SUPPLIERS AREAINTRODUCTION
From the first full-body scanner in 1977 to the present day, magnetic resonance imaging (MRI) technology has evolved significantly, moving from stationary equipment to portable solutions. Non-magnetic coaxial connectors play a key role in this advancement.
USE OF RF COILS
In MRI systems, RF (Radio Frequency) coils can be:
Volumetric coils for whole-body imaging.
Surface coils for imaging specific areas of the body.
Multi-channel coils can have up to 32 surface coils.
The coils are subjected to a magnetic field inside the MRI equipment.
Non-magnetic connectors are used to transmit the radiofrequency signals received by the patient coils to the MRI system.
Surface coils collect the magnetic signal.
Coaxial cables and connectors transmit the radio frequency signal.
The coaxial cables connect to a common input board, connected to the MRI system via a multi-coaxial backbone cable.
ADVANTAGES OF NON-MAGNETIC CONNECTORS
- They allow a homogeneous magnetic field, which translates into high-resolution images and a better signal-to-noise ratio.
- Low magnetic susceptibility, avoiding distortions, shadows or spots in the images.
- Completely “transparent” to the magnetic field.
EXPERIENCE AND LEADERSHIP
Radiall was one of the first manufacturers to produce high quality guaranteed non-magnetic coaxial connectors.
Since 1998 it has supplied millions of units, including:
- Non-magnetic coaxial connectors.
- Non-magnetic cable assemblies.
- Multi-port and mixed-contact assemblies.
CUSTOMER SERVICE
We offer standard and customized solutions, from the design phase to post-installation support, with rapid prototyping, pre-series manufactured 100% in-house, and optimized production processes to reduce costs.
SPECIALIZED MANUFACTURING PROCESS
- Rigorous selection of raw materials.
- Dedicated production tools.
- Quality controls at every critical stage.
- Careful packaging and shipping.
NO MAGNETISM GUARANTEE ON OUR CONNECTORS
- The relative distortion of a 1.5 T magnetic field generated by a non-magnetic connector must be less than 5*10 -7 (0.5 ppm) at a distance of 10 mm from the connector surface.
- Minimal distortion of the magnetic field, the level of magnetic susceptibility (~10 -5 ) is very low.
- Quality control at every critical step of the process.

In order to support a market where technology is evolving rapidly and high-speed data is required, Radiall has developed SPnT switches up to 40 GHz controlled by a USB interface for quick installation and easy use. They offer excellent RF performance and reliability of up to 5 million cycles. 
Rather than offering standard cables with reinforced jackets and cosmetic changes, at Radiall we design TestPro cables and connectors from end to end to meet high performance requirements and address customer concerns when performing RF measurements. The TestPro range is the perfect solution for Test & Measurement applications where high precision quality, high flexibility, and phase and bending loss stability are required. 
Specialising in RF microwave passive components, Radiall develops and manufactures a wide range of microwave coaxial components including terminations, attenuators, couplers, power dividers, filters and other specialist components . Our range covers a broad spectrum of frequencies from DC to 67 GHz as well as low to high power, specifically designed for military, instrumentation, telecommunications and aerospace applications. Should you require a custom RF microwave component, Radiall’s engineering team will be able to design the best solution for your application. 
Semi-rigid cable assemblies are available as formed assemblies.
EZ-Lux™ is a multi-purpose single fiber connector capable of maintaining excellent optical performance even in harsh environments. It features an easy-to-mate push-pull locking system to speed up single fiber connection even under blind mating conditions. EZ-Lux™ is ideal for systems in dynamic environments requiring high-speed transmission within a small, lightweight connector.
