G.E. Healthcare, Buckinghamshire, U.K., announced a partnership with West Sussex, U.K.-based Tesla Engineering Ltd. on the development of a new 7T whole-body MRI scanner.
The partnership will build on GE’s 10-year history of producing 7T MRI scanners, currently deployed in the U.S., Italy and Japan for medical and scientific research, primarily in morphological and functional imaging of the brain. In the U.S., G.E. has three 7T scanners installed, one each at Stanford University, the University of California, San Francisco and the Medical College of Wisconsin.

7T Magnet scanner has shipped and should arrive in Iowa on the 4th of June
ABSTRACT: Infancy and early childhood coincide with one of the most dynamic periods of brain development, plasticity, and learning. A key developmental process throughout this period is myelination, the establishment of the myelinated white matter, which facilitates rapid communication across the brain's eloquent networks and systems. Abnormalities in white matter development, leading to altered brain connectivity, are hypothesised to play an important role in many developmental, behavioral and neuropsychiatric disorders, such as autism, ADHD, and others. Unfortunately, little is known about the patterns of brain growth and white matter myelination throughout early childhood; how these patterns relate to functional maturation; or how they may be involved in various disorders. In this talk, we will describe an MR imaging method for specifically investigating myelination, and detail results from an ongoing longitudinal study of early brain development in healthy, typically developing infants and toddlers. Specifically, we will demonstrate the normative patterns of white matter myelination, detail associations between myelination and functional connectivity (derived using resting-state fMRI), as well as correlations between myelination and behavioral and cognitive maturation.
7T on schedule to be shipped on April 28.

On Thursday, November 10 the MRI Research Facility will host the first in a six-part lecture series dedicated to all things 7T. The objective of the lectures is to inform imaging researchers about the applications, challenges and benefits available at 7T. We also hope it spurs excitement and interest in imaging research. To kick the series off, we brought in three top researchers from the GE 7T program.
Jacques Coumans, PhD is the General Manager of GE's Premium MR Business and will give an overview of GE's MR business and premium product portfolio.
Rob Peters, PhD is the Manager of MR Physics and MSK Applications for the ASL Team at GE and will discuss Musculoskeletal (MSK) MR, the GE ASL organization, and the GE research collaboration process.
Greg Hurst, PhD is GE's 7T and High Field MR Product Manager and will talk about UHF MR technology, applications and the GE 7T research program. Please join us on Thursday, November 10 from 1:30 - 3:30 pm in the Urmila Sahai Auditorium, 2117 MERF.
The MRI Research Facility recently purchased left and right hand fiber optic response pads from Psychology Software Tools (creators of E-prime). The new response system is available at the the research 3T located at L169 MERF. The MRI Simulator is also outfitted with the response system.
Autumn Craig started Monday, April 18 as our part-time technologist at the MRI Research Facility. This addition to our research staff will allow us to expand our hours of operation and to accommodate a greater number of evening and weekend scanner requests. Autumn has worked as a technologist in the Department of Radiology for the previous 8 years, and has extensive experience conducting fMRI research scans as a backup technologist for our facility. Her experience and flexibility will play an important role in the success of our young imaging facility, and will be especially valuable as we begin to establish our ultra-high field 7T program.

On April 10, 2010, The University of Iowa held a NA-MIC (National Alliance for Medical Image Computing) sponsored 3D Slicer training workshop. Over 60 participants, with backgrounds ranging from Biomedical Engineering to Internal Medicine, attended the training. The workshop was divided into two sections that focused on 3D Slicer applications, and the development of 3D Slicer.
The National Alliance for Medical Image Computing (NA-MIC) is sponsoring a 3D Slicer
training workshop at the University of Iowa on April 9 and 10, 2010.
The format for the workshop will consist of a large presentation on
Friday afternoon, and two sessions on Saturday including a programming
tutorial session and End User training.
An updated version of the
Research Protocol Form is available on our Forms page. Please unsure this is the version that is filled out for every subject who receives a research MRI scan.
Construction has begun on the Iowa
Institute of Biomedical Discovery (IIBD) facility. The new building will
house 8 floors of dedicated research space, 198,000 gross ft2 of space, a 15,000 ft2 imaging facility and 15,000 - 30,000 ft2 dedicated to high-risk, high-gain product-orientated research.
The estimated completion date for the IIBD is late 2013. For more information visit The U of I Institute for Biomedical Discovery website.
Two additional pieces of equipment are now
available for general research usage at the L169 research suite in MERF.
MediGoggles, manufactured by Cambridge Research Systems, are
customizable prescription glasses that allow subjects who wear glasses
to safely participate in fMRI studies with visual stimuli. Learn more
about MediGoggles at our equipment page.
We also recently purchased the FOMRI II Dual Channel MRI Microphone System from MAGMEDICS. The FOMRI II system uses fiber-optic technology and an advanced set of noise-canceling algorithms to reproduce high quality speech from recordings within the MRI magnet.
The MR Research Facility recently installed the FerroGurard®Freestanding metal detector system by Metrasens.
The addition of the Ferroguard system will improve the quality
of our services by providing an additional measure of screening for
patients and subjects entering the MR scan room. Our subjects,
technologists and researchers can gain comfort from knowing an
additional screening measure has been performed on every patient,
ensuring only the highest quality of MR images are obtained. For more
information on the FerroGuard, visit Metrasens online.
Several new links have been added to the Facility Information section on the left
side of the page, including an "Images" page, an updated "Equipment" page, and
an updated "Contact Us" page with maps and directions to the MRRF.
Also of note is a "Research Projects" link, where researchers can learn
more about the current research projects here at the MRRF.
How to Find the MR Research Center - Maps and Directions
Links to the Research Scheduler, facility equipment, university
resources and more can be found at the left. In addition, a new "Contact Us"
link has been added for convenient access to the Research Center’s
personnel and imaging laboratories. We’re also currently adding
additional pages to the site, including neuro, ortho and cardiac images,
as well as a section dedicated to research news.
Scheduling for the new Research Trio 3T at L169 MERF is now
