Radiography: Principles and Positioning (CHI441)
|Organisational Unit||Psychology, Counselling, Exercise Science and Chiropractic|
|Teaching Timetables||Murdoch S2
|Description||Expands on principles discussed in Years 2 and 3 relating to image production for most common types of imaging modalities and essential knowledge and skills needed for producing high quality diagnostic radiographs. Covers principles of radiation biology, regulations and practices relating to safety and patient protection; addresses management of in-house radiographic facilities. Practical workshops focus on radiographic positioning for all anatomical regions relevant to chiropractic practice. Utilises equipment in preparation for application within the University's chiropractic clinic. Incorporates undergraduate research stream.|
|Unit Learning Outcomes||On successful completion of the unit you should be able to:
1. Identify all components of the x-ray system, and explain their function within the imaging process;
2. Explain the basic principles of radiation and x-ray production;
3. Describe fully the common types of interactions of diagnostic x-rays with matter, and how these create or degrade the final image;
4. Discuss the concepts of grids, collimation, and filtration, including how they relate to image quality and patient protection, and apply these concepts to the clinical setting;
5. Discuss the different types of imaging screens and film, how they are used, and their relationship to each other;
6. Consistently apply the concepts of image quality control to initial image acquisition;
7. Assess image quality in different clinical situations and institute the necessary changes to improve quality;
8. Show ease of use with the functions and operation of radiographic and processing equipment;
9. Demonstrate an ability to consistently and accurately integrate all sequences in the process of acquiring radiographic imaging of all musculoskeletal body regions, including skull and chest;
10. Explain the biological effects of radiation in humans as discussed in class;
11. Safely and consistently apply the concepts of radiation safety and patient protection in the clinical setting, including being able to confidently inform patients of radiation safety issues;
12. Operate x-ray facilities which meet State and Commonwealth standards;
13. Discuss the basic principles that underlie the common special imaging procedures, and the radiation safety issues that apply to each procedure.
14. Complete the required milestone for the research streaming project.
|Timetabled Learning Activities||Lectures: 3 hours per week; Laboratory: 2 hours per week; Directed Learning: 1 hour per week.|
|Unit Learning Experiences||Radiography is a diverse topic, with both theoretical and practical applications. As opposed to the radiology-related units you have taken to date, this unit has less to do with image interpretation, and more to do to with image production, quality assurance, and patient safety. You will therefore need to develop a different knowledge and skills base, but one that will complement what you have already developed and round-off your general information and skills base for imaging.
Much of the theoretical information you will learn in lectures will directly apply to the practical component of the unit in the labs. As such, you must be up-to-date with your theory in order to understand the various practical applications. Radiographic positioning requires the consistent and correct articulation of multiple skills to perform the process smoothly and accurately. Minor mistakes in any of the sequences can have profoundly negative implications to the final outcomes - the actual image and the patient radiation dose. Deficiencies in this skills-set are difficult to hide. In order to aid your learning, 3 radiographic systems will be used to allow you to gain hands-on experience with radiographic positioning in a simulated learning environment.
|Other Learning Experiences||In addition to the scheduled lecture and lab times, and the usual reading and study time, you will need to put in practice time on the radiographic equipment to develop your patient positioning skills. This cannot be postponed towards end of semester exam time, as you will have great difficultly developing the necessary skills in a short period. Open access to non-x-ray-producing equipment in the radiology lab is available for this purpose. The clinic radiography equipment is available for supervised training.

|Prerequisites||Enrolment in Chiropractic Science + Clinical Chiropractic (BSc, BClinChiro), and successful completion of Years 1 to 3, as well as CHI440 and CHI456, or permission of the Unit Coordinator.|

|Internet Access Requirements||Murdoch units normally include an online component comprising materials, discussions, lecture recordings and assessment activities. All students, regardless of their location or mode of study, need to have access to and be able to use computing devices with browsing capability and a connection to the Internet via Broadband (Cable, ADSL or Mobile) or Wireless. The Internet connection should be readily available and allow large amounts of data to be streamed or downloaded (approximately 100MB per lecture recording). Students also need to be able to enter into online discussions and submit assignments online.|
