Biomedical Signal Analysis for Automatic Detection of Diseases and Disorders in Prenatal Age

While examining biomedical signals, signal classification as well as measurements, quantifications and their assessment is very important for studying different diseases and disorders. Through this paper, we have focused on different signals and biomedical devices, whose purpose is to give high quality information about diseases and disorders in prenatal age. The main focus was on ultrasound techniques and the relationship between 2D, 3D and 4D ultrasound, on Doppler ultrasound, cardiotocography, KANET test, and in general, comparison of standardized and automated techniques. Purpose of this paper is to compare some of the available techniques used to assess the fetus in the womb, how they advance through time and whether they are being automated.
