Signals of the heart (electrocardiogram, EKG), and neural signals (electroencephalogram, EEG) in the fetus can not be detected directly when the fetus is still in the womb. Through this study, ECG signals and fetal EEG signals have been obtained through ultrasonographic imaging (Ultrasound) imaging using synthetic models and recording imaging models with computational approaches. In this study fetal ultrasound samples were taken from 5 fetuses in the womb over the age of 16 weeks. The results of fetal ultrasound recordings were converted into jpg format, then processed using the program Modeling of Fetal ECG and Imaging Using Ultrasound software based on Wolfram Matematica 9. In this image processing, the frequency used in the modeling program were 0.5 MHz, 1.5 MHz, 2.5 MHz, 3.5 MHz, 5.0 MHz and 10 MHz. Fetal ECG signals were successfully performed on five fetal samples with variant frequency. ECG signal form of the five fetal samples produce the same ECG signal pattern using the same frequencies of 0.5 MHz, 1.5 MHz, 2.5 MHz, 3 MHz, 5 MHz and 10 MHz. According to European standards, the shape of fetal ECG signals on each segment of the signal pattern has a normal fetal ECG range segment. EEG signal pattern generated in the five samples produce the same EEG signal pattern at each of the same frequency values. The greater frequency used it will produce the initial movement of waves.The situation was magnitude of the amplitude generated at the frequency of 5 MHz and 10 MHz which were -3 (a.u) and 4 (a.u). EEG signal amplitude at the beginning was 3.5 (a.u) then drop gradually to 3.0 (a.u) during very short time (0 sampai 1.0 μs). The frequency affect the trun of recording image generated on programs with a frequency of 0.5 MHz resulting in a black color image focus, a frequency of 1.5 MHz and a 2.5 MHz resulting in the sharpest focus of the image. Would remove the tape or the tape just to show white.
Key words: Ultrasound, EKG, EEG, Focus Image Record, Modeling Program.
