Echocardiogram enhancement using supervised manifold denoising.
Medical image analysis
May 21, 2015
This paper presents data-driven methods for echocardiogram enhancement. Existing denoising algorithms typically rely on a single noise model, and do not generalize to the composite noise sources typically found in real-world echocardiograms. Our meth...
Automated extraction and labelling of the arterial tree from whole-body MRA data.
Medical image analysis
May 21, 2015
In this work, we present a fully automated algorithm for extraction of the 3D arterial tree and labelling the tree segments from whole-body magnetic resonance angiography (WB-MRA) sequences. The algorithm developed consists of two core parts (i) 3D v...
Efficient multi-atlas abdominal segmentation on clinically acquired CT with SIMPLE context learning.
Medical image analysis
May 21, 2015
Abdominal segmentation on clinically acquired computed tomography (CT) has been a challenging problem given the inter-subject variance of human abdomens and complex 3-D relationships among organs. Multi-atlas segmentation (MAS) provides a potentially...
Multi-class BCGA-ELM based classifier that identifies biomarkers associated with hallmarks of cancer.
BMC bioinformatics
May 20, 2015
BACKGROUND: Traditional cancer treatments have centered on cytotoxic drugs and general purpose chemotherapy that may not be tailored to treat specific cancers. Identification of molecular markers that are related to different types of cancers might l...
MR image synthesis by contrast learning on neighborhood ensembles.
Medical image analysis
May 18, 2015
Automatic processing of magnetic resonance images is a vital part of neuroscience research. Yet even the best and most widely used medical image processing methods will not produce consistent results when their input images are acquired with differen...
Automating the generation of lexical patterns for processing free text in clinical documents.
Journal of the American Medical Informatics Association : JAMIA
May 14, 2015
OBJECTIVE: Many tasks in natural language processing utilize lexical pattern-matching techniques, including information extraction (IE), negation identification, and syntactic parsing. However, it is generally difficult to derive patterns that achiev...
A hybrid method for airway segmentation and automated measurement of bronchial wall thickness on CT.
Medical image analysis
May 14, 2015
Inflammatory and infectious lung diseases commonly involve bronchial airway structures and morphology, and these abnormalities are often analyzed non-invasively through high resolution computed tomography (CT) scans. Assessing airway wall surfaces an...
KnowLife: a versatile approach for constructing a large knowledge graph for biomedical sciences.
BMC bioinformatics
May 14, 2015
BACKGROUND: Biomedical knowledge bases (KB's) have become important assets in life sciences. Prior work on KB construction has three major limitations. First, most biomedical KBs are manually built and curated, and cannot keep up with the rate at whi...
A Projection Neural Network for Constrained Quadratic Minimax Optimization.
IEEE transactions on neural networks and learning systems
May 7, 2015
This paper presents a projection neural network described by a dynamic system for solving constrained quadratic minimax programming problems. Sufficient conditions based on a linear matrix inequality are provided for global convergence of the propose...
Deep convolutional neural networks for annotating gene expression patterns in the mouse brain.
BMC bioinformatics
May 7, 2015
BACKGROUND: Profiling gene expression in brain structures at various spatial and temporal scales is essential to understanding how genes regulate the development of brain structures. The Allen Developing Mouse Brain Atlas provides high-resolution 3-D...
