Course Policies: 

COURSE  REQUIREMENTS: ATTENDANCE: Attendance is an essential component of the course. Lack of attendance and tardiness may affect your grade.  If you are absent, you are still responsible for the material covered.  As outlined in the El Camino College catalog if, during a semester your hours absent exceed the number of units for the course, (3) you can expect a deficient grade. The student is responsible for all add, drops and withdraws  actions.Attendance is taken at the beginning and end of class. You are also expected to practice courtesy and respect at all times. No children can be brought to class and they cannot sit outside of the classroom. Behaviors that disrupt the learning process will not be tolerated.  These include:
  • Talking to others during lectures, demonstrations, quizzes or exams
  • Sleeping or laying head down during class
  • Checking cell phone messages, text messaging, or answering phone calls
  • Wearing headphones and listening to music
  • Swearing and rude or disrespectful behavior
  • Distasteful or offensive humor
  • Interrupting class, colleagues, or instructor

PARTICIPATION: Participation is an essential component of the course. You are expected to come to class fully prepared and able to participate. Tardiness is an unacceptable habit. Tardiness is not only disruptive and disrespectful, but a sign of poor preparation and interest. Sharing, cooperation, and working with others are a vital component of active learning.  If you arrive late for a quiz, your quiz will still be collected at the same time as the other students. 

DROP POLICY:  It is the student’s responsibility to formally withdraw from the class if they are no longer in attendance. If a formal withdrawal is not completed the student will receive a letter grade of “F” for the course. Do not assume that I have dropped you from the course if you are no longer attending; it is your responsibility to drop the course.

ASSESSMENT:  This course will require a total score of 75% or better on the six exams, quizzes, the cumulative final exam.   You will not pass the class if you do not pass the tests.  


100%-91% 90%-82% 81%-75% 74%-64% 63% and Below
  The student’s final semester grade will be based upon total points scored on quizzes, homework, papers, class work, attendance, participation and examinations.  
ACADEMIC HONESTY: PLAGIARISM, CHEATING, OR FURNISHING MATERIALS IN ORDER TO ENABLE OTHER STUDENTS TO DO SO WILL NOT BE TOLERATED.  Such behavior violates Section I.B.1 of El Camino College’s Board Policy 5138, Standards of Student Conduct.  Anyone cheating will receive zero points for that test, exam, or assignment. Cheating of any kind is a serious breach of personal morality and an offense against your fellow students, your instructors, and the college. No Photos can be taken without permission from the instructor. You may not leave the room during the examination.
STUDENT SUCCESS: As your instructor, my primary goal is your success. If you feel you may require special accommodations please meet with me by week three of the semester.
 FOOD/BEVERAGES: are not permitted in the classroom or lab.  The only exception is bottled water with a cap. 
 Successful completion of this course does not guarantee placement in the next class of the Radiologic Technology Training Program at El Camino College. However, SUCCESSFUL COMPLETION IS REQUIRED for consideration as an applicant for this program. 
*The course schedule is subject to change with prior notice from the instructor

Material will be presented in a power point lecture format.  Power points presentations will be posted on this website weekly.   Students should review the presentation prior to the class meeting.  Students will also be required to participate in various class activities that will require oral presentations and group discussions. There will also be a term paper due near the end of the semester.      

Student Learning Outcome:

  • Students will analyze different methods to reduce radiation dose to the patient in the radiology department.


  • Students will explain the concepts of contrast and density of a radiograph.

  • Students will differentiate between the 5 photon interactions in matter by describing the origin of the interaction and its effect on the body.

Course Objectives:     

  1. Describe the basic differences between diagnostic imaging educational programs and career pathways for Radiologic Technologists and describe the types of imaging modalities used in radiology.
  2. Identify and label the types of equipment used in radiography such as the x-ray tube components, circuitry, image receptors, digital imaging components, film processors and darkroom equipment.
  3. Explain the discovery of x-rays, fundamental properties, and the relationship between x-ray production and photon interaction with matter.
  4. Classify the units of radiation and measurement, and discuss the safety precautions used for technologists and patients
  5. Analyze the relationship of radiographic exposure and as low as reasonably achievable (ALARA) to the direct and indirect biologic effects on humans.
  6. List the exposure factors that are controlled by a technologist and evaluate how these factors can affect radiographic quality, density and contrast on a radiographic image.
  7. Define image detail and distortion, contrast and density, kVp and mAs, and explain their effects on image quality.
  8. Calculate the difference in radiation dose rate using the inverse square law, kilovoltage 15% rule change and the millamperage-seconds doubling rule changes.
  9. Compare and contrast how radiographic images are acquired, processed and viewed with film/screen and digital radiography systems.
  10. Describe picture archiving and communication systems (PACS), digital imaging and communication in medicine (DICOM) and teleradiography and their function in digital imaging and distinguish between the fundamentals of direct and indirect capture.
  11. Discuss the proper locations and methods of obtaining vital signs, medication administration, applying universal precautions for infection control and using effective communication techniques with various types of patients.
  12. Evaluate legal and ethical dilemmas related to the Radiologic Technology profession.
