ABSTRACT
In the preceding chapter, the propagation of key measures through imaging systems was reviewed. In that discussion it was implicitly assumed that the key measures were known for each of the system components. Determining such key measures is not necessarily a straightforward task, and even if the task is well understood, it may be costly in terms of required resources. In this chapter and the next we describe strategies for predicting or experimentally determining key measures in an efficient manner. The present chapter focuses on the use of parametric estimations of key measures, in lieu of experimental measurements.
