Overview
This course is an accelerated MRI lecture covering the main principles behind MR physics and imaging for scientists and clinicians who do not have an existing knowledge of the topic or a training in physics or engineering.
Target Audience
The target audience includes clinicians and data scientists new to the field of MRI or who need to strengthen their knowledge in MRI fundamentals.
Educational Objectives
As a result of attending this course, participants should be able to:
- Define basic NMR and MRI principles;
- Describe conventional and more advanced acquisition strategies; and
- Identify and correct for basic artifacts.
| 13:30 |  | Basic MRI Hongxia LEI Keywords: Education Committee: Clinical MRI This session introduces some of MRI essentials, including MRI instruments, nuclear spin, Lamar frequency-resonance, magnetization/precession/rotating frame and T 1/T 2 relaxation etc. Conventional spatial encoding based on gradients and geometrical method for MRI are briefly covered. In summary, MRI requires a strong magnet, some nuclear spins and RF transmit and receive. With an RF applied on resonance, we can manipulate the magnetization vector. The resulting MR signal has two characteristic relaxation times – T 1 and T 2. With numerous spatial encoding methods, MRI can be obtained. |

| 14:10 | | k-Space & Data Processing Joseba Alonso Keywords: Physics & Engineering: Physics, Image acquisition: Reconstruction These slides are for an introductory course to k-space and data sampling. This teaching material has been designed for non-experts, and we have strived to keep mathematical formalisms to the bare minimum. |
| 14:30 | | Basic Sequences & Acceleration Strategies Reina Ayde |
| 14:50 | | Identifying & Correcting for Artifacts Michael Lipton Keywords: Image acquisition: Artefacts Common MRI artifacts will be reviewed to clarify their mechanisms and leverage this knowledge to identify and implement solutions to reduce artifacts that lessen image quality. Common artifacts will be classified based on the way in which they impact image quality. |
