MRI Systems Engineering
Weekend Course

ORGANIZERS: Greig Scott, Ileana Hancu

 
Saturday, 11 May 2019
  08:00 - 17:00

Skill Level: Basic to Intermediate

Session Number: WE-02AB

Overview
This one-day educational course is targeted at scientists and clinicians interested in understanding the engineering of magnetic resonance systems on a subsystems level. In a series of lectures from experts in MR systems engineering, attendees will first be provided with an overview of an MR system and then learn about the design of magnet, gradients, and shim systems, as well as the operation of the radiofrequency (RF) electronic subsystems that interface with RF coils. Issues relating to the site preparation and installation of new MR systems will also be discussed. In addition, attendees will be taught about the key elements of MR safety as it relates to peripheral nerve stimulation (low frequency electromagnetic field interactions with the body) as well as energy deposition in the body from high frequency electromagnetic field interactions. The compatibility of medical devices and implants with an MRI scanner will be discussed. This course is aimed at scientists and clinicians with a technical background and interest in MR systems hardware. It is expected to provide attendees with an understanding of fundamental aspects of MR system operation.

Target Audience
Scientists and clinicians who are starting to work in the field of MRI and would like to have an overview of the engineering of an MR system. More experienced researchers in particular areas of MR engineering will also benefit from hearing about recent advances in the engineering of MR systems.

Educational Objectives
As a result of attending this course, participants should be able to:
- Discuss the basic subsystems hardware components of an MRI scanner, including how they interact and function;
- Describe issues related to installing a new MR scanner, including space, venting, power, and cooling considerations;
- Recognize practical limitations in the design and construction of magnets, gradients, and shim systems;
- Identify the basic mechanisms by which medical devices interact with the magnet and gradients within an MRI scanner;
- Describe the interactions of electromagnetic fields (both low frequency gradient switching and high frequency RF) with the human body; and
- Explain the RF electronic subsystems that interface with RF coils, including interactions between separate transmit and receive coils.
