Update, December 12, 2016: EMAREI LED flashlight SLT-MRI 220 Lumen passed praxis test in a 7,7 Tesla Magnetat Tesla Engineering, UK. Steve Bates, CEO of Tesla confirmed "We tried your torch from the kit (EAI0563) yesterday at 7,7T Magnet. Thumbs up! Week 1/2017 we will try the 9 T Magnet."
June 30, 2016 Result of EMAREI flashlight Test:
Low-Magnetic EMAREI Flashlight incl. 3 low-magnetic batteries
conducted on June 14, 2016 in CHRU Nancy Hôpital Central, France
with a GE Healthcare, Discovery MR750w 3.0T
A low-Magnetic Flashlight EAI0144 consisting of body parts and low magnetic batteries, is considered as “MR Conditional” in accordance with the definition of the ASTM F2503-13 standard. The results of in vitro tests have demonstrated that the Flashlight does not present any danger in the following examination conditions:
PRECAUTIONS OF USE
The respect of MR conditions guarantee security of the use of Low-Magnetic Flashlight EAI0144 in MR environment. Caution, near the tunnel entrance the users can feel some forces which disturb the manipulation of the Flashlight. For an optimal use EMAREI recommend not to approach the Flashlight over one meter the tunnel entrance.
MRI TESTING METHOD:
The assessment of the torque induced by a magnetic field has been conducted in accordance with ASTM F2213 standard. It was showed that the torque induced by a magnetic field of 3-Tesla or less does not present any risks.
The tests conducted in accordance with ASTM F2052 standard showed that the displacement force induced by a spatial gradient of the static magnetic field limited to 5.26 T/m did not present any risks.
