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...
Dynamic Analysis of Cardiac Excitation Propagation in Optical Mapping
optical mapping conduction velocity vector field spiral wave reentry isochronal map
2009/6/9
A method to estimate the speed and direction of wave propagation of cardiac excitation in optical mapping and the utility are presented in this paper. Optical mapping has been widely used in arrhythmi...

Interaction between resting pulmonary ventilation function and cardiac autonomic function assessed by heart rate variability in young adults
resting pulmonary ventilation function cardiac autonomic function heart rate variability young adults
2009/3/2
An association between ambient air pollution and reduced cardiac autonomic function assessed by heart rate variability (HRV) mainly in elderly persons has been suggested by a number of epidemiologic...
Identifying diabetic patients with cardiac autonomic neuropathy by heart rate complexity analysis
diabetic patients cardiac autonomic neuropathy heart rate
2010/2/25
Cardiac autonomic neuropathy (CAN) in diabetes has been called a "silent killer", because so few patients realize that they suffer from it, and yet its effect can be lethal. Early sub clinical detecti...
A model-based time-reversal of left ventricular motion improves cardiac motion analysis using tagged MRI data
left ventricular motion cardiac motion analysis tagged MRI data
2010/2/25
To improve the estimation performance of large cardiac motions while analyzing tMRI data sets, we propose a two-step solution. The first step involves constructing a model to describe average systolic...
Utilizing FEM-Software to quantify pre- and post-interventional cardiac reconstruction data based on modelling data sets from surgical ventricular repair therapy (SVRT) and cardiac resynchronisation therapy (CRT)
FEM-Software cardiac reconstruction data surgical ventricular repair therapy cardiac resynchronisation therapy
2010/2/26
The operation results for both patients are quantified. The quantification shows treatment details for both interventions (e.g. the elimination of the discontinuities for CRT intervention and the segm...
Analysis of cardiac signals using spatial filling index and time-frequency domain
cardiac signals spatial filling index time-frequency domain
2010/3/1
This paper presents the spatial filling index and time-frequency analysis of heart rate variability signal for disease identification. Renyi's entropy is evaluated for the signal in the Wigner-Ville a...
Cardiac arrhythmia classification using autoregressive modeling
Cardiac arrhythmia classification autoregressive modeling
2010/3/1
AR modeling results showed that an order of four was sufficient for modeling the ECG signals. The accuracy of detecting NSR, APC, PVC, SVT, VT and VF were 93.2% to 100% using the GLM based classificat...
