MEDIMAGE 710 - CT Imaging Technology

15 Points

Next offered Semester 1, 2020



This course provides students with an in-depth understanding of CT technology and its application. The course addresses the scientific principles of the modality including image formation and reconstruction, technical parameters, radiation safety and dose reduction, image quality, artefacts, quality assurance and contrast agents. Equipment developments and new and evolving techniques will be examined.

Objectives and learning outcomes

This course aims to provide students with specialised theoretical knowledge and an understanding of the underlying scientific principles of CT technology. Students will develop the ability to apply this knowledge in the safe use of CT equipment for clinical and/or research purposes. This course will critically examine the selection of technical parameters and their relationship to image quality and to the use of sophisticated techniques in the acquisition of CT images. 

By the end of the course, students will be able to:

  1. Demonstrate an understanding of theoretical concepts relating to CT technology. 
  2. Critically discuss specific issues relating to bio-effects, radiation safety and dose reduction within the CT environment.
  3. Analyse and integrate the principles and technology of CT to enable image optimisation. 
  4. Critically evaluate the technical and diagnostic quality of a range of CT images. 
  5. Evaluate the importance of quality assurance and explain the associated impact on safety and image quality. 
  6. Critically discuss current developments in CT technology and explore recent literature in relation to emerging initiatives. 

Programme and course advice

This course is a compulsory course within the PGCertHSc(Medical Imaging – CT pathway) programme.

Students enrolled in the PGDipHSc/PGCertHSc (Medical Imaging) programmes may choose this course to contribute 15 points towards the MEDIMAGE/CLINIMAG point requirements.

Students from the PGDipHSc(MRI) and PGCertHSc (Mammography) programmes may choose this course as an elective. Students from the PGDipHSc (Medical Imaging – Nuclear Medicine pathway) programme are encouraged to choose this course as their elective.

All Medical Imaging Technologists and students admitted to any one of the above programmes are eligible for direct entry to this course. For all other students, departmental approval is required and a concession request must be submitted when applying to enrol in this course.

Access to a clinical CT department is highly recommended.

Course delivery and workload

The course is delivered fully online by distance via the University of Auckland’s learning management system Canvas. It will incorporate a range of learning approaches including videos, webpages, links to the library databases and resources, and utilising online technologies to promote shared learning opportunities.

The total expected workload for this course is approximately 150 hours. This may be broken down as follows:

  • Set readings relevant to CT theory (30 hours) 
  • Other resources provided on Canvas e.g. videos, websites (20 hours) 
  • Assignments and self-directed learning (100 hours)


Recommended textbooks

Computed tomography: Fundamentals, system technology, image quality, applications (3rd ed.), Willi Kalender, Erlangen: Publicis Corporate Pub. c2011

Computed tomography: physical principles, clinical applications, and quality control (4th ed.), Euclid Seeram, St. Louis, Missouri: Elsevier. 2016 

These books are both available in hardcopy from the Philson Library. In addition, a large selection of other readings and resources will be able to be accessed online via the course website and the Philson Library databases.

Pre-course reading

It is highly recommended that students access the online textbook ‘Medical imaging technology’ (2014) by Mikla and Mikla via the Philson Library and read ‘Chapter 2: Computed Tomography’ as pre-reading for this course. This will be assumed prior knowledge when you begin the course.
