[Quality assurance of the renal applications software].
BACKGROUND
The need for quality assurance of all technical aspects of nuclear medicine studies is widely recognised. However, little attention has been paid to the quality assurance of the applications software. Our work reported here aims at verifying the analysis software for processing of renal nuclear medicine studies (renograms).


METHODS
The software tools were used to build a synthetic dynamic model of renal system. The model consists of two phases: perfusion and function. The organs of interest (kidneys, bladder and aortic artery) were simple geometric forms. The uptake of the renal structures was described by mathematic functions. Curves corresponding to normal or pathological conditions were simulated for kidneys, bladder and aortic artery by appropriate selection of parameters.


RESULTS
There was no difference between the parameters of the mathematic curves and the quantitative data produced by the renal analysis program.


CONCLUSIONS
Our test procedure is simple to apply, reliable, reproducible and rapid to verify the renal applications software.
