A NOVEL APPROACH & A ROBUST TECHNIQUE FOR FETAL ECG ANALYSIS Name of Institution: Sri Ramakrishna Engineering College, Coimbatore Author(s): N.Ashwathy, R.Na garajan, M.Shanmuga nand, E.Siva Shanmuganat han Guided by: Ms.N.Manju. Contest Category (Student/Research Scholar): Student Benefits of using Virtual Instrumentation : Using ELVIS the acquisition of real time data and pre processing of obtained data were made easy. The in-built LabVIEW tools saved a lot of time and also helped in acquiring accurate results. National Instruments products (Hardware and Software) used: Hardware: 1. ELVIS 2. DAQ (Data Acquisition) Software: 3. LabVIEW 8.1(Advanced Signal Processing Toolkit, Digital Filter Design Toolkit) Problem we were trying to solve: We were trying to remove the contaminants from the Maternal Abdominal signal and to extract fetal ECG. Solution to the problem: Using wavelet transform and Adaptive signal processing to remove the contaminants and using Independent Component Analysis to extract various features in the Fetal ECG Introduction to the Application: Monitoring the condition of fetus at several stages of pregnancy by a successful method and a relatively inexpensive equipment which could be adopted for monitoring the fetal ECG at rural health centre and even at home Brief description of the Application: The application is arrived at by obtaining the fetal ECG from the mother’s abdomen using multi-lead cutaneous electrodes. The position of the electrodes and the number of electrodes used determines the nature of the signal obtained. The obtained ECG contains a number of contaminants and a strong interference from maternal electrical activity. The denoising of this signal is done using wavelet transform which removes Power Line Interference, Base Line Wandering and other wide-band noises. The intervention of maternal ECG over the FECG can be removed by using Adaptive Signal Processing (ASP).The required features of the fetal ECG is then extracted using Independent Component Analysis (ICA).
