I don't (yet) know enough about IRIS Performer to give a "direct answer",
but...

Have you read Robert Fraser's whitepaper on Volume Rendering? It
describes how the technique works using IRIS GL/Open GL functionality
(which might give you ideas as to how an IRIS Performer app could be
implemented). The section on "Advanced Rendering Techniques" describes
how MRI and CT data can be merged.
