MR Ergometer Pedal
Medication free, load adjusted patient activation during MR scans
The MR ergometer is an ergometer for use during MR studies. The MR ergometers 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 control unit and power unit. The standard control unit offers the possibility to read out various parameters like workload, rpm, torque, timer and distance. The power unit is completed with a safety cable for wall fixation. The MR ergometer can be used for MRI scanners up to 3 Tesla.
A unique ergometer
Overview
Highlights
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, ISO and 13485:2016 certified. All medical products comply to MDD 93/42/EEC, incl. IEC 60601-1.
Compatible with various MRIs at 1.5 and 3 Tesla
Compatible with
– Philips
– Siemens
– GE
– Philips
– Siemens
– GE
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.
Features
Extreme low start up load
The extreme low start-up load of 7 watts and the adjustability in small steps of 1 watt make this ergometer perfectly suitable for many different applications. The standard control unit shows multiple ergometry parameters and you can determine your specific default setting and start-up menu.
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.
like Philips Achieva and Ingenia.
Additional features with PCU
Besides the possibility to program 24 protocols easily, this control unit offers the following features:
– better monitoring because of the additional and larger display
– a perfect combination with BPM
– possibility to measure SpO2
– better monitoring because of the additional and larger display
– a perfect combination with BPM
– possibility to measure SpO2
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 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.

Q - Is it possible to use the MRI ergometer with all kind of MRI scanners?
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)
Q - Can I change the contrast of the display on my Lode bicycle ergometer?
Your Lode ergometer is standard supplied with one display. The contrast of this display is factory set and can adjusted by qualified service personal only. If your ergometer is supplied with a programmable option the contrast of this display can be set as follows: go to SYSTEM PARAMETERS select SETTINGS go to CONTRAST. Change the visability according your wishes and save the changes.
