Catalog Description (Insert new/revised description below):
This course is one of four didactic courses designed for the Radiologic
Technologists Registered (or registry eligible new graduates) in Radiography
through the ARRT. This course is designed for the Technologist who is seeking
one of the following: post primary certification in Computer Tomography (CT)
through the ARRT, employment as a CT technologist, or ARRT category A
continuing education credits. The content is designed to impart an understanding
of the physical principles and instrumentation involved in computed tomography.

Assessment of Student Learning
[Methods of assessment should be appropriate for Learning Outcomes listed
above.]
Students are assessed through written quizzes and exams, written reports,
projects, presentation, and on-line discussions.
Assessment of student learning outcomes for the course, as required by AP 765, is
part of regular curriculum maintenance and/or improvement. The specific plan
has been determined by the pertinent faculty involved and is kept on file in the
division office.
