RAD 355 Radiation Physics and Imaging Equipment


Course Description

A review of selected topics in physics as relates to the needs of diagnostic imaging. Topics include electricity, generators, transformers, electrostatics, electrodynamics, and electromagnetism. A comprehensive knowledge of rectification, X-ray circuitry, X-ray tubes, and comparison of various equipment designs.



At the heart of radiographic imaging lies the fundamental conversion of electrical energy into electromagnetic radiation, namely x-ray. To gain a thorough understanding of the physics of radiographic imaging, the technologist must be familiar with the basic concepts of electrodynamics. The study of “electricity in motion” is central to an appreciation of the magnitude and scope of energy used to produce a radiographic image. Modern radiography equipment utilizes extraordinarily complex electric and electromagnetic devices to produce and control x-radiation. The precise operation of these devices is beyond the scope of practice for the diagnostic radiographer. However, a basic understanding of these devices and the basic electrical circuits they operate upon is fundamental knowledge for the fully-competent technologist.



Upon completion of this course you should be able to:

1. Describe the elementary law of electrostatics.

2. Define potential difference, current and resistance.

3. Label basic diagrams of series and parallel x-ray circuits.

4. Calculate amperage, voltage, and resistance in series and parallel circuits.

5. Describe magnetism and electromagnetic induction.

6. Identify the function of solid-state rectification.

7. Compare generators in terms of radiation produced and efficiency.

8. Discuss the proper test equipment/procedures for evaluating the operation of an x-ray generator.

9. Interpret tube rating charts and anode cooling curves to determine safe radiographic exposures.


Course Format

There will be several forms of instruction utilized throughout the semester. Your success in this course is directly correlated to your effort and participation in each:

• The required text book for this course is: Carlton RR, Adler AM. Principles of Radiographic Imaging. 4th ed. Albany: Delmar; 2005 The attached course schedule indicates the section(s) of the text you are required to read prior to each class meeting.

• Our class room discussions will expand upon the material presented within the text readings. Lectures will be supported by various hand-outs, audiovisual materials, and computer presentations.

• I will provide you with additional supplemental readings throughout the semester to assist in your comprehension of the course content.

• Blackboard – all course-related material is available at http://blackboard.hartford.edu. Assignments, supplemental readings and exercises may be periodically administered through Blackboard.

• In addition, the discussion board for this course is a valuable resource for further topic exploration and clarification. You may find it helpful to discuss amongst yourselves the topics we cover throughout the course. I will routinely monitor the discussion board and will provide additional instruction when necessary.

• Please familiarize yourself with Blackboard and speak to me if you have any issue with access or utilization.



Your progress and overall course achievement will be calculated in the following manner:

Measure % of Grade
Worksheets 60
Lab exercises 15
Final Exam 20
Participation 5

*A grade of C+ (77%) or above in this course is required to continue within the Radiologic Technology professional component curriculum. (Policies and Procedures, pg. 5)


Student Responsibilities

1. Your attendance is expected at all class meetings. Please contact me prior to class via phone or e-mail if you are unable to attend a lecture session. It is your responsibility to obtain the covered course content for any missed lectures.

2. Read the assigned materials prior to each lecture. You should take notes during class, the ease of which will be facilitated by at least a cursory understanding of the material.

3. You are responsible for all of the material contained within the assigned readings and activities. Your understanding of all major concepts will be assessed through our various assignments and tests. Be aware that I will not test you on minutiae; the assessment tools I use to measure your progress will concentrate primarily on the major topics we explore during our meetings and homework assignments.

4. Pay attention and participate in our lecture discussions. Appropriately asked questions are always welcome – never hesitate to raise your hand and ask for further clarification when needed.

5. Bring your textbook to class. We will use it often during both independent and collaborative exercises.

6. The use of cell-phones, pagers, or other electronic communication devices during class is strictly prohibited.

7. Please keep in-class food/drink to a minimum. This course consists of ten 3 hour sessions. Each will have a 15 minute break mid-way, at a minimum. Please try to refrain from eating until the session break.

8. All assignments must be completed as scheduled. Late assignments will undergo a 5 point reduction in possible score for each day beyond the due date.

9. All exams must be taken as scheduled. Make-up exams will be given only in extreme circumstances and must have my prior approval.

10. Students in need of learning accommodations may discuss this directly with me and/or contact the University’s Learning Plus office at 860-768-4522.

11. Students of the course are subject to the rules and regulations of the University of Hartford’s Academic Honesty Policy and Code of Student Conduct as outlined in The Source.

12. Students may appeal any component of this course in accordance with the Academic Grievance Procedure as outlined in the Policies and Procedures Manual of the Radiologic Technology Program.


I look forward to a productive and rewarding semester. It is my honor and pleasure to assist you in your professional studies in the science and practice of Radiologic Technology. Best wishes for success!
