Simulation study for the design of an EIT system for cardiac output monitoring

摘要

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.
