MR Ergometer Dorsal Ankle Flexion

MR Ergometer Dorsal Ankle Flexion

Show the calf while being activated in an MR Scanner
MR Ergometer for spectroscopy of the calf (m. Tibialis anterior and m. Gastrocnemius). The workload is adjustable up to 100 watt. The zero load is <5 watt at 25 rpm. The MR ergometer is an ergometer for use during MR studies. The MR ergometers workload is controlled with an electronical 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 wallfixation. The MR ergometer can be used for MR scanners up to 3 Tesla

Overview

Highlights

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.

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.

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.

Compatible with various MRIs at 1.5 and 3 Tesla

Compatible with
– Philips
– Siemens
– GE

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

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.

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

Philips MRI compatible

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

GE MRI compatible

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

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.

 

Up till 3 Tesla

Virtually no interference up till 3 Tesla through smart constructions and material use

Support

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.


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


Q - Can I use a RS232 to USB converter to connect an ergometer?
Yes you can. Make sure the chipset used in the converter is from FTDI to have good data acquisition. 
Not sure what this means? Contact us and we will help you to get the right converter.
