Zhang J, Patterson R
Conf Proc IEEE Eng Med Biol Soc
. 2007 Feb;
2004:1557-60.
PMID: 17271995
Monitoring lung air and fluid volume is a promising EIT application. Respiratory activity causes both chest expansion and position changes of tissues/organs in the thorax, which contributes measurement error. In...
