EASY6MRI is a complete redesign of our widely used Electromagnetic (EM) Exposure Acquisition System EASY4MRI: it is smaller, more cost-efficient, and directly connects our classic specific absorption rate (SAR) and field probes via an optical link (DAEasy6 + EASY6RU) to the computer. The user-friendly EASY6 software allows the acquisition of data from 1–10 probes while each measurement channel is individually characterized and processed. It further enables high precision measurements of the EM near and far field to be collected and stored from low MHz to 10 GHz with high spatial resolution. Like its predecessor, EASY6MRI is designed to work within hostile EM environments, including Magnetic Resonance Imaging (MRI) scanners up to 7 Tesla.
Preliminary specifications of the EASY6MRI system are as listed below:
Field Measurement Capability
|E-field||frequency range: 20 - 6000 MHz
dynamic range: 2 - 1000 V/m
directivity: < ±0.3 dB
|H-field||frequency range: 20 - 3000 MHz
dynamic range: 0.01 - 5 A/m at 128 MHz
directivity: < ±0.2 dB
|SAR||frequency range: 10 - 6000 MHz
dynamic range: 10 µW/g - 100 W/kg
directivity: < ±0.3 dB
|Temp||dynamic range: 0°C - 60°C
noise: < 2 mK (sampling time: 0.1s)
spatial resolution: 1 mm
|Sampling Rate||< ms - hours|
EASY6MRI can be used in hostile EMF environments.
Examples from MRI applications include:
MRI compliance testing; Assessment of occupational exposure to EMF around MRI equipment; SAR evaluation of implantable medical devices; any high precision EMF measurements in reverberation chambers, anechoic chambers, open test sites, clinical environments or EMC laboratories
|Phantom||ASTM2009 and ELIT1.5/3.0 Phantoms for compliance testing of implants within MRI Environments. See ZMT Zurich MedTech AG for more information.
|Working Modes||Field strength meter (display of values, min, max and statistics)
Scope meter (field components or total values vs. time)
Separate process with individual parameters for each channel
|Minimum Requirements||One DAEasy6 and one field or temperature probe (not included)|
Two options of the system are available, single EASY6MRI for 1 single probe measurements, and extended EASY6MRI for up to 10 probes measurement.
|Remarks||The computer or touch interface connected to EASY6MRI cannot be operated in the close vicinity of the scanner.|
