Overview & Program

Workshop Overview

This workshop will address the growing interest in low field MRI (<1.5T). This workshop will be timely as more research is now underway at lower field (eg. Hyperfine system, ViewRay system, ramped-down clinical systems). The primary focus of this workshop will be on "high-performance" low-field MRI for specialized clinical applications, and the secondary focus will be on MR value/accessibility offered by low field.

Early in the development of MRI, there were debates on the “ideal” field strength, and the decision was dominated by the inherent SNR advantage of higher field. At that time, MRI engineering was immature, and by comparison, new low-field systems can benefit from modern magnet and gradient design, plus advanced image acquisition/reconstruction techniques, to recover SNR and imaging speed. Combining contemporary imaging techniques with unique clinical application opportunities and lower costs makes low field MRI attractive in clinical environments. This workshop will cover a breadth of topics in low field imaging, including:

  • Unique physical properties of low field;
  • Application of long readouts and novel k-space sampling to recover SNR;
  • Advanced image reconstructions and processing applied to low field;
  • Contrast agent performance;
  • Receiver array design for low field;
  • Flexibility in magnet design for low field;
  • MRI-guided interventions safely using commercial metallic tools;
  • MRI-guided radiotherapy procedures;
  • Imaging of patients with active and passive metallic implants;
  • Imaging near air-tissue interfaces (e.g., lung, airway, intestines, cranial sinuses);
  • Lower-cost system design for routine imaging; and
  • Point-of-care imaging.

The workshop will include invited talks, abstract presentations, a denoising challenge, and demonstrations of diagnostic and interventional MRI using high-performance low field MRI systems.

Target Audience: This workshop is designed for new MR scientists interested in learning and becoming involved in motion detection and correction; experienced researchers interested in meeting with fellow researchers to learn and share cutting-edge techniques for motion correction; clinicians interested in applying the latest correction methods to solve their motion problems; researchers interested in gaining information from motion; and industry representatives wanting to discuss the integration motion correction techniques with the standard MR platforms.

Educational Objectives

Upon completion of this activity, participants should be able to:

  • Describe the unique physical properties of lower fields;
  • Describe new clinical applications enabled by low field: interventional MRI, implant imaging, and near-air applications;
  • Describe the potential of low field for lower-cost system design; and
  • Describe engineering challenges at low field.
