How ITEL DIAMAGS technology solved critical MRI magnetic interference challenges in clinical environments worldwide.

๐Ÿ‡จ๐Ÿ‡ญ Switzerland

Basel Institute

GE Open MR-Signa Ovation โ€” 0.35 Tesla
Site Problem

Continuous magnetic field fluctuations caused by a tram power line located just 30 metres from the test point exceeded GE's pre-installation limits on the vertical Z-axis. Maximum variations reached 40 mGauss peak-to-peak at low frequency (below 10 Hz), posing a direct threat to image quality and scanner stability.

The Solution

ITEL DIAMAGS Active Compensation System was deployed to counteract the tram-generated disturbances. High-precision fluxgate sensors detected field variations in real time, while Helmholtz-like compensation coils generated an opposing magnetic field to cancel out the interference dynamically.

Results After Installation
  • Tram-generated low-frequency fluctuations neutralized in real-time
  • B-field homogeneity restored โ€” ghosting and artifacts eliminated
  • Continuous dynamic protection throughout all operating hours
The implementation of ITEL DIAMAGS allowed the site to meet GE pre-installation specifications, ensuring the 0.35 Tesla MRI operates without diagnostic image degradation caused by external field variations.

Clรญnica del Rosario

GE Profile โ€” 0.2 Tesla ยท Madrid
Site Problem

Magnetic measurements at Clรญnica del Rosario revealed a severe three-axis interference crisis caused by a nearby metro power line. Variations significantly exceeded GE Profile 0.2T limits: Y-axis at 200.03 mGauss p-p, X-axis at 78.02 mGauss p-p, and Z-axis at 17.30 mGauss p-p โ€” making installation impossible without intervention.

The Solution

ITEL DIAMAGS Active Compensation System was configured for multi-axis sensing and compensation to address simultaneous disturbances across all three spatial planes. The system created opposing magnetic fields in real-time to cancel out the metro-induced environmental B-field variations.

Results After Installation
  • 200 mGauss vertical spikes suppressed to within GE tolerances
  • Multi-axis field stabilization achieved across X, Y, and Z planes
  • Electronically hostile environment transformed into a high-performance diagnostic suite
By installing ITEL DIAMAGS, the facility effectively compensated external DC variations across all axes, enabling full clinical operation of the GE Profile 0.2T system.

GE Esaote eScan โ€” 0.2 Tesla ยท New York
Site Problem

The Manhattan installation site for a GE Esaote eScan 0.2T faced a dual electromagnetic threat: a subway power line generating continuous vertical field variations up to 26 mGauss p-p, compounded by a densely trafficked urban environment. GE mandated specific site adjustments before installation could proceed.

The Solution

ITEL DIAMAGS Active Compensation System was installed to neutralize subway-induced field variations. A magnetic shield was applied to the partition wall between the MR room and the adjacent office area, and shock absorbers were installed to suppress vibrations from HVAC conditioning equipment.

Results After Installation
  • 26 mGauss vertical interference reduced to under 0.5 mGauss
  • Magnetic shielding on partition wall provided additional protection
  • Vibration dampers eliminated HVAC-induced mechanical interference
By neutralizing subway-induced field variations, ITEL DIAMAGS provided the stable magnetic environment necessary for high-fidelity diagnostic imaging, enabling trouble-free installation of the GE Esaote eScan 0.2T.

Lenox Hill Radiology

Hitachi Oasis โ€” 1.2 Tesla ยท Brooklyn, New York
Site Problem

Magnetic field measurements at Lenox Hill Radiology in Brooklyn revealed significant electromagnetic interference caused by the New York City subway system. Field fluctuations reached a maximum of 36 mGauss p-p, exceeding the susceptibility limits of the Hitachi Oasis 1.2T MRI and risking image artifacts, ghosting, and loss of diagnostic clarity.

The Solution

ITEL DIAMAGS Active Compensation System was deployed to counteract subway-induced disturbances. High-precision fluxgate sensors identified the exact nature of the fluctuations in real-time, while Helmholtz-like compensation coils generated an opposing magnetic field to cancel out the interference at the MRI isocenter.

Results After Installation
  • Subway-generated fluctuations identified and successfully neutralized
  • B-field stabilized โ€” ghosting and imaging artifacts eliminated
  • Hitachi Oasis 1.2T operating at peak performance in a challenging urban environment
The installation of ITEL DIAMAGS transformed a compromised facility into a viable, high-performance diagnostic suite, ensuring reliable patient outcomes against continuous subway disturbances.

Pelham Bay Professional Center

Philips Ingenia โ€” 1.5 Tesla ยท New York
Site Problem

Measurements at Pelham Bay Professional Center revealed continuous low-frequency magnetic field fluctuations caused by a metro railway located 200 metres from the MRI isocenter. Variations on the Z-axis reached 35 mGauss p-p โ€” significantly exceeding the Philips Ingenia 1.5T pre-installation limits and threatening image quality and operational stability.

The Solution

ITEL DIAMAGS Active Compensation System was selected to counteract the metro-generated disturbances. The system utilized high-precision sensors tuned to the specific low-frequency band of the interference, driving Helmholtz-like coils to generate a real-time opposing field and cancel out the B-field variations.

Results After Installation
  • Metro-generated low-frequency fluctuations neutralized in real-time
  • Z-axis field stabilized within Philips-specified tolerances
  • Philips Ingenia 1.5T fully operational with artifact-free diagnostic imaging
ITEL DIAMAGS allowed the site to meet Philips pre-installation specifications, ensuring the 1.5T MRI operates without diagnostic image degradation caused by external B-field variations.

Zwanger-Pesiri Radiology

Hitachi Oasis โ€” 1.2 Tesla ยท Elmhurst, New York
Site Problem

At Zwanger-Pesiri Radiology in Elmhurst, New York, maintaining a stable magnetic environment for the Hitachi Oasis 1.2T MRI proved extremely challenging due to the NYC subway system running nearby. Field fluctuations reached 38 mGauss p-p โ€” causing severe image artifacts, ghosting, and scan instability that rendered high-precision diagnostic imaging impossible.

The Solution

ITEL DIAMAGS Active Compensation System was installed to combat the subway interference. The system continuously sensed incoming disturbances and instantly generated an equal and opposing magnetic field, keeping the MRI environment within Hitachi's tight susceptibility tolerances at all times.

Results After Installation
  • Subway-induced spikes reduced below Hitachi's maximum susceptibility limit
  • Clear, diagnostic-quality images restored without subway interference
  • Continuous active protection ensuring peak MRI performance in an urban setting
ITEL DIAMAGS transformed a compromised site into a stable clinical environment, allowing Zwanger-Pesiri Radiology to operate the Hitachi Oasis 1.2T at full performance with reliable patient outcomes.

Casa di Cura Madre Fortunata Toniolo

Philips 5300 โ€” 1.5 Tesla ยท Bologna
Site Problem

At Casa di Cura Madre Fortunata Toniolo in Bologna, a private road running directly above the MRI room โ€” with passing cars just 4 metres from the isocenter โ€” generated continuous low-frequency horizontal field fluctuations reaching 25 mGauss p-p on the Z-axis, well beyond Philips 5300 1.5T pre-installation tolerances.

The Solution

ITEL DIAMAGS Active Compensation System was configured to counteract the car-passing-generated fluctuations. Tuned to the specific low-frequency band of the disturbance, the system's sensors and Helmholtz-like coils created a real-time opposing field to neutralize the interference before it could affect the MRI scanner.

Results After Installation
  • Car-induced low-frequency fluctuations identified and neutralized in real-time
  • Z-axis field stabilized within Philips-specified tolerances
  • Philips 5300 1.5T operating with full diagnostic image quality
ITEL DIAMAGS allowed the site to meet Philips pre-installation specifications, ensuring the 1.5T MRI operates without diagnostic image degradation despite the uniquely challenging road-above-scanner configuration.
