Any software devoted to medical devices or in vitro diagnostic has to be conformed with the ISO 62304. The risks and performances associated with the software outcomes has to be fully controlled. Unfortunately the number of internal parameters to be tuned can drop drastically and at the same time the number of trials and therefore the time of development.
We present thereafter how the Quality-by-Design approach has been applied to the optimal tuning of a software devoted to the detection of a pathology. Two requirements of sensitivity and specificity are specified. At the end, two tuning parameters have been investigated to find the region in which the targeted objectives can be reached.
This type of study allows to quickly find the parameter settings leading to the optimal performances.
