MR Ergometer Pedal Ultra
Medication free, load adjusted patient activation during MR scans
The MR ergometer is an ergometer for use during MR studies. 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 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 in a variety of MR scanners, even up to 7 Tesla!.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.
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 9001:2003, ISO and 13485:2008 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.

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 or Network card is present
USB connectivity
USB to connect to PC or ECG or ergospirometry products facilitates easy connectivity.
