Instrument User Guide Rev. 2.6 Cranial/ENT Optical Tracking
Non-clinical testing has demonstrated the Softouch is MR Conditional. It
can be safely used in the MR environment under the following conditions:
• MR environment with 1.5 or 3.0 Tesla scanner.
• To prevent autonomous acceleration, do not move Softouch across the
5 Gauss (0.5 mTesla) line.
• Softouch may only be used in an MR environment with a 5 Gauss (0.5
mTesla) line clearly indicated on the floor surrounding the MR scanner.
• Do not use or activate Softouch during an MRI examination.
MR-induced malfunction testing with device exposure to the clinical level
static field B , the time-varying gradient field (dB/dt) and the RF field (B1,
0
E) in 1.5 Tesla and 3.0 Tesla MR systems passed all tests according to
Brainlab testing procedure.
After use, always store Softouch in the provided storage case outside the
MR environment.
