Abstract
Five different methods for filtering the renogram are comparec: (a) conventional smoothing, (b) data bounding, (c) polynomial fitting, (d) smoothing by spline functions and (e) manual graphical fitting. The purpose of the study was to assess how well the techniques retained 'true' features of the curve while removing the statistical and physiological noise.This publication has 6 references indexed in Scilit:
