Course Objectives

This Internet-based course explores the basic physical and technical principles of CT scanning.  Computer technology, system components, image characteristics, and quality control methods are introduced.  This course is designed to aid the student in preparation for the A.R.R.T.’s CT registry.  The student MUST have access to a CT unit to complete the laboratory portion of this course.

Course Expectations

This course is divided into individual study units. A list of learning objectives is found at the beginning of each study unit. You should read each objective so that you'll know what you're expected to learn from that particular unit of instruction. The examinations for this course are based on those learning objectives.

After you finish a unit of instruction you should complete the review exercises found at the end of the unit. You may search through the text to find any answer. The review exercises are designed to help prepare you for the unit examinations. 

Unit Exams

A Unit Examination accompanies each unit of instruction. Although each Unit Exam may be an "open book" evaluation of the text, you should first try to answer all questions without referring to the instructional materials. Each Unit Examination answer will be graded in realtime and feedback will be given for each response. You are encouraged to print the given feedback to help you prepare for the Diagnostic and Final Exams.  Recommended due dates are published in the Course Calendar.  No penalty will be assessed for submissions after the recommended due dates.  A 10% penalty will be assessed for exams submitted after the absolute due date published in the Course Calendar.

Plagiarism Policy Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception. Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters. We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student. We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed. Written and adopted by the 2002-2003 MSU Student Senate.

Safe Zones Statement The professor considers this classroom to be a place where you will be treated with respect as a human being - regardless of gender, race, ethnicity, national origin, religious affiliation, sexual orientation, political beliefs, age, or ability. Additionally, diversity of thought is appreciated and encouraged, provided you can agree to disagree. It is the professor's expectation that ALL students consider the classroom a safe environment.
