Registration problems requirefinding the mapping of information acquired in one coordinate system to relatedinformation acquired in a second (possibly the same as the first) coordinatesystem. In many computer-assisted surgical applications, the patient's anatomymust be registered to a pre-operative plan before navigational information canbe conveyed to the surgeon; thus, registration is a single-point of failure insuch applications. It is important that designers and users ofcomputer-assisted surgical systems understand how measurement errors that occurduring the registration process affect the accuracy of the computed registrationtransformation. In the first part of this talk I will describe the registrationproblem and define the basic terminology used to describe registration error incomputer-assisted surgical applications. I will then show how we can constructa model of registration error that we can use to predict its behaviour. In thesecond part of this talk I will discuss how the topic of registration errorcould be incorporated into an undergraduate and/or graduate course.
