Opportunities and Limitations of Non-invasive Bioelectric Imaging of the Heart
نویسندگان
چکیده
The spatial resolution of Bioelectric Imaging of the Heart was investigated. Based on the measurement of a multichannel Electrocardiogram (ECG) or Magnetocardiogram (MCG) images of epicardial potential distributions can be reconstructed. The imaging properties of this method have been investigated using Computer simulations. The spatial resolution depends strongly on the number and arrangement of electrodes and magnetometers, on the noise level of the sensors and on the individual morphology of the patient. Artefacts show up if errors in the torso model (geometry and/or impedance values) occur.

Non-invasive estimation of cardiac wall stress by using tissue doppler-echocardiography ultrasound images: People with coronary artery stenosis
In this study, a method for non-invasive estimation of stress on the heart wall in the diastole phase is presented using ultrasound echocardiography and tissue Doppler imaging. The aim of this study was to evaluate the stress on the heart wall as a pre-diagnosis to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...

Magnetic resonance imaging (MRI) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. Advantages and disadvantages of MRI are not fully understood; however, it has been commonly used in the diagnosis of skeleton and bone diseases (such as disk and spinal disorders, joint disorders (arthritis), bone tumours and tissues...
متن کاملEvaluation of Cardiac Mitochondrial Function by a Nuclear Imaging Technique using Technetium-99m-MIBI Uptake Kinetics
Mitochondria play an important role in energy production for the cell. The proper function of a myocardial cell largely depends on the functional capacity of the mitochondria. Therefore it is necessary to establish a novel and reliable method for a non-invasive assessment of mitochondrial function and metabolism in humans. Although originally designed for evaluating myocardial perfusion, 99mTc...

Myocardial perfusion SPECT imaging with Tc99m-sestamibi is the most accurate non-invasive means of detecting coronary artery disease and assessing the severity of perfusion abnormalities in the patients with coronary stenosis. Though simple and straight forward the results produced by the technique is very much affected by the details being used. One of the main problems with the test, wh...
