Course Description:
This course introduces the student to the fundamentals of computed radiography (CR) and the principles of digital image acquisition and processing and its application in radiography. Emphasis is placed on image acquisition, optimizing image quality, image processing and image compression techniques, and the development of a QA/QC program. Topics include computer imaging basics, pixels and voxels, digital radiography hardware requirements, digital image processor, basics of computer radiography, concepts of direct digital radiography (DDR), image quality and quality assurance.
COURSE OBJECTIVES:
Following the completion of this course the participant will:
1. Discuss the historical aspect of the development of computerized radiography.
2. Define the following terms: byte, kilobyte, megabyte, gigabyte, and terabyte.
3. Describe the configuration of a digital image and digitalization.
4. Discuss the terms pixel, voxel, and their relationship to the digital image.
5. Describe a photostimulable phosphor.
6. State the ionizing range for photostimulable phosphors using radiation both electromagnetic and particulate.
7. Discuss how the gray scale seen with digital imaging is produced.
8. Calculate the number of pixels in a given matrix size.
9. Discuss image matrix and the meaning of gray-scale dynamic range.
10. List the components of a Central Processing Unit (CPU) and discuss their functions.
11. List the components of the digital image processor and discuss the application of each.
12. List the basic hardware components for digital radiography.
13. Compare and contrast digital versus conventional radiography.
14. Describe the process for each of the following: film digitization, digital fluoroscopy, computed radiography (CR) (-photostimulable phosphors), and Direct readout capture Radiography (DR) (-charged-coupled device (CCD), -indirect conversion, - direct conversion.
15. Define the term exposure index and discuss its role in technique selection by the technologist.
16. State the role of CR image capture into PACS for image display and storage.

ATTENDANCE:
Students are expected to access the website on a regular basis. It is advisable to spend a minimum of five hours per week in this coursework.
WORK ETHICS:
10 work ethics assignments must be completed and posted on the discussion board. These work ethics assignment can be found on the Discussion Board.
Other Requirements:
You must come to campus to take final examination.
CODE OF CONDUCT:
CHEATING:
The program’s policy for cheating specifies that one (1) incident of cheating will result in a grade of zero (0) for that examination and DISMISSAL FROM THE PROGRAM.
Cheating includes but is not limited to: Copying from the test of another student allowing another student to copy from your test. Possessing materials or objects not authorized by the instructor during the test, including “crib notes”, programmable calculators, open textbooks, notebooks or notes, even if unused. Copying, recording, buying, stealing, transporting or soliciting tests (pre or post testing), test keys, questions written assignments or computer programs. Seeking aid from or collaborating with another student for aid without permission from the instructor during a test. Discussing the test with a student who has not already taken the test. Substituting for another person, or permitting another to substitute for you. Alteration of scantron or any other grade sheets through changing answers or filling in of blank spaces after being graded
A student dismissed for cheating or plagiarism will not be eligible for re-entry.
Plagiarism is defined as copying someone else’s work and presenting it as one’s own, without the knowledge of the original author. All research due must give credit when quotes are used.
SAFETY:
Please refer to the OTC website: http://www.ogeecheetech.edu/student_services/campus_safety.html
DISTRIBUTION OF GRADES:
Evaluation of the student’s achievement of the course objectives will be based on satisfactory completion of all required activities. Grading to be computed as follows:
Weekly Assignments 32%
Article Reviews 25%
Unit Exams 40%
Comprehensive final exam 28%
Grading Scale:
