IIDS67531 Medical Image Acquisition 15 Semester 1 Postgraduate Taught Level 7 William Lloyd Unit coordinator Marie-Claude Asselin Unit coordinator Division of Informatics, Imaging and Data Sciences 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 At the end of this unit, the student will understand the principles behind the five major imaging modalities used in clinical practice: <ol><li>Conventional MR imaging (T1-, T2- and T2*-weighted and proton density)</li><li>X-ray, dual-energy X-ray absorptiometry (DEXA), conventional and cone-beam CT imaging</li><li>Conventional and Doppler ultrasound</li><li>PET</li><li>SPECT  </li></ol>For each of the imaging modalities, the basic concepts below will be covered:a) Image formation and reconstruction (including corrections)b) Impact of imaging parameters on image quality (including artefacts)c) Use of contrast agents (MRI, CT, ultrasound) or radiotracers (PET, SPECT)d) Clinical applications  At the end of this unit, the student will understand the principles behind the five major imaging modalities used in clinical practice:<ol><li>Conventional MR imaging (T1-, T2- and T2*-weighted and proton density)</li><li>X-ray, dual-energy X-ray absorptiometry (DEXA), conventional and cone-beam CT imaging</li><li>Conventional and Doppler ultrasound</li><li>PET</li><li>SPECT  </li></ol>For each of the imaging modalities, the basic concepts below will be covered:a) Image formation and reconstruction (including corrections)b) Impact of imaging parameters on image quality (including artefacts)c) Use of contrast agents (MRI, CT, ultrasound) or radiotracers (PET, SPECT)d) Clinical applications  The unit aims to cover the physical, mathematical and technological processes involved in a range of medical imaging modalities including magnetic resonance (MR) imaging, diagnostic X-ray imaging, computed X-ray tomography (CT), ultrasound, positron emission tomography (PET) and single-photon computed emission tomography (SPECT). The commonality between imaging systems will be emphasised and the clinical utilisation of images will also be covered.  A1-D7 refer to learning objectives in programme specifications. Students should be able to: 1.1Explain the key acquisition parameters which determine image contrast and signal-to-noise for the different modalities (A6, A7).1.2 Explain image reconstruction and corrections and their impact on image quality and artefacts for the different imaging modalities (A1, A6, A7).1.3 Appraise the effects of pharmacokinetics on image contrast and quality when using different contrast agents or radiotracers (A6, A7).1.4 Describe the clinical applications of the different imaging modalities (A3, A4).  Students should be able:2.1 Advise on choice of imaging modality for specific applications (B1, B2, B7).2.2 Advise on ways to improve contrast or signal-to-noise of images and appreciate the trade-offs involved (B5).  Students should be able to: 3.1 Use a narrow bore high field MR scanner to acquire and analyse data using image processing software (C1).  Students should be able to:4.1 Give an individual presentation on a medical imaging topic from reviewing the literature (D1, D2, D3, D7)4.2 Participate in group discussions of scientific results from the practical (D4, D5, D6).  Teaching involves lectures, tutorials and a laboratory practical session.Learning includes preparing two oral presentations, on the results of the MR practical and on an individually selected medical imaging technique.The course will be delivered as in person 10 x 2-hour lectures, each preceded by 1 hour of asynchronous material. One week will be served for the practical and another week for the individual oral presentations.Lectures will be reinforced by cross-modality 1-hour tutorials on different topics involving more than one imaging modality, some based on discussion of published papers.Exercises will be given at the end of each lecture via task-based learning. Solutions will be discussed prior to delivery of the following week material, so that students receive regular feedback.A practical on a preclinical MR scanner with a phantom where the effects of changing the acquisition parameters on the images and processing the data using different approaches will be investigated for different sequences. The students will present their results orally in pairs for group discussion.Another presentation will be prepared, this one summative and delivered individually, on a selected medical imaging technique, reviewing the published literature 1 Written exam 65% 7 Oral assessment/presentation 35% Further assessment details below: Formative - Group Presentation <ul><li>ILOs: 1.1, 2.2, 3.1, 4.2</li><li>Each presentation should be 8 minutes</li></ul>Summative - Presentation - 35%<ul><li>ILOs: 1.4, 2.1, 4.1</li><li>Each presentation should be 10 minutes</li></ul>Summative - Written Exam - 65%<ul><li>ILOs: 1.1, 1.2, 1.3, 2.2</li><li>1.5 hours</li></ul> Formative: Feedback will be provided within 1-2 weeksSummative: Feedback and marks provided within 3 weeks MSc Applied AI for Med Imaging MSc Applied AI for Med Imaging Not Set Mandatory N The material for this course comes from a variety of sources and is not available in a single reference text.
