An integrative systems biology approach for analyzing liver hypermetabolism
hypermetabolism gene expression regulation
2009/12/24
Severe injury and other disease conditions (cancer, diabetes) lead to a hypermetabolic
state featuring increased turnover of proteins, fatty acids and carbohydrates. Prolonged
hypermetabolism is a...
Comprehensive approach for motion and distortion correction in diffusion weighted MRI
Comprehensive approach motion and distortion correction diffusion weighted MRI

Comprehensive approach for motion and distortion correction in diffusion weighted MRI.
An Integrated Approach to Medical Robotics and Computer Assisted Surgery in Orthopaedics
Medical Robotics Computer Assisted Surgery Orthopaedics
2009/12/22
There is great potential for medical robotics to have a positive impact upon surgical techniques, panicularly in orthopaedics. Joint replacement procedures occur frequently, are very expensive, and de...
A General Local Reconstruction Approach Based on a Truncated Hilbert Transform
A General Local Reconstruction Approach Truncated Hilbert Transform
2009/9/7
Exact image reconstruction from limited projection data has been a central topic in the computed tomography (CT) field. In this paper, we present a general region-of-interest/volume-of-interest (ROI/V...
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...
Novel Approach Combining Experiment and Simulation to Clarify the Mechanisms of Stretch-induced Arrhythmias
mechano-electric feedback stretch-activated channels optical mapping heart simulation spiral wave
2009/8/24
Mechanical stress is known to alter the electrophysiological property of myocardium and may trigger fatal arrhythmias when an abnormal load is applied to the heart. We developed novel techniques combi...
Growth rate and rupture rate of unruptured intracranial aneurysms: a population approach
Growth rate rupture rate unruptured intracranial aneurysms
2010/2/25
This mathematical model can be used to predict aneurysm growth rate, and the results are consistent with previous clinical studies. Predictions from both hypothetical and clinical cases agree very wel...
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...
