System Overview
Teslameter
To ensure that the Fabius MRI works safely and
without interference in the proximity of an MRT sys-
tem, and that the MRT’s imaging is not influenced
out of margin, there is defined distance that the
Fabius MRI machine must maintain from the MRT
system. For exposition in a homogenous magnetic
field, there is a limit of 40 mtesla (400 gauss) to be
kept for the Fabius MRI.
The Fabius MRI is a floor-based workstation that
can be moved around the room as required by the
patient’s respiration/anesthesia during the MRT
treatment. If the fringe field strenght is exceeded,
an acoustic signal is annunciated and continues to
annunciate until the Fabius MRI is repositioned to
the required limit of 40 mtesla (400 gauss). The
array for detecting the magnetic field is a position-
ing aid towards the MRT magnet.
Location of the Sensors
There are two sensors (one on each side) located
in the lower part of basic unit (
1) .
Checking the sensors in self-test mode, e.g., after
switching on the machine, is not necessary. Both
Tesla sensors are constantly active when the
Fabius MRI main power switch is turned on, includ-
ing in Standby mode and operation on battery
power.
