Abstract :
According to preliminary information on the physiological system, two extreme cases of identification may be distinguished. If the structure is known it is a case of parameter assessment. If the structure of the mathematical model is unknown it is a case of a real identification problem. In our case the diagnostic tests define the model structure, hence evaluation of measurement results simplifies to parameter assessment. This paper focuses on the parameter assessment of the evaluation of liver flow tests by colloid 198 Au and a new event recognition method
