    • The invention refers to a method for carrying out data collection on electrodes placed on a body for subsequent processing of an electrical impedance tomography image of a corresponding part of said body. In order to improve the resolution of electrical impedance tomography systems without noticeably affecting the signal-to-noise ratio, the method according to the invention comprises the steps of placing the electrodes on a peripheral line around the body, applying a current pattern from a current source to at least one pair of electrodes, and measuring differential potentials between pairs of electrodes, wherein at least one intermediate electrode lies in between each pair of electrodes for measuring the differential potentials and the differential potentials of one current pattern for the subsequent image processing refer to at least three different pairs of electrodes with no electrode used more than twice for each current pattern.
    • 本发明涉及一种用于在放置在身体上的电极上进行数据收集的方法,用于随后处理所述身体的相应部分的电阻断层图像。 为了提高电阻抗层析成像系统的分辨率而不显着影响信噪比,根据本发明的方法包括以下步骤:将电极放置在围绕身体的外围线上,从电流施加电流模式 源极到至少一对电极,并且测量电极对之间的微分电位,其中至少一个中间电极位于每对电极之间,用于测量差分电位,并且用于后续图像处理的一个电流图案的微分电位参考 至少三个不同对的电极,每个电流图案没有电极使用两次以上。
