时间-空间相关成像(spatiotemporal image correlation,STIC)技术从三维影像的电影回放中获得胎儿心脏的数据.与常规二维超声相比,STIC技术能提供更多的观察心脏解剖结构的切面和信息,简化图像采集过程,减少对检查者经验的依赖.STIC技术有多种成像模式,包括重建模式、剖面模式、X线断层超声波成像模式(TUI模式)、容积分析模式(Volume analysis模式),且每一种模式都可以和彩色多普勒、能量多普勒、B-FLOW技术联合应用,医师可根据不同的研究目的选择一种或多种成像模式进行后期脱机分析,从而显示胎儿心脏解剖结构和诊断先天性心脏病.%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 anatony and diagnostic of congenital heart disease
