Abstract: Fetal monitoring plays an important role in identifying any possible problem during pregnancy and labor. Electronic fetal monitoring (EFM) is a common form of monitoring which has been widely used at hospitals and clinics. Fetal monitoring can be classified as external or internal monitoring. Fetal heart rate monitoring is a widely adopted approach which checks the rate and pattern of the fetal heartbeat. The detection of abnormal fetal heart rate or pattern is crucial for the medical assessment of fetus well-being and emergence treatment. To achieve high performance monitoring, there are three key issues involved: 1) reliability of an electronic device for data acquisition, 2) accuracy for data analysis and 3) effectiveness of data presentation and sharing. Doppler fetal monitor is an electronic device which uses ultrasound to project the fetus' heart rate for prenatal care. Although Doppler fetal monitors have been well developed with different types of models for various medical and birth settings, most of the existing Doppler models are subject to certain limitations: 1) low reliability caused by the loss of heart beat signals of a fetus; 2) time consuming and lacks of consistency for data analysis conducted by doctors manually; and 3) standalone device without support for interactive data sharing among doctors remotely via internet. Limited remote data transmission and shared interactive reliability of an electronic device for data acquisition, 4) complexity for data analysis and 5) low effectiveness of data presentation and sharing. The work presented in this thesis is concerned with the development of a general framework for effective data presentation and communication over networked fetal monitors. Unlike the traditional Doppler fetal monitors, the contribution of this project includes 1) a new system structure to reduce the loss of signals, 2) new algorithms for computer-aided data analysis for fetal monitoring, 3) use of IP camera network to support online interactive communication between doctors, pregnant women and her partner and family members. The prototype system of networked fetus monitor with remote data printing function demonstrates the feasibilities of the proposed work. The successful implementation of IP camera network facilitates online data sharing to enhance fetal monitoring with new features for effective medical service.
