Course Description: RADS 1312 (RADR 1213). PRINCIPLES OF RADIOGRAPHIC IMAGING I. This course will analyze radiographic image qualities and the effects of exposure variables upon these qualities. Prerequisite: Admission to the Program.
The student will define, recognize, and evaluate qualities of the radiographic image, and analyze the effects of exposure variables upon each image quality.
This course is a study of radiographic principles relating to radiographic quality. Included is an introduction to film and patient identification issues, legal ramifications of the use of film and patient identification markers, density, contrast, and various other quality factors such as detail, distortion, motion, artifacts, double exposure, grids, and positioning.
The Secretary’s Commission on Achieving Necessary Skills (SCANS) was established to determine skills that students need in order to succeed in the work environment.
Description of Scans competencies as follows:
Upon completion of this course the student will be able to:
Recognize proper patient identification on the radiograph
Identify appropriate positioning marker location
Evaluate radiographs for appropriate film size and axis
Determine acceptable identification blocker placement
Discuss the legal ramifications of improper use of film and patient identification
Differentiate between the concepts of vision and perception
Discuss the effects filtration has on the patient and the finished radiograph
Identify the prime factors in radiographic exposure
Discuss patient and technologist safety relating to the patient as a beam emitter.
Utilize a grid and give examples of grid benefits and errors.
Categorize the components of radiographic screens according to function.
Combine different films with varying speed and screen types for the purpose of comparison.
Perform sensitometry on radiographs to determine what exposure latitude, contrast, and speed exists on a particular film.
Recognize both patient and equipment generated artifacts on radiographs.
It is imperative that you complete the readings and be familiar with the course notes before you come to class. This course is very interactive which means that you will be required to participate in class discussions and respond thoughtfully to questions during the discussions and ask questions when you need answers. You are also expected to be active in the laboratory sessions and push yourself to really understand the material.
It is strongly suggested that you purchase inexpensive scrub uniforms to wear during lab sessions. Regardless of whether you purchase scrubs, you must wear shirts and drawstring pants with no buttons or zippers to avoid damaging examination tables. You may be dismissed from class and penalized with an absence if you do not comply to this dress code.
As emerging professionals it is your responsibility to demonstrate professional behavior by attending each and every learning opportunity. If an emergency occurs, your must inform the instructor at least 15 minutes prior to the start of class if you are going to be either late or absent. For each time you are late, 1 point will be deducted from your final grade. For each time you are absent, 2 points will be deducted from your final grade. Three absences will result in dismissal from this course. Additionally, the inability to be prompt is considered unprofessional and irresponsible behavior. Three instances of being late will result in a letter grade reduction
Honesty is a necessary trait in all health care professionals. It is assumed by the instructor that all students practice honest and ethical behavior in the classroom. Inability to fulfill this assumption will result in the student receiving a failing grade in the course. The University and Department policy regarding dishonesty will be strictly enforced. You are not only expected to be honest in your own actions, but to report dishonest activities as well. Please refer to the University and Department handbooks for more detailed information.
Methodology / Teaching Strategies:
Lecture/discussion, group activities including laboratory, independent reading assignments, group discussion, written assignments, and student presentations.
Students must participate in classroom activities to gain full benefit from the course. This does not mean that students can be disruptive and interfere with the learning process for their peers. Students should practice professional behavior in the classroom equal to what is expected in the work force. Failure to fulfill this expectation will result in the student being expelled from the classroom. I prefer that cell phones never enter the classroom; however, if you must have it with you, then it must be off. If your cell phone goes off during class, you will be asked to leave and you will receive a reduction in attendance points.
