高精度数据采集在EIT系统中的应用
High Precision Data Collection in EIT
根据乳腺的EIT检测方法的特点，设计了一套16电极的包括电极、开关阵列、模拟前端、模数转换及数据传送等一体化的面向乳腺EIT检测的高精度实验系统。采用了真正意义上的完整的数据采集系统芯片ADuC834，使用了环形电路板，将所有电路集中在该电路板上，以16个压力测试针作为与外部电极的接合点，实现了无长引线的一体化系统。使用该系统进行了初步成像实验，取得了较好的成像结果。
We have designed a high precision integrate system for breast electrical impedance tomography, which include electrodes, switch array, analog preamplifier, A/D conversion and data transmission system, based on the properties of the detective method for breast using electrical impedance tomography. This integrate system, which has no long lines, takes 16 pressure detective needles as the connective points to the outer electrode, using the real full data collect chip, ADuC834, and a circular board, integrated all circuits on it. Using this system, preliminary experience has been made, some reconstructed images has been obtained.
