Philips MRI
Philips MRI Entry Note: For Philips position and orientation entry, the
base plane is also needed for entry on Philips MRI. This is given by the
slice orientation label (e.g. CORONAL shown above by yellow box).
Entering orientation values on Philips requires the following steps in this
order to ensure final entry is correct:
1. Enter the required slice orientation (coronal/ sagittal/ transverse)
2. Enter zero for all angles (AP, RL, FH) to reset entry
3. Enter prescribed angles in the following order: First enter AP
angle, then RL and finally FH angle.
MR Image Guidance Note: Although probe insertion can be monitored on the MR console,
appropriate images can be sent to the software to load into the views in order to compare the
probe artifact evident during insertion with expected final probe linear position rendered in the
software. The measurement tool is useful to quantify the progress of insertion.
Probe Depth: If the actual probe depth position within the tissue as shown by the image
artifact is deemed to be at an ideal location but it does not align with software rendered probe,
adjust the depth position.
MR Image Loading:
Fast Spin Echo sequences are optimal for minimal probe artifact distortion and, if possible, with
the frequency encode direction opposite of parallel (anti-parallel) to the probe. These type of
scans used to evaluate the probe position within the tissue should be executed on the MRI only
when linear or rotary probe motion is NOT active.
For Siemens MRI:
Ensure all treatment day imaging has Distortion Correction enabled in 2D mode. This protocol
factor resides in the
Resolution
section under the
Filter
tab.
