MRI Ergometer Push/Pull
Unique imaging possibilities with patient in stress

This MRI ergometer is suitable for cardiology in scanners where it is impossible to make a real pedal movement. The workload is adjustable up to 100 watt. The zero load is <5 watt at 25 rpm. The MRI ergometer is an ergometer for use during MRI studies. The MRI ergometers workload is controlled with an electronical braking principle especially designed for use in a MRI environment. The moment of inertia is 8,4 kgm2. The MRI 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 wallfixation. The MRI ergometer can be used for MRI scanners up to 3 Tesla
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 social and environmental responsible company.
All Lode products are RoHS/WEE compliant.
Furthermore, Lode is ISO 9001:2003, ISO 13485:2008 and FDA 510K certified. All products comply the MDD 93/42/EEC standard, including IEC 60601-1.
Tesla independent
The choice of materials and the special design makes that the Lode MRI ergometer is useable for a 1,5 and a 3 Tesla MRI 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 at 1.5 and 3 Tesla
Compatible with
- Philips
- Siemens
- GE
Features
GE MRI compatible
The ergometer is compatible with various GE MRI devices
like Horizon, Twin Speed
Siemens MRI compatibility
The MRI Ergometer can be used in combination with the following Siemens MRI scanners Magnetom Harmony, Symphony, Sonata, Espree, Avanto.
Philips MRI compatible
The ergometer is compatible with various Philips MRI devices
like Philips Intera CV, Achieva 1.5 Tesla & 3.0 Tesla
Versatile controls
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
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.
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 have an electro-magnetic braking mechanism of Lanooy (eddy current). The biggest advantage of this braking system compared to a friction braking system is that it is more accurate. 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.
3 Tesla
Up till 3 Tesla
Virtually no interferentie up till 3 Tesla through smart constructions and material use

FAQ

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 - Are the Lode MRI ergometers compatible with MRI scanners of 3 Tesla

Yes, since January 2010 all Lode MRI ergometers are compatible with MRI scanners up to 3 Tesla
