Optimum Modeling of Vascular Beds Using Indicator-Dilution Measurements

This paper considers the model of a vascular bed as H(s) with possibly an infinite number of poles. It then solves the problem of identifying a suitable low order approximation to it. The optimal model order and parameter estimates are found based on the critereon similar to that developed by Akaike [5]. This method prevents a direct deconvolution. Deconvolution is known to be sensitive to errors.
