Tuesday, 25 April 2017
Room 313BC  07:00 - 07:50 Moderators: Fraser Robb, Jason Stockmann

Skill Level: Intermediate to Advanced

Slack Channel: #e_phys_eng
Session Number: STu09

This course is designed for physicists and engineers to provide an introduction to new or emerging MR methods and applications that are gaining interest. The session provides an overview of low field MR system technology, including how to design a portable MR system. Imaging considerations at low field, such as contrast behavior, SNR and artifact sources, will be discussed. Applications that benefit from low field - in particular hyperpolarization, pre-polarization and magnetic particle imaging - will be presented.

Target Audience
Those interested in: 1) understanding design considerations related to portable MR systems and learning about technology relevant for low field imaging; 2) understanding potential benefits and challenges of imaging at low field; 3) understanding the theory behind hyperpolarization, pre-polarization and magnetic particle imaging, and why these techniques benefit from low field.

Educational Objectives
Upon completion of this course, participants should be able to:
-Identify design considerations for low field systems and portable MR systems;
-Describe benefits and challenges related to imaging at low field; and
-Describe applications that particularly benefit from low field - in particular hyperpolarization, pre-polarization and MPI.

Low Field MR - System Design & Imaging Aspects - permission withheld
Clarissa Cooley
There has long been a push for higher field MRI systems to increase magnetic polarization and therefore SNR. However, the development of MRI systems at low-field (< 0.1T) and ultra-low field (< 10mT) could lead to an overall increase in the accessibility of MRI in terms of cost and portability.  An overview of low-field MRI system design and imaging aspects will be presented, and the advantages and disadvantages of low-field MRI compared to high-field MRI will be discussed.

Magnetic Particle Imaging
Emine Saritas
Magnetic Particle Imaging (MPI) is a new imaging modality first presented in 2005. While the acronym resembles that of MRI, MPI uses a completely different imaging hardware than MRI.  This presentation will cover the basics and imaging applications of MPI that include angiography, cancer imaging, and stem cell tracking, and will also discuss future directions for this promising technology.
