FCN Based Label Correction for Multi-Atlas Guided Organ SegmentationSpringer Science and Business Media LLC - Tập 18 - Trang 319-331 - 2020
Hancan Zhu, Ehsan Adeli, Feng Shi, Dinggang Shen
Segmentation of medical images using multiple atlases has recently gained immense attention due to their augmented robustness against variabilities across different subjects. These atlas-based methods typically comprise of three steps: atlas selection, image registration, and finally label fusion. Image registration is one of the core steps in this process, accuracy of which directly affects the f...... hiện toàn bộ
Versatile Morphometric Analysis and Visualization of the Three-Dimensional Structure of NeuronsSpringer Science and Business Media LLC - Tập 11 - Trang 393-403 - 2013
Paulo Aguiar, Mafalda Sousa, Peter Szucs
The computational properties of a neuron are intimately related to its morphology. However, unlike electrophysiological properties, it is not straightforward to collapse the complexity of the three-dimensional (3D) structure into a small set of measurements accurately describing the structural properties. This strong limitation leads to the fact that many studies involving morphology related quest...... hiện toàn bộ
Information-Theoretic Approach for Automated White Matter Fiber Tracts ReconstructionSpringer Science and Business Media LLC - Tập 10 - Trang 305-318 - 2012

Fiber tracking is the most popular technique for creating white matter connectivity maps from diffusion tensor imaging (DTI). This approach requires a seeding process which is challenging because it is not clear how and where the seeds have to be placed. On the other hand, to enhance the interpretation of fiber maps, segmentation and clustering techniques are applied to organize fibers into anatom...... hiện toàn bộ
MDL Constrained 3-D Grayscale Skeletonization Algorithm for Automated Extraction of Dendrites and Spines from Fluorescence Confocal ImagesSpringer Science and Business Media LLC - Tập 7 - Trang 213-232 - 2009
Xiaosong Yuan, Joshua T. Trachtenberg, Steve M. Potter, Badrinath Roysam
This paper presents a method for improved automatic delineation of dendrites and spines from three-dimensional (3-D) images of neurons acquired by confocal or multi-photon fluorescence microscopy. The core advance presented here is a direct grayscale skeletonization algorithm that is constrained by a structural complexity penalty using the minimum description length (MDL) principle, and additional...... hiện toàn bộ
BVAR-Connect: A Variational Bayes Approach to Multi-Subject Vector Autoregressive Models for Inference on Brain Connectivity NetworksSpringer Science and Business Media LLC - Tập 19 - Trang 39-56 - 2020
Jeong Hwan Kook, Kelly A. Vaughn, Dana M. DeMaster, Linda Ewing-Cobbs, Marina Vannucci
In this paper we propose BVAR-connect, a variational inference approach to a Bayesian multi-subject vector autoregressive (VAR) model for inference on effective brain connectivity based on resting-state functional MRI data. The modeling framework uses a Bayesian variable selection approach that flexibly integrates multi-modal data, in particular structural diffusion tensor imaging (DTI) data, into...... hiện toàn bộ
Identifying Multimodal Intermediate Phenotypes Between Genetic Risk Factors and Disease Status in Alzheimer’s DiseaseSpringer Science and Business Media LLC - Tập 14 - Trang 439-452 - 2016

Neuroimaging genetics has attracted growing attention and interest, which is thought to be a powerful strategy to examine the influence of genetic variants (i.e., single nucleotide polymorphisms (SNPs)) on structures or functions of human brain. In recent studies, univariate or multivariate regression analysis methods are typically used to capture the effective associations between genetic variant...... hiện toàn bộ
