Broadening horizons – impactful imaging across applications and field strengths.
6th Skope User Meeting: October 10th and 11th, 2023 - Minneapolis, MN, US
Welcome!
The 6th Skope User Meeting was held in Minneapolis, Minnesota, US, on October 10th and 11th, directly before the 2023 Minnesota Workshop on Ultra-High Field Imaging. This year, we focused on
Broadening horizons – impactful imaging across applications and field strengths.
The meeting started on Tuesday evening, October 10th, with a dinner session. On Wednesday, we continued with a scientific session, which showcased three guest lectures, trainee presentations, and updates on new Skope technologies. In the afternoon, we run interactive demo sessions.

Abstracts
Progress with field monitoring on a head-only 7T and full-body 3T MRI
Corey A. Baron, PhD
The Baron Lab has been developing approaches for robust field monitoring on a head-only 7T MRI located at the Centre for Functional and Metabolic Mapping (CFMM) since 2019 and has extended field monitoring to their 3T system earlier this year. This presentation will provide a tour of their progress with field monitoring so far, current projects, and perspectives on challenges that should still be solved to facilitate high-throughput studies.
Towards an era of precision MRI
Kawin Setsompop, PhD
In the last few years, there has been an emergence of new data acquisition technologies to help us move towards Precision MRI, or the ability to image the human body much more precisely with MR. With Precision MRI, the goal is to be able to obtain detailed quantitative tissue structural and functional information of the human body at the meso-scopic scale, while producing crisp images that are robust to system imperfections and motions. Exciting new information from Precision MRI should allow us to gain a much better understanding of the structure and function of the human body in health and disease states. This talk will describe some of the acquisition technology that is being developed in my lab towards precision MRI and how field-probe monitoring can play an important role in helping us achieve this goal.
Measuring and reducing background velocity errors in phase contrast MRI
Mike Loecher, PhD
Phase contrast MRI measures tissue velocity with the use of bipolar gradients. However, the additional fields created by these bipolar gradients due to eddy currents and mechanical oscillations also contribute to the measured phase, leading to background velocity errors in the data. In this work, we explore the source of these errors, measure the effects and responses with a Skope camera, as well as use the Skope system to generate a GIRF to predict and prospectively correct for these errors with gradient optimization techniques (GrOpt).
7T workflow – integrated acquisition technology for 7T neuroimaging
Demo Session 1
Combining the Cranberry Edition kit for hardware integration with skope-dm (data manager) we demonstrate the concurrent monitoring workflow which streams data from both the MR scanner and Skope Acquisition System. Learn how this new workflow improvement tool can be integrated into your scanning experiments. We will demonstrate the entire image acquisition and reconstruction workflow, from initial setup to finished DICOM data set.
Characterizing system performance with field monitoring – from impulse to image
Demo Session 2
System characterization is important to understanding system performance, especially when developing custom hardware or developing sequences which utilize the full extent of your hardware’s capabilities. In this demonstration, you will learn how direct measurements of field dynamics can be used to characterize system performance and how performance can correlate to image quality.
