Sending VOI TACs to PKIN
The PXMOD tool is not aimed at interactive modeling. However, if the PKIN tool has been licensed, the PXMOD blood and TAC data can be easily transferred to PKIN by the 
button in the taskbar. A dialog will be opened, showing the available data.
Use a Send to to Kinetic Modeling button to copy the selected PXMOD information to PKIN. There are two variants available: the [SET] variant will overwrite the existing data in PKIN without asking for a confirmation, while the [ADD] variant will first create a new PKIN workspace. If PKIN is not yet running, it is started and loaded with the selected data. In PKIN, interactive modeling can be performed using all methods, and the information gained can be useful for improving the configuration of the PXMOD model.
Sending pixelwise TACs to PKIN
In addition to using the VOI TACs it is also possible to send pixelwise TACs to PKIN. To this end configure in the first row of the Map Comparison page the dynamic input data, open and extend the data inspector window so that the pixelwise TAC is shown when clicking at an image pixel.
Note the Append checkbox. If enabled, a pixelwise TAC is added to the curve area whenever clicking into the image. The box Data with slice-wise timing is applicable for data acquired if the file-of-view of the scanner is moving during the acquisition. In this case, the timing of the slices may vary along the z-axis and will be used when displaying the curves.
Use a Send curve(s) to PKIN button to transfer the curves to PKIN, either to the currently open workspace, or to a new one. Add curve(s) to existing list in PKIN is needed to append the curves to the current workspace rather than overwriting the existing content.
