超声心动图是M型扫描调辉显示,回波信号的周期为微秒级,目前国内皆采用照相的办法记录图象。用照相法时,为了保证图象的完整性,其摄影动作必须严格地与图象扫描同步,即医生在任意时刻发出摄影指令后,应在下一帧扫描开始之际照相机快门(B门)自动打开,该帧扫描结束时照相机快门应立即关闭。此外它还应有较高的抗干扰性能。本文介绍我们采用的一种简便而可靠的自动同步摄影控制技术,二年来它成功地运用于临床,在自动化和保证图象的完整性上效果良好,我以为在目前我国还没有使用光导纤维记录和录象技术
Echocardiography is the M-type scanning tone display, the echo signal cycle of microseconds, the current domestic use of photographic methods to record images. When using photographic method, in order to ensure the integrity of the image, the photographic action must be strictly synchronized with the image scanning, that is, the doctor at any time after the issue of photographic instructions should be the next frame scan when the camera shutter (B door) automatically On, the camera shutter should be closed immediately after the end of the frame scan. In addition it should have higher anti-jamming performance. This article describes a simple and reliable automatic synchro photography control technology that we used. It has been successfully used in clinical practice for two years. It works well in automating and ensuring the integrity of images. I think that at present, China has not used optical fiber recording And video technology
