Thalamus Segmentation from Diffusion Tensor Magnetic Resonance Imaging
Thalamus Segmentation Imaging
2009/9/7
We propose a semi-automatic thalamus and thalamus nuclei segmentation algorithm from Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) based on the mean-shift algorithm. Comparing with existing tha...
A Context-Sensitive Active Contour for 2D Corpus Callosum Segmentation
Context-Sensitive 2D Corpus Callosum Segmentation
2009/9/4
We propose a new context-sensitive active contour for 2D corpus callosum segmentation. After a seed contour consisting of interconnected parts is being initialized by the user, each part will start to...
Segmentation of Myocardial Boundaries in Tagged Cardiac MRI Using Active Contours: A Gradient-Based Approach Integrating Texture Analysis
Myocardial Boundaries MRI
2009/9/4
The noninvasive assessment of cardiac function is of first importance for the diagnosis of cardiovascular diseases. Among all medical scanners only a few enables radiologists to evaluate the local car...
Joint Brain Parametric T1-Map Segmentation and RF Inhomogeneity Calibration
Brain Parametric T1-Map Segmentation RF Inhomogeneity Calibration
2009/9/4
We propose a constrained version of Mumford and Shah's (1989) segmentation model with an information-theoretic point of view in order to devise a systematic procedure to segment brain magnetic resonan...
A Novel Segmentation, Mutual Information Network Framework for EEG Analysis of Motor Tasks
Mutual Information Network Framework EEG Analysis Motor Tasks
2010/2/25
Monitoring the functional connectivity between brain regions is becoming increasingly important in elucidating brain functionality in normal and disease states. Current methods of detecting networks i...
A coarse-to-fine approach to prostate boundary segmentation in ultrasound images
prostate boundary segmentation ultrasound images
2010/2/26
A segmentation procedure consisting of four main stages is proposed. In the first stage, a locally adaptive contrast enhancement method is used to generate a well-contrasted image. In the second stage...
