Pet-Ct Viewer

After choosing a valid Pet-Ct study in the Opening dialog, an image like the following will appear (see demo and 2nd demo)

Initially the MIP (Maximum Intensity Projection) image will be rotating to give an overall feeling of the data. It is rotating when the >> button is pressed. In order to choose a point on the MIP, it is customary to first press F or S to stop it in the Front or Side view.

This is a brain study where a point has been chosen in the MIP image by clicking on the point. A green cross will appear on the point in all images. It has automatically chosen the correct axial slice in both the PET and CT stacks and the position of the chosen point is indicated by the green cross on these images. The SUV (Standard Uptake Value) of the area in the PET image is displayed, along with the Housenfeld value in the CT image.

The green cross and the SUV and CT values remain so long as the cursor remains in the vicinity of the chosen point. When it is moved away, both disappear so as not to cover up the data itself. If you are interested in the SUV of any point on the PET or the CT value of any point, simply click on the appropriate point. Green crosses will appear on all 3 images showing the relative positions and values. Again they will remain while the cursor remains in the vicinity of the chosen point.

In order to see the fusion image, click on the MIP button in order to release it. The MIP image will be replaced by the fusion image. Alternatively, you may right click the Pet image and a pop up menu will appear allowing you to display the fused image in place of the Pet image.
