为了探讨、研究儿童期头部血流动力学的变化,建立适合于评价我国儿童脑循环血流动力学的定量标准。本文测定了儿童头部各血管血流速度,将该组资料报道如下。1 资料与方法1.1 选择对象:健康儿童男30例,女30例。1.2 检测仪器:三维经颅多普勒超声扫描仪(3D-TCD)。探头频率2MHz,能量输出32％～
In order to explore, to study changes of head hemodynamics in childhood, to establish a quantitative standard suitable for evaluating cerebral circulation hemodynamics in children in our country. This paper measured the blood flow in the head of children’s blood flow, the group reported the following data. 1 Materials and Methods 1.1 Select the object: healthy children 30 men and 30 women. 1.2 detection equipment: three-dimensional transcranial Doppler ultrasound scanner (3D-TCD). Probe frequency 2MHz, energy output 32% ~
