Intent of Project

The intent of this mini-course is to address the need for additional education for technologists that entered the field of radiology before digital radiography was part of the didactic component of the student's education.


Needs Analysis

1.Instructional Problem- Digital radiography has only been prevalent in the capital district for approximately 10 years. Any technologist in the field that was educated before it became part of the didactic component of their degree is at a serious disadvantage over students today. When digital equipment is implemented into a radiology department, the company offers applications on the newly installed equipment as part of their purchase price. However, the focus of applications is on how to use the equipment and the computers systems that come with it but does not delve into the physical principles and technical details of the imaging system. This course aims to provide the seasoned technologist insight and understanding into the world of digital imaging.


2.The Nature of this Course - Learners of this course should take away a clear understanding of the physical principles of digital radiography. They will learn historical aspects of digital imaging, processing fundamentals, and theoretical foundations to use digital equipment effectively in the clinical setting.


3.The Learners- The learners in this course will be technologists that graduated from an accredited radiology program more than 10 years ago. These learners should be currently employed in the field of radiology so they will be able to take this newfound knowledge and implement it in the clinical setting.


4.Instructional Context- Most activities in this course will be conducted online and by the student. A technique lab activity will be made available after the course is completed.


5.Exploring the Problem and Solution- Learners will have the opportunity to apply their new-found knowledge to the clinical environment. Learners will explore the difference between analog radiography and digital radiography and why it is important to know the differences in technology.


6.Goals of this Course- For technologists to have a clear understanding of digital radiography and how it differs from analog radiography. For technologists to be able to apply their knowledge of digital radiography effectively in the clinical setting.

Performance Objectives

Upon completion of this mini-course students will be able to:

  • Define the term digital radiography.
  • Discuss the various types of digital radiography systems.
  • Describe the major technical componnents of a digital radiography system.
  • Describe the process of digital image data formation.
  • Describe the factors that affect digital image quality.
  • Explain critical elements used in different digital radiography systems.

Task Analysis

Course Purpose

The purpose of this course is to give seasoned technologists a better understanding of how digital radiography works and to give them tools to use and apply in the clinical setting.


Learning Outcomes

At the conclusion of this course students will be able to:

  • Define digital radiography and its critical components.
  • Explain the process of digital image formation.
  • Define the factors that affect digital image quality.


Pre-requisite Skills


Essential Pre-requisites In order to be successful in this course, students must have prior knowledge of:

  • Basic steps in the production of a radiograph.
  • Limitations of film-screen radiography.
  • Radiographic positioning.
  • Working knowledge of a CR/DR system.
