Some of the newer RT systems like Tomotherapy and Trilogy take a daily CT scan. In addition to helping get precise alignments it lets the RO see daily changes.

Apparently these lower power daily scans don't have the definition of full power CT scans, but the ones the RO went over with me seemed fairly well defined (kind of like mini PET scans of my head and neck).
