多普勒信号
Examples
- Methods two hundred and nine patients who suspected suffering mammoneoplasm were examind , and 218 solid lesions of the shape , boundary , echogenicity , calcification , enhancing or decreasing of post lesion and color doppler signals were observed before operation
方法对209例女性患者( 218个肿瘤)术前进行灰阶超声、彩色多普勒超声检查,观察乳腺肿块形态、边缘、内部回声及钙化、后方回声以及血流信号分布、测定血流参数。 - Results the doppler spectrum of the combined motion of the chamber and the fluid was the vector sum of their doppler signals . conclusion cardiac motion alters the doppler signal derived from blood flow and this effect should be considered in the doppler flow velocity measurement
结论通常所谓的血流速度频谱实际上是血细胞在心脏内流动速度和心脏运动速度的矢量和,即两项运动的复合频谱,所以,为减少误差,在用多普勒血流速度频谱测定血流参数时,应考虑校正问题。 - In this paper , the doppler signed of cartridge velocity , that is produced by the doppler radar , is taken as the research object . the characteristics of the doppler signal of several kinds of cartridges are analyzed . the spectrum analysis method is used to measure the velocity of several kinds of cartridges , based on digital data processing technology and computer graphic technology
