The Effect of Experience Extension on The Activity of Calculating Fetal Movement Third Trimester of Primiparaous

Based on research by the World Health Organization (WHO), around the world there are 10,000,000 infant deaths per year in Indonesia, among ASEAN countries, is the country with the highest perinatal mortality rate, meaning that the ability to provide health services still requires improvements that are comprehensive and of higher quality. Integrated ANC services are also related to effective counseling activities in an effort to improve maternal knowledge about pregnancy care, especially the activity of calculating gesture). The purpose of this study is to determine the effect of experimental counseling fetal motion in third-trimester primigravida. The design in this study was pregnant post nonequivalent control group test. The study was conducted in Meninting Community Health Center, West Lombok Regency. The population of this study was the third trimester of pregnant women, namely 80 people. The sample of this study was 34 people. Test statistics using the Mann Whitney test and Fisher's Exact Test with confidence levels specified α = 0.05 and 95% confidence intervals. The results of the study with the Mann Whitney test P = 0,000 means that there is a significant difference between knowledge about calculating fetal motion in the case group compared to the control group and the Fisher's Exact Test P = 0,000 shows there is an influence of experimental counseling on the activity of calculating fetal movement. The recommendations of this study are to examine the effectiveness of calculating fetal motion for fetal distress.

Inter-slice motion correction using spatiotemporal interpolation for functional magnetic resonance imaging of the moving fetus

Fetal motion continues to be one of the major artifacts in in-utero functional MRI; interestingly few methods have been developed to address fetal motion correction. In this study, we propose a robust method for motion correction in fetal fMRI by which both inter-slice and inter-volume motion artifacts are jointly corrected. To accomplish this, an original volume is temporally split into odd and even slices, and then voxel intensities are spatially and temporally interpolated in the process of image registration. Our experimental data demonstrate that our method was more effective in correcting fetal motion artifact compared to traditional motion correction methods.

Histograms of Oriented 3D Gradients for Fully Automated Fetal Brain Localization and Robust Motion Correction in 3 T Magnetic Resonance Images

Fetal brain magnetic resonance imaging (MRI) is a rapidly emerging diagnostic imaging tool. However, automated fetal brain localization is one of the biggest obstacles in expediting and fully automating large-scale fetal MRI processing. We propose a method for automatic localization of fetal brain in 3 T MRI when the images are acquired as a stack of 2D slices that are misaligned due to fetal motion. First, the Histogram of Oriented Gradients (HOG) feature descriptor is extended from 2D to 3D images. Then, a sliding window is used to assign a score to all possible windows in an image, depending on the likelihood of it containing a brain, and the window with the highest score is selected. In our evaluation experiments using a leave-one-out cross-validation strategy, we achieved 96% of complete brain localization using a database of 104 MRI scans at gestational ages between 34 and 38 weeks. We carried out comparisons against template matching and random forest based regression methods and the proposed method showed superior performance. We also showed the application of the proposed method in the optimization of fetal motion correction and how it is essential for the reconstruction process. The method is robust and does not rely on any prior knowledge of fetal brain development.
