OVERVIEW

EASY6

EASY6 is a complete redesign of our widely used Electromagnetic (EM) Exposure Acquisition System EASY4MRI. EASY6 is smaller, more cost-efficient, and connects up to 16 of our classic probes including E- and H-Field, dosimetric, and temperature probes via an optical link (EASY6-DAE + EASY6-EoF + EASY6-RU) to the computer. EASY6 is designed to operate anywhere, including MRI and EM hostile environments.

spatial resolution: 1 mm
Sampling Rate < ms - hours
Applications

Examples of general applications include:

  • Measurements in hostile EMF environments.
  • Free-space fields, dosimetry, and temperature evaluation.
  • Short and long-time high precision field monitoring.
  • High precision EMF measurements in reverberation chambers, anechoic chambers, open test sites, clinical environments or EMC laboratories
  • Validation of simulation results (e.g. Sim4Life).

Examples of MRI applications include: 

  • MRI compliance testing;
  • Assessment of occupational exposure to EMF around MRI equipment;
  • SAR and temperature evaluations of implantable medical devices.
Working Modes

Different modes can be selected: 

  • Field strength meter (display of values, min, max, and statistics)
  • Scope meter (field components or total values vs. time)
  • Support of up to 16 channels
  • Separate processes with individual parameters for each channel
Minimum Requirements One EASY6-DAE and one field or temperature probe (not included)
System

The system consists of an EASY6-DAE connected via an optical link EASY6-EoF to EASY6-RU offering a USB-link to any desktop/laptop computer. Two options of the system are available, EASY6-1 with one DAE (for single probe measurements), and EASY6-2 with two DAE (for 2 probe measurements).

Remarks The computer or touch interface connected to EASY6 cannot be operated in the close vicinity of the scanner.
