中空纤维透析器是一种用于血液透析治疗严重肾脏问题的设备。在这种装置的设计中，血液流速和透析器内部的超滤速度的测量是非常重要的。本文提出了一种新的非侵入式测量方法来处理这项工作。该方法采用CT（Computed Tomography）系统采集密集集束中空纤维透析器内部的血液运动数据，然后采用一系列图像处理方法，测量血液流速和超滤速度。(C)2010爱思唯尔有限公司版权所有。
Hollow fiber dialyzer is a device used for years in the therapy of hemodialysis treating people with severe kidney problems. in the design of such a device, the measurement of the blood flow velocity and the ultra-filtration velocity inside the dialyzer are very important. And non-Invasive measurement solutions are highly desired during experiment This paper presents a novel non-invasive measurement method to handle this work. The method adopts a CT (Computed Tomography) system to acquire blood motion data inside a densely bundled hollow fiber dialyzer, and then, by adopting a series of image processing methods, the blood flow velocity as well as the ultra-filtration velocity is measured.
