RAD 330 Image Production and Evaluation II

 

Course Description

A study of the basic principles of radiographic imaging and the production of quality radiographs. The control and understanding of x-ray production, the factors of contrast and density, along with the proper film characteristics and processing of radiographs are developed. Emphasis is placed on experiments designed to give the student practical experience.

 

Introduction

One of the primary responsibilities of the radiologic technologist is to produce high quality medical images. This responsibility is second only to the tenet of excellence in patient care. What constitutes a high quality radiographic image? What are the specific criteria used by the imaging professional to evaluate image quality in an effort to maximize diagnostic success? Most importantly, how does the competent radiographer manipulate a myriad of technical factors to achieve consistently excellent imaging results? A clear and thorough understanding of the principles and operation of imaging equipment is central to the ability to answer these questions. However, your ultimate success in the art of medical imaging requires more than just a mere foundation in the physical attributes of this technology. Attaining true professional competence requires a scientific comprehension that ventures beyond the basic capacity to operate equipment. Our discussions and activities in this course will strive to place you well on the path towards achieving this expertise. With a deep understanding of the technology that surrounds you in the workplace, you will be better equipped to assume a professional competence that elevates your practice of medical imaging to a true art. With this knowledge comes a pride in your work that can greatly enrich your career. Of equal importance is the enormous positive impact it can have on the level of service you provide to your patients and colleagues.

 

Aims

This course has three specific aims:

• to introduce you to the primary principles of radiographic image production;

• to provide you with an extensive analysis of the technical factors of radiographic imaging that allows you to integrate the concept of image quality into your daily professional practice;

• to assist you in developing conceptual expertise in the science of medical imaging, with the ultimate goal of enriching your professional competence and practice in our field.

 

Objectives

Upon completion of this course you should be able to:

• Itemize the components of an x-ray tube and describe the role each plays during radiographic image production.

• Summarize the methods used to control the x-ray beam and describe the effects such control has on the production of the radiographic image.

• Illustrate the design and function of a grid device.

• Appropriately employ a grid in the clinical setting to improve radiographic image quality.

• Describe the construction and function of an intensifying screen.

• Identify the components of radiographic film and describe their role during latent image formation.

• Interpret a sensitometric curve.

• Define radiographic density and describe the controlling and influencing factors.

• Apply the inverse square law and 15% rule to achieve appropriate image density during clinical radiography.

• Define radiographic density and describe the controlling and influencing factors.

• Characterize radiographic images as low or high contrast.

• Define radiographic image resolution and describe the factors that affect it.

• Diagnose the causes of radiographic image distortion and implement appropriate corrective actions.

 

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 classroom 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 may 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.

Student Responsibilities

1. Your participation is expected in all course activities. 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. I will not test you on minor details for the sole purpose of determining whether you’ve done the required readings. The textbook is a valuable resource and I am confident that you’ll find it helpful in your overall understanding of the course content, should you choose to read it.

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 textbooks to class. We will use them 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. All assignments must be completed as scheduled. Late assignments will undergo a 5 % reduction in possible score for each day beyond the due date.

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

9. Failure to notify me prior to a missed exam will result in a zero for that exam.

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!
