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...
Blind Deblurring Reconstruction Technique with Applications in PET Imaging
PET Imaging Blind Deblurring Reconstruction Technique
2009/9/4
We developed an empirical PET model taking into account system blurring and a blind iterative reconstruction scheme that estimates both the actual image and the point spread function of the system. Re...
Elastography Method for Reconstruction of Nonlinear Breast Tissue Properties
Elastography Method Nonlinear Breast Tissue Properties
2009/9/4
Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. In this paper a nonlinear elastography method is introduced for recons...
Thermal properties of biological tissues play a critical role in the study of tumor angiogenesis and the design and monitoring of thermal therapies. To map thermal parameters noninvasively, we propose...

Time-Domain EPR
2009/9/4
Three-dimensional Oximetric Electron Paramagnetic Resonance Imaging using the Single Point Imaging modality generates unpaired spin density and oxygen images that can readily distinguish between norma...
Mjolnir: Extending HAMMER Using a Diffusion Transformation Model and Histogram Equalization for Deformable Image Registration
Histogram Equalization Deformable Image Registration
2009/9/4
Image registration is a crucial step in many medical image analysis procedures such as image fusion, surgical planning, segmentation and labeling, and shape comparison in population or longitudinal st...
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...
Currently, 3D cone-beam CT image reconstruction speed is still a severe limitation for clinical application. The computational power of modern graphics processing units (GPUs) has been harnessed to pr...
The Development of the Magnetic Sensor for Detecting the Residual Brain Tumor: Optimal Dosage and Safety of Magnetic Cationic Liposome
magnetite cationic liposome cerebral tumor image-guided neurosurgery magnetic sensor
2009/8/24
We developed a new magnetic sensor for residual brain tumor using magnetite enveloped by cationic liposome (MCL) . First, we evaluated the dynamic state of MCL on MRI following local injection into th...

Computer aided surgery range of motion limb length difference surgical simulation total hip replacement
2009/8/24
We have been working on development of automated preoperative planning system for total hip arthroplasty. Although we have already developed automated planning procedures for implants which are insert...
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...
A Preliminary Study on Early Diagnosis for Dementia Using EEG Topography during Sternberg Task
