in meningiomas: Relation to consistency, histological grade and type.

NeuroImage. Clinical
