MRI Coil Mounting Brackets

Name: MRI RF Coil Brackets & Imaging Signal Mounts – Frigate
Price: 249.00 USD
Availability: InStock

The MRI Coil Mounting Brackets ensures submillimeter positional accuracy of receiver coils, critical for preserving spatial fidelity in serial or functional MRI scans. Mechanical instability beyond 0.1 mm introduces signal heterogeneity, phase shifts, and alignment errors across time-sequenced acquisitions. The bracket is precision-machined to ±0.02 mm tolerances, with rigid 3D reference planes and six-point constraint mechanisms that eliminate rotational and translational degrees of freedom.

Material Specification

Thread Specifications

M4–M8 (Metric), UNJF-3B (Titanium), Thread Pitch – 0.7mm ±0.01mm

Heat Treatment

Stress-Relieved (Per AMS 2750), Solution Treated & Aged (Ti, ASTM F136)

Product Description

The MRI Coil Mounting Bracket is engineered with embedded vibration isolation features to decouple ambient mechanical oscillations from sensitive RF coil assemblies. Undamped low-frequency vibrations originating from table drives or gradient coil switching can induce microphonic noise in receiver pathways. By incorporating elastomeric mounts tuned to attenuate structural modes between 5–100 Hz, the bracket suppresses resonance transfer and maintains coil stability during active scanning.

Coating/Surface Treatment

Anodized (Al, MIL-A-8625), Passivated (Ti, ASTM F86), Non-Conductive Coating (Optional)

Certification Standard

ISO 13485, IEC 60601-1-2 (EMC), ASTM F2503 (MRI Safety), ISO 10993-1 (Biocompatibility)

Flatness/Parallelism

Flatness ≤0.05mm/m, Parallelism ≤0.02mm, Perpendicularity ≤0.03mm

Hole Location & Diameter

±0.05mm (Hole Position), H7 Tolerance (Bore Diameter), Counterbore Depth – ±0.02mm

Inspection Method

100% CMM (±0.01mm), Thread Gauge (Go/No-Go), Visual (10x Magnification, ISO 14971), Lot Sampling (AQL 1.0)

Technical Advantages

The MRI Coil Mounting Brackets supports modular coil array configurations through a reconfigurable support system with indexed guide rails and precision detents. Clinical workflows that transition between neuro, musculoskeletal, and abdominal protocols require frequent coil changes without recalibration. The bracket includes angular and translational locking stops with laser-etched fiducials, ensuring accurate repositioning while preserving the system’s calibration matrix. This capability enables rapid adaptation to varied anatomical regions while maintaining consistent electromagnetic and geometric performance.

Designed for high-throughput imaging environments, the MRI Coil Mounting Brackets incorporates a quick-detach architecture to enable rapid coil removal without compromising system alignment. Dual-action mechanical latches combined with magnetic positioning features allow tool-less disassembly within seconds. Materials such as reinforced polyoxymethylene with stainless locking interfaces are used to ensure durability across repeated handling cycles. The bracket maintains consistent datum reference points, allowing reinstallations without mechanical or positional recalibration.

Industry Applications

Neuroimaging Systems

Supports rigid fixation of head and neck coils for accurate spatial registration in high-resolution fMRI and diffusion-weighted imaging protocols.

Cardiac MRI Platforms

Maintains stable coil positioning during ECG-gated imaging to minimize respiratory motion artifacts and preserve temporal signal coherence across multiple frames.

Musculoskeletal Imaging Suites

Provides modular coil support for variable limb anatomies, enabling accurate joint localization during dynamic or load-bearing orthopedic scan sequences.

Whole-Body Oncology Scanners

Facilitates consistent alignment of torso coils during multi-station body scans, ensuring repeatable signal uniformity in longitudinal cancer staging studies.

Pediatric MRI Configurations

Offers adaptable coil mounting for small-field imaging where high SNR and minimized coil-patient distance are critical for diagnostic performance.

Spine Imaging Systems

Ensures stable posterior coil positioning along cervical-thoracic-lumbar regions to preserve sagittal plane alignment during spine and disc integrity evaluations.

Continuous Electromagnetic Shielding Pathways

The MRI Coil Mounting Brackets integrates continuous EMI shielding channels to eliminate RF leakage pathways that may disrupt image quality. Discrete metallic interfaces are bonded using low-impedance conductive gaskets and shielded hinge lines to preserve electromagnetic continuity. Electrical resistance across mating surfaces is maintained below 0.1 ohms, verified via TDR and impedance spectroscopy.

All structural and fastener materials used in the MRI Coil Mounting Brackets are selected to ensure magnetic neutrality under static and switched field environments. Fabrication uses non-ferromagnetic alloys (e.g., 6061-T6 aluminum), high-performance polymers such as Ultem® and carbon-reinforced PEEK, and non-magnetic stainless components. These materials exhibit zero magnetic susceptibility and minimal induced force behavior, confirmed per ASTM F2052 and F2213 standards.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure bracket rigidity under dynamic table motion in MRI systems?

Frigate designs MRI Coil Mounting Brackets using high-rigidity materials like anodized aluminum and carbon-filled PEEK. The structure is validated through finite element simulations under axial and torsional loads to assess deflection. Multi-axis constraint points prevent mechanical drift during patient table movement. This ensures positional integrity of coil elements across all scan planes.

What measures does Frigate take to prevent EMI issues at the bracket-coil interface?

Frigate integrates continuous RF shielding paths with conductive gasket seams to maintain low-impedance electrical continuity across the mounting bracket. TDR and EMI compliance testing are performed during qualification to verify shielding effectiveness. The bracket is designed to suppress RF leakage near critical frequencies like 63.86 MHz and 127.72 MHz. This reduces noise coupling and preserves SNR in high-field imaging.

Can Frigate’s MRI Coil Mounting Brackets be customized for research-grade coil geometries?

Frigate provides custom mechanical interfaces that accommodate non-standard research coil arrays used in preclinical and experimental MRI systems. Modular brackets can be adapted with adjustable rails and angular stops. Precision machining tolerances are maintained even in low-volume prototypes. This supports electromagnetic boundary control in variable coil configurations.

How does Frigate control thermal deformation of the MRI Coil Mounting Bracket during long scan sessions?

Frigate selects materials with matched thermal expansion coefficients relative to common coil housing substrates. The bracket undergoes thermomechanical testing up to 40°C ambient temperature to simulate high-SAR conditions. Deformation is analyzed using FEA to ensure under 5 µm drift in all axes. This prevents misalignment during extended imaging protocols.

How does Frigate validate the MRI Coil Mounting Bracket’s compatibility with 3T and 7T systems?

Material compositions are tested for magnetic susceptibility and induced displacement per ASTM F2052 and F2213 standards. Frigate ensures no ferromagnetic response under strong B₀ fields. Mechanical and RF tests are also conducted inside actual 3T and 7T environments during qualification. These steps confirm bracket performance in ultra-high-field imaging platforms.
