MR-compatible Products

We bring medical products to MRI without detours

One of AcesoMed’s core competencies is non-magnetic medical technology suitable for MRI.

In order to obtain artifact-free images by means of magnetic resonance imaging (MRI) and to ensure a safe examination procedure, it is necessary to use medical devices specially designed for this application.

Devices for use in MRI must meet three functional requirements:

They must not be attracted by the strong magnetic fields in the MRI.
They must function properly in the MRI.
They must not interfere with the imaging of the MRI scanner.

WE BRING YOUR DEVICE TO THE MRI

Here’s how we ensure MR-compatibility of medical devices

The development of non-magnetic devices poses major challenges to the world of medical technology. AcesoMed specializes in the exceptional requirements of magnetic resonance imaging and offers its customers reliable development of MR-compatible medical devices. The following fields of competence are of particular importance.

Piezo motors and alternative actuators

Precise control of unconventional drives

In order to design an MR-compatible device, we do not use electric motors, as their ferromagnetic components are unsuitable for use in MRI. We are experts in using alternative actuators such as shape memory alloys, dielectric elastomers, and piezomotors, for example in the form of traveling wave motors.

Driver circuits

Efficient generation of high voltage signals

Piezomotors and dielectric elastomers are operated at high voltages. We provide these voltages in MRI with non-magnetic transformers and develop driver circuits for piezomotors.

Voltage transformers

Stable power supply in the external magnetic field

In many medical electrical devices, voltages have to be converted. In ordinary medical devices, transformers can be used for this purpose; in MR-compatible devices, this is not possible due to the iron cores. We develop non-magnetic voltage transformers without ferromagnetic components.

Verification of MR-compatibility

Trouble-free operation with full functionality

According to IEC 62570, ASTM F2503-05, and the FDA Guidance “Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment”, medical devices can be “MR Safe”, “MR Unsafe” or “MR Conditional”. We verify MR compatibility and perform tests according to ASTM F2052 and other relevant standards together with external testing laboratories.

MR-safety and risk management

Reliable safety concepts for MRI

We give top priority to the safety in the MRI environment of the medical devices we develop. Thanks to comprehensive risk management, we ensure compliance with strict requirements. Major risks include magnetically induced attraction and torques, electromagnetically induced heat, vibrations, induced electrical voltages, device malfunctions and imaging artifacts.
