Stepwise processing is started by selecting the Maximum Probability Atlas tab.
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.
The aim of the averaging is to generate an image which resembles as good as possible to the PET template used for the spatial normalization. To continue please select the None radio button activate the action button in the lower right which has changed to Norm.
