Abstract: The spatiotemporal image correlation（STIC） technology acquires the fetal heart data from the movie playback of the three-dimensional images. Compared with conventional two-dimensional ultrasound, STIC technology can provide more cardiac anatomy section observation and information, simplify the image acquisition process, reduce dependence on examiner experience. STIC technology has a variety of imaging modes, including the render mode, sect. planes mode, TUI mode, Volume analysis mode ,and each mode can be combinationed with color Doppler, power Doppler, B-FLOW technology. Physician can select different imaging modes to help offline analysis, which showed fetal heart anatomy and diagnostic of congenital heart disease

Key words: Spatiotemporal image correlation technology, Imaging, three-dimensional, Maging mode, Fetal heart
