ETS-Lindgren Optimizes MRI Services at Leading New York Hospital

Novel MACS™ Product Triumphs Subway Impact

CEDAR PARK, Texas, February 4, 2010 – ETS-Lindgren successfully completed installation of its Magnetic Active Compensation System (MACS™) at the Beth Israel Medical Center in New York City – to the relief of its patients, doctors and administrators. The MACS provides a maintenance-free, dynamic method for shielding MRI systems from low frequency environmental AC/DC magnetic interferences. In the case of the Beth Israel Medical Center, the interference to their magnetic resonance imaging (MRI) system was due to subways located under the hospital site. This interference adversely affected the quality of the images produced in the MRI suite and limited the doctors’ ability to accurately diagnosis patients. Hospital administrators were frustrated that the expensive magnet purchased for the hospital could not be fully used as intended.

Fortunately, ETS-Lindgren’s MACS product line results in a site environment that allows full use of all the functions available on an MRI system. In a big city environment, there are many potential sources of interference that may cause an adverse effect on an MRI system, such as the subways near the Beth Israel Medical Center, or transformers, elevators and moving vehicles. The MACS protects the MRI system from these sources of interference by providing high performance and reliable environmental shielding.

“Without the MACS, our staff at the Beth Israel Medical Center was only able to accommodate specific, limited cases. This resulted in restricted use of the MRI, especially during rush hour,” said Marc Katz Corporate Director, Department of Radiology for Continuum Services. “Now, with the MACS installation, the staff can address the needs of all types of patients with no limitations on the part of the MRI system,” he added.

Joel Kellogg, ETS-Lindgren’s Manager, Technical Engineering and Consulting noted, “The Beth Israel installation was especially challenging as there were very significant electromagnetic interference (EMI) disturbances created by the subway system. The disturbances were in excess of 300mG at times and needed to be reduced to about 4mG over the length of the MRI bore. We were confident the MACS installation would correct the problem and result in improved performance of the magnet.”

The MACS is ideal for large cities or any area with a dense population. The system provides the user with greater flexibility in MRI site selection and the ability to use any magnet – from 0.2T to 3T and higher - to its full potential regardless of the sources of AC/DC magnetic interferences. In addition, the MACS negative feedback technology corrects itself even as the environment changes. That frees users from actively monitoring the MRI environment and worrying about the adverse affects of interference on the quality of the images. To ensure a successful MACS installation, ETS-Lindgren personnel will often take detailed measurements on site prior to installation. This guarantees the MACS will address an accurate representation of the MRI environment.
