编码超声血流多深度检测（英文）
发布时间：2018-09-07 12:56
【摘要】：血流信息检测及其成像因其独特的优势,在临床上得到广泛应用。但常规经颅多普勒超声系统仍采用模拟和数字电路结合的传统技术,这类系统容易受到外界干扰且不能进行多深度检测。文章设计出一种全数字多普勒超声血流检测系统方案,弥补了传统模拟系统存在的问题。多普勒仿体和人体实验结果表明,该系统能够进行多深度检测,确定血管的深度;同时,还提高了检测灵敏度、超声穿透力和系统成像分辨率。
[Abstract]:Blood flow information detection and imaging are widely used in clinic because of their unique advantages. However, the conventional transcranial Doppler ultrasound system still uses the traditional technology of analog and digital circuits. This kind of system is vulnerable to external interference and can not carry out multi-depth detection. In this paper, a scheme of all-digital Doppler ultrasound blood flow detection system is designed, which makes up for the problems existing in the traditional analog system. The results of doppler simulation and human body experiments show that the system can be used for multi-depth detection to determine the depth of blood vessels, and at the same time, the detection sensitivity, ultrasonic penetration and imaging resolution of the system are improved.
