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) technique obtains fetal heart data from movie playback of three-dimensional images. Compared with conventional two-dimensional ultrasound, STIC technology can provide more observations of heart anatomy and information, simplify the image acquisition process, reduce the experience of the examiner’s dependence. STIC technology has a variety of imaging modalities, including reconstruction mode, profile mode, X-ray tomography (TUI mode), volume analysis mode (Volume analysis mode), and each mode can be combined with color Doppler, Puller, B-FLOW technology combined, the doctor can choose one or more imaging mode for different research purposes for post-off-line analysis to show fetal heart anatomy and diagnosis of congenital heart disease.
