Chemotherapy, estrogen, and cognition : neuroimaging and genetic variation
Chemotherapy estrogen cognition neuroimaging genetic variation
2015/5/21
The time course and biological mechanisms by which breast cancer (BC) and/or alterations in estrogen status lead to cognitive and brain changes remain unclear. The studies presented here use neuroimag...
Semi-automatic algorithm for construction of the left ventricular area variation curve over a complete cardiac cycle
Semi-automatic algorithm the left ventricular area a complete cardiac cycle
2010/2/25
This work presents a method for segmentation of the left ventricle in dynamic 2D-echo 4-chamber long-axis images over the complete cardiac cycle. The proposed algorithm is based on classic image proce...

Deformation-based nuclear morphometry: Capturing nuclear shape variation in HeLa cells.
We propose a denoising algorithm for medical images based on a combination of the total variation minimization scheme and the wavelet scheme. We show that our scheme offers effective noise removal i...
Total Variation Regularization of Matrix-Valued Images
Total Variation Regularization Matrix-Valued Images
2009/9/7
We generalize the total variation restoration model, introduced by Rudin, Osher, and Fatemi in 1992, to matrix-valued data, in particular, to diffusion tensor images (DTIs). Our model is a natural ext...
Suppression of MRI Truncation Artifacts Using Total Variation Constrained Data Extrapolation
Variation Constrained Data Extrapolation MRI
2009/9/4
The finite sampling of k-space in MRI causes spurious image artifacts, known as Gibbs ringing, which result from signal truncation at the border of k-space. The effect is especially visible for acquis...
Unrestrained Facile Measurement of Narrow-band ECG and Respiratory Variation in Infants with a Capacitive Sheet-type Sensor
capacitive sensing non-intrusive monitoring capacitive electrode ECG monitoring respiration
2009/8/24
We propose a new method for obtaining narrow-band electrocardiographic potential (ECG) and respiratory variation in infants through their underwear. This method is based on capacitive coupling involvi...
Genetic Variation in ATP7B Promotor and 5' UTR in Han Chinese Patients with Wilson's Disease
Wilson's disease copper the ATP7B gene promoter metal response elements
2009/3/16
Wilson's disease (WD) is an autosomal recessive disorder of copper transport characterized by the accumulation of intracellular copper in the liver and extrahepatic tissues. The WD gene (ATP7B) encode...
Influence on fluid dynamics of coronary artery outlet angle variation in artificial aortic root prosthesis
fluid dynamics coronary artery outlet angle variation artificial aortic root prosthesis
2010/2/25
Two simplified base geometries are used for simulating the blood flow in order to determine velocity and pressure distributions. One model uses a straight cylindrical tube to approximate the aortic ro...
