Fetal ECG extraction has an important role in the medical diagnosis during pregnancy. This problem can be modeled from the approach of blind source extraction. The mathematical modeling of fetal ECG extraction using ICA algorithm is described in this paper. It also proposes an efficient BSS method (FCOMBI) for the extraction of fetal ECG. This algorithm combines the strengths of non-Gaussianity...

The brain – computer interface (BCI) provides a communicational channel between human and machine. Most of these systems are based on brain activities. Brain Computer-Interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. The success of this methodology depends on the selection of methods to process the brain signals in each pha...

campylobacteriosis is an important infectious disease of animals and humans caused by the pathogenic campylobacter species. a total number of 132 aborted sheep fetuses and related placentas were admitted to the large animal clinic at the university of tabriz, from october 2010 to march 2011. tissue samples were collected from several fetal organs including liver, brain, kidney, lung, spleen, he...

Brain segmentation is a fundamental first step in neuroimage analysis. In the case of fetal MRI, it is particularly challenging and important due to the arbitrary orientation of the fetus, organs that surround the fetal head, and intermittent fetal motion. Several promising methods have been proposed but are limited in their performance in challenging cases and in realtime segmentation. We aime...

objective: fetal development of the central nervous system is an important and sensitive stage which is affected by many external and internal stimuli. this study aimed to investigate effect of musical stimuli on fetal rat brain. materials and methods: in this experimental study, twelve female wistar rats were selected and evenly assigned to control and musical groups. the females were mated wi...

The prenatal period is a critical time for neurodevelopment and is thus a period of vulnerability during which a range of exposures have been found to exert long-term changes on brain development and behavior with implications for physical and psychiatric health. During fetal life, neurons proliferate, migrate and form connections, providing the structure of the developing brain. Neurons reach ...

objective(s): nowadays much effort is being invested in order to diagnose the mechanisms involved in neural differentiation. by clarifying this, making desired neural cells in vitro and applying them into diverse neurological disorders suffered from neural cell malfunctions could be a feasible choice. thus, the present study assessed the capability of fetal brain extract (fbe) to induce rat bon...

Background: Extraction of Fetal ECG signal from non-invasive abdominal ECG signal is an important clinical application. Fetal ECG signal provides significant and valuable information about the fetal heart growth and health condition. Objective: Abdominal signals are usually corrupted by high amplitude maternal ECG signals and often found superimposed with the Fetal ECG signal. Suppression of ma...

Electrocardiogram (ECG) is a valuable technique that has been in use for over a century. The analysis of fetal ECG signal has always been an interesting topic in the field of signal processing. The presence of noises in the ECG signal causes distortion in the signal morphology. While analyzing the fetal ECG this distortion of the signal is much more severe as the fetal ECG is much weaker than t...
