Overview
Radiographers require a basic knowledge of general physics and more detailed theoretical background to the physical basis behind the equipment design, construction and materials and the increasing technological support for developing modalities. The aim of this unit is to provide you with an understanding of radiation physics related to x-ray production and radiographic practice and how radiation interacts with matter. You will learn about the basic physics of radiation and radioactivity, interaction of radiation with matter, radiation safety and the physics underpinning X-ray imaging. You will also acquire the basic knowledge of the physical principles of X-ray imaging and radiotherapy systems.
Learning Outcomes
On successful completion of this unit you will be able to:
- Explain the physical basis for the production of ionising radiation, and to describe the properties of ionising radiation which affect its behaviour in diagnostic imaging and therapeutic uses.
- Discuss how x-rays are generated, the design construction and materials used in the x-ray tube and high voltage generators.
- Describe the operation of radiotherapy x-ray tubes
- Manipulate equations and apply formulae to solve physics problems.
Content
Atomic structure, radioactivity, interaction of x-rays with matter.
Radiation dosimetry, radiation units, radiation detection.
X-rays - properties and nature.
X-ray tube construction and design. Diagnostic and therapy tubes.
High voltage generation, transformers, rectifiers, linear accelerators.
Ratings of x-ray tube, tube failure.
Learning Approaches
Lecture content will provide the knowledge base required for this unit and will be supported by tutorials enabling you to apply the theory covered in lectures.
Practical Experiences. Students will be carry out experiments involving radioactive decay, attenuation of ionising radiations, and electrical transformer behaviour.
Practical experiences: 1 practical experience per week for 4 weeks
Feedback on Learning and Assessment
Feedback will be provided to students verbally and in written form, Further consultation is available on request.
Assessment
Overview
You will be expected to undertake a number of assessments related to the learning outcomes of this unit (see below).
Unit Grading Scheme
7- point scale
Assessment Tasks
Assessment: Practical experiences
(Formative and summative) - Four practical experiences over 4 weeks will be conducted in the radiation laboratory. The experiences are designed to introduce you to basic concepts of radioactivity, attenuation of radiation, and electrical transformer circuits. Experimental data will be acquired, analysed and presented during the experimental session before being submitted through the use of a proforma that will be handed in at the end of each session for marking.
Assessment: Poster
As a radiographer or radiation therapist you may find yourself attending and presenting at conferences. A frequent way of presenting your work at a conference is the poster presentation. In this assignment, you will individually create a clinical poster presentation that applies radiation physics concepts to a real-world scenario relevant to radiography or radiation therapy. The goal is to demonstrate your understanding of key physics principles and their application in clinical practice. Your submitted digital poster will include a recorded 3 minute oral summary of the content of your poster.
Assessment: Final Examination
(Summative) - Invigilated examination of the content covered over the course of the semester. The examination could include a combination of multiple choice/answer and short answer questions.
Academic Integrity
Academic integrity is a commitment to undertaking academic work and assessment in a manner that is ethical, fair, honest, respectful and accountable.
The Academic Integrity Policy sets out the range of conduct that can be a failure to maintain the standards of academic integrity. This includes, cheating in exams, plagiarism, self-plagiarism, collusion and contract cheating. It also includes providing fraudulent or altered documentation in support of an academic concession application, for example an assignment extension or a deferred exam.
You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.
Breaching QUT’s Academic Integrity Policy or engaging in conduct that may defeat or compromise the purpose of assessment can lead to a finding of student misconduct (Code of Conduct – Student) and result in the imposition of penalties under the Management of Student Misconduct Policy, ranging from a grade reduction to exclusion from QUT.
