NeuroQ™ PET-FDG Processing
4 steps to accurate processing - everytime.
Quality Control Module
NeuroQ™ will initially open to the Quality Control Page.
It is recommended that this procedure is followed for every PET-FDG study.
Step 1 - Set Axial Plane Limits
This feature allows the user to set the upper and lower limits for reconstruction by clicking the up and down arrows to move the lines. The limits can also be set by moving the cursor to a point on the image and click left to set the limit (Left Image).
The limits should be set so that only the brain images are included in the reconstruction.
When the limits are set to the proper location check the Accept box (Right Image).
Step 2 - Removal of Scalp Activity
This feature allows for the removal of the scalp activity around the brain. In some cases there is excessive scalp activity which can interfere with the reformatting of the patients study to match the normal template. Move the slider bar to the desired threshold (20% is recommended) and then click on the Process button.
The processed images are shown in the bottom row (right image). Triangulation is enabled on these images by clicking left on any image and it will show you the plane for that location on the other two images.
When the images are processed for scalp correction, the Accept box will be checked.
If not enough or too much scalp activty has been removed, uncheck the Accept box and change the threshold appropriately and reprocess.
Step 3 - Rigid Registration
Rigid Registration aligns the patients brain with the reference volume using only translations and rotations prior to the Reformatting process.
This additional registration is helpful in cases where the patients head has excessive tilt.
It is recommended that Rigid Registration button be selected for all studies prior to reformatting.
The top row shows the normal template as the reference image the middle row are the patients images and the bottom row are the fused reference and patient images after realignment. Triangulation is enabled on these images by clicking left on any image and it will show you the plane for that location on the other two images.
When the images are processed the Accept check box will be checked.
Step 4 - Reformat PET-FDG with 10 Iterations
If all of these QC steps above are performed, then select the Reformat PET button. Reformatting will be performed with 10 iterations. Click OK in the next message to reformat.
The study will take a few moments to reformat.
Finally, the study, reformatted with 10 iterations as noted under the third image in the top box labeled "Reformated Patient Brain (Iterations 10)" will be ready for reading.
