Abstract
Abstract
In medical and laboratory procedures used to obtain useful information to diagnose a disease it is very important not to cause harm to the patient. In the detection of heart disease in fetuses in the mother’s womb, a safe and non-invasive procedure is fetal phonocardiography. In this procedure, an electronic stethoscope captures the sound emitted by the baby’s heart, transforms it into an image and is displayed on a computer screen and a subsequent analysis of that image is performed. This paper shows the procedure to obtain the phonocardiogram of an unborn baby and an algorithm for extracting from it the sounds from the mother’s heart and other physiological noises. The purpose is to recognize if in the acoustic image there are anomalies that allow us to identify congenital or other type lesions in the heart of the fetus.
