"Field monitoring: Directly measuring the dynamic field within the MR scanner to improve image quality"

The scanner’s dynamic field (gradients and transient fluctuations) directly influences image quality. Transient field fluctuations caused by system non-idealities and physiological coupling to scanner can lead to the distortion of image geometry, loss of SNR, and ghosting artifacts. Field monitoring via NMR field probes presents a novel opportunity to directly measure the dynamic field. Dynamic field measurements can be incorporated into MR methods development, image reconstruction, or neuroscience research projects. MR methods development utilizes field monitoring to characterize and validate new hardware and pulse sequences. Image reconstruction utilizes field measurements to improve image geometry, SNR, or to enable new imaging modalities. Neuroscience can utilize field monitoring to improve the reconstruction of standard or novel imaging sequences for fundamental and translational research. This talk will present an introduction to field monitoring and demonstrate example applications including diffusion and 7T T2* weighted imaging.

 Cameron Cushing is an Application and Business Development Specialist for Skope MR Inc. Prior to starting at Skope, Cam obtained his PhD in Free Radical and Radiation Biology in the Radiation Oncology Department at The University of Iowa where he demonstrated that T2* relaxometry and QSM are sensitive to iron redox state and that changes in iron redox state can be visualized in ascorbate therapy for GBM. His current work focuses on developing field monitoring for neuroscience and neuro-oncology, with a focus on in vivo and high-resolution diffusion
