ETS-Lindgren is one of the unsung heroes in healthcare, providing shielding solutions for facilities that house one of medicine’s most powerful diagnostic tools – Magnetic Resonance Imaging scanners.
Computerized MRI scanners, however, only provide reliable images if they’re shielded from the interference frequently found in urban and office environments, and this is exactly what ETS-Lindgren provides. Our specialized team is highly skilled at developing and assembling both passive and active shielding systems, as well as components, for new treatment rooms and retrofitted facilities. As the clear industry leader, ETS-Lindgren was recently tapped to help develop a new type of intra-operative suite that allows MRI scans and surgical procedures to be done in the same room. As healthcare imaging technology continues to advance, ETS-Lindgren will be there with products that ensure physicians can see and treat the human condition.
And, for more than 40 years, ETS-Lindgren has provided superior sound isolation solutions for audiology and related research. In addition to our in-house expertise, we have a comprehensive network of local sales and service experts. This local presence ensures our clients receive quick service, support, and maintenance for facilities focused on managing hearing health.
All shielding technologies are not equal and consideration of a host of factors should be given when selecting shielding, including performance requirements (E-Field, H-Field, Plane Wave, etc.), the application, quality of products, long-term performance, materials used, and construction methods.

ACTIVE MAGNETIC FIELD COMPENSATION SYSTEMS A COMPARATIVE STUDY
A study at The Ohio State University Wexner Medical Center describes shielding a high-sensitivity digital mammography system detector from AC magnetic fields of magnitudes great enough to induce imaging artifacts. Successful shielding addressed the EMI and removed the imaging artifacts.

Magnetic resonance imaging safety can be analogized to a three-legged stool. Anything less than an equal development of three distinct domains - clinical safety, operational safety, and physical safety - makes for a very precarious position.
When Chris Tomlinson, radiology imaging director at the Children's Hospital of Philadelphia, received complaints from other areas of the hospital about the loud noises from their MR scanners, he know something had to be done about it. "When you put an MR in, if you're not shielding it you can definitely have some complaints from neighbors - they may be on the other side of the wall or even on other floors," he says.
Intra-Operative MRI (iMRI) is quickly becoming the go to technology in the ever evolving integration of various radiologic modalities for invasive and non-invasive patient procedures and treatments. Intra-Operative MRI is defined by the use of an MRI magnet during a surgical or treatment procedure. This can be achieved with a moving magnet that is brought into the theatre or by moving the patient to the room containing the magnet. In both cases, imaging is performed prior to, during and after the surgical or treatment procedure. The real time availability of the high resolution MR images is improving patient outcomes in a widening arena including, but not limited to, neurosurgery, cardiovascular and radiation oncology. This article will provide an overview of current iMRI technology and review design, location, safety and performance considerations to ensure an optimally functioning iMRI facility. Following a successful installation, maintenance guidelines are provided to protect your iMRI investment for years to come of optimal imaging and patient care.

Intra-operative magnetic resonance imaging is quickly becoming the leading technology in the integration of various radiologic modalities for medical procedures. iMRI refers to the use of an MRI magnet during a surgical or treatment procedure either a moving magnet brought into the theater or by moving the patient to the room containing the magnet. In both cases, imaging of precise locations is performed prior to, during and after the surgical or treatment procedure.
