Introduction to Biomedical Imaging

Imaging technologies form a significant component of the health budgets of all developed economies, and most people need advanced imaging such as MRIs, X-Rays and CT Scans (or CAT Scans) during their life. Many of us are aware of the misinformation sometimes offered in TV dramas, which either exaggerates the benefits or overemphasizes the risks.

This medical imaging course provides an introduction to biomedical imaging and modern imaging modalities. The course also covers the basic scientific principals behind each modality, and introduces some of the key applications, from neurological diseases to cancers. This course includes modules specially designed for the general public, whilst also providing some advanced modules which could contribute to professional development in health, engineering and IT industries.

The Introduction to Biomedical Imaging course incorporates a case study which is introduced at the start of each episode. This case study will follow a hypothetical patient required to undergo various imaging modalities for a medical condition.

For each episode we include information relevant to that modality and the basic scientific principles, hardware and technology, and clinical applications.

• In episode 1, we'll consider x-rays.
• In episode 2, we'll explore computerised tomography (CT).
• In episode 3, you'll learn about ultrasound (U/S).
• In episode 4, we'll discuss magnetic resonance imaging (MRI).
• In episode 5, you'll learn about PET and SPECT.

Each episode will include several short quizzes which will not contribute to your final grade and will help you understand the key points.

To complete the course, the assessment is a marked quiz for each episode that will contribute to your final grade, plus a final assessment called Assessment Scenarios at the end of the course. Assessment Scenarios involve reviewing 2 case studies/scenarios and answering questions related to imaging modalities of relevance.
