MR Ergometer Pedal Ultra

Medication free, load adjusted patient activation during MR scans

The MR ergometer is an ergometer for use during MR studies. It can be used in a variety of MR scanners. The MR ergometer workload is controlled with an electronic braking principle especially designed for use in a MR environment. The moment of inertia is 8,4 kgm2. The MR ergometer is standard supplied with a 3.5” display and power unit. The display offers the possibility to read out the rpm and workload and is supplied with an optical cable. The communication module makes it possible to control the ergometer with the optional LEM software. 


Since all moving parts in the magnetic field are non-metallic and non magnetic, the zero load is not increased even when pedalling in the bore of the scanner. The ergometer is fitted to the patient support with a brand- and support-specific adapterframe. Options are available to control workload from the MR control room.


Unique ergometer for MRI

With this unique ergometer it is possible to perform an exercise test in an MRI. An ergometer on the tabletop of an MRI ensures minimal time stress induction and imaging without coursing artifacts on the imaging.

High standards

Lode is a socially and environmentally responsible company. All Lode products are RoHS/WEE compliant and Lode is ISO 9001:2015, and ISO 13485:2016 certified. All medical products comply to MDD 93/42/EEC, incl. IEC 60601-1.

Tesla independent

The choice of materials and the special design makes that the Lode MRI ergometer is useable for various Tesla MRIs without giving artifacts on the imaging.

Exercise instead of medicine

When a test subject is able to do exercise, it is always recommended above pharmacologic stress. It allows objective measurement in either level of cardiac conditioning and/or level of cardiac work. It is safe and perfectly reproducible.

Compatible with various MRIs

Compatible with
- Philips
- Siemens
- GE


GE MRI compatible

The Lode MR Ergometer is compatible with GE Signa and Discovery scanners.

Siemens MRI compatibility

The MRI Ergometer can be used in combination with many Siemens Magnetom MRI scanners, like Skyra, Aera, Verio, Essenza, Prisma, Avanto Fit, Vida, Sola, Altea, Lumina and Spectra.

Philips MRI compatible

The ergometer is compatible with various Philips MRI devices
like Philips Achieva and Ingenia.

Low noise

Due to accurate manufacturing and the careful choice of materials the product has an extremely low noise level.

Accurate over a long period of time

The Lode ergometers are supplied with an electro-magnetic braking mechanism of Lanooy (eddy current). The biggest advantage of this braking system compared to a friction braking system is the absolute accuracy and the accuracy over time. Moreover, friction braking systems have more wearing parts.

Small adjustment steps

The workload of the Lode ergometers is adjustable in steps of only 1 watt. Depending on your wishes, the test operator or the test subject can adjust the workload. The steps of 1 watt are possible in the manual mode as well as within protocols.
Service friendly

Service friendly ergometer

Lode ergometers are very service friendly. In general, total costs for spare parts are so low that they are negligible. Furthermore, most options are so easy to install and firmware is so easy to update that labor costs are minimal. Moreover, the ergometer can be cleaned easily.

LEM compatible

This product can be used with Lode Ergometry Manager (LEM) software to manage data and to apply specific protocols when a Communication card is present

USB connectivity

USB to connect to PC or ECG or ergospirometry products facilitates easy connectivity.

The MRI ergometer is compatible with Siemens, GE and Philips MRI scanners. The type of movement (up-down, push-pull or circular) is depending on the diameter of the scanner and the kind of research (cardiac, spectroscopy etc)
Yes, since January 2010 all Lode MRI ergometers are compatible with MRI scanners up to 3 Tesla
Yes, Due to the fact that the scientific research on the spread of Covid-19 is not yet conclusive Lode recommends to disinfect and clean all Lode products and their accessories (cuffs, heart rate belts, SpO2 sensors, handgrips/rails, touchscreens etc) that are in contact with the patient and or the medical personnel with a standard disinfectant as used in the hospital before and after every patient, with attention and care!

Since these agents are sometimes aggressive it might be advisable to check the effect on sensitive surfaces, like cushioning on non-visible areas. Lode will not take responsibility for discoloration due to these agents.
