Multimedia System Design Illustrating the Operation of Doppler Ultrasound Fetal Monitor in Extracting Cardiac Information

Doppler Ultrasound signal has been used widely in fetal monitor to detect the fetal health status and fetal well-being. A correct understanding of the operation of the monitor and the principles of Doppler ultrasound is essential to medical educator, medical students and clinician in examining the condition of the fetus. Currently, a system that can demonstrate the operation of fetal monitor starting from the Doppler Principles up to the processing of Doppler Ultrasound signals to determine the heart rate is not available. Therefore, this study developed an animation of the operation of the fetal monitor in capturing the ultrasound signal from fetal heart and processing the signal to extract the cardiac information. The multimedia system was designed and developed using Instructional System Design method and Director 8.5 software tool. The multimedia design were divided into five phases; analysis, design, development, implementation and evaluation. The multimedia interfaces contain animated and interactive features which make the learning interesting, enjoyable and highly educational.
