Abstract :
This simulation study explores system design requirements needed for an EIT system that will be capable of accurately monitoring cadiac output. The 4D XCAT model is used to construct a realastic time-depedent conductivity profile of the chest. Forward and inverse simulations are calculated using Dartmouth´s NDRM EIT software package. Error analysis revealed that an SNR of 85-91 dB is preferred to confidently measure cardiac output.
