Z-TRANSFORM METHOD FOR DECONVOLUTION AS APPLIED TO THE RENOGRAM

A method of deconvolution analysis involving the use of the z-transfor m has been developed. When compared to the matrix method, it is shown, under certain circumstances, to be identical. In order to study the v alidity of the method, simple mathematical models have been constructe d. The curves obtained with the computed method closely fitted those o btained by mathematical analysis. The z-transform algorithm was applie d to clinical data in order to demonstrate its validity for the deconv olution of renograms. The advantages of the method over the matrix met hod are discussed.
