The easiest way to start stepwise processing is to select the Brain Parcellation tab.
PET Image Loading
The Load PET button for loading the PET images is located in the right control area. As usual it is an option button which needs to be set to the appropriate data format with the indicated arrow. For loading images which are not saved in a PMOD database it is recommended to use the Autodetect format. Note that the PET series may be static or dynamic.
In the case of a dynamic PET series, a new series is generated by averaging a range of frames and assigned to the PET AVG tab. The averaging range can be defined by the From and To number fields, or dragging the range indicators in the Aver bar. After any modification of the range, the average is recalculated and the display updated.
The original and the averaged images are shown in a fusion rendering which can be controlled in the area below the controls of the individual images.
PET Image Cropping
If the PET field-of-view is much larger than the brain, the data set should be reduced in order to save RAM and optimize processing. In this case, enable the Crop box and place the yellow crop volume indication by clicking at the brain center so that the brain is fully enclosed. The edge size in [mm] can be adjusted for each direction by selecting the size in the corresponding list. The PET Image button initiates cropping, whereby the original data are replaced. If cropping is not initiated manually, a request will be shown when proceeding to the next step. Note: The cropping operation is only allowed once.
To continue with loading the MR images please select the MR action button in the lower right.
