Z-transform method for deconvolution as applied to the renogram.
A method of deconvolution analysis involving the use of the z-transform has been developed. When compared to the matrix method, it is shown, under certain circumstances, to be identical. In order to study the validity of the method, simple mathematical models have been constructed. The curves obtained with the computed method closely fitted those obtained by mathematical analysis. The z-transform algorithm was applied to clinical data in order to demonstrate its validity for the deconvolution of renograms. The advantages of the method over the matrix method are discussed.
