摘要
由于成像质量较差,限制了生物电阻抗断层成像技术的临床应用。本文在介绍生物电阻抗断层断层成像研究概况的基础上,指出了影响成像质量的主要问题是成像过程中的病态性问题,并讨论了形成病态性的主要因素是:①驱动测量模式;②重构模型;③图像重构算法。
Clinical application of biological electrical impedance tomography is limited mainly due to its poor image quality.This paper reviews the study of biological electrical impedance tomography,and points out the key problem for image quality which is the ill-posed condition in reconstruction.Based on this,three influencing factors are descuseed:①the driven patten;②the model to reconstruct images;③the reconstruction algorithms.
