8.8.2. Thermal Sequence Prescription on the MRI
CAUTION: MR Thermometry Data. The MR data must use the NeuroBlate System
defined sequence parameters for temperature measurement. This includes use of a
specific GRE sequence preinstalled on the target MRI system. The only modifications
allowed are position, orientation and phase encode direction depending on the location.
Failure conditions will result if parameters are changed or the position/orientation is not
aligned with the required treatment planes. If in-plane panning is required, the FOV
must include the treatment areas. Careful attention must be made so that in plane
panning is done correctly and the resulting acquisition plane is still aligned with the
prescribed treatment planes. FOV position adjustment (in plane panning) can only be
made for the first treatment slice. Thereafter, the software shall lock onto the 4 corner
positions of the images and only allow images along the probe trajectory aligned to
these.
