____________________________________________________________________________________________

Functionality is available in a separate module which is activated in the Pro edition for an extra fee
____________________________________________________________________________________________

The DICOM Viewer provides for an opportunity to save the annotation results in a JSON ﬁle, as well as to open ﬁles with annotation results in order to resume work. When a ﬁle is opened, the data contained in it are added to the data that already exist.

12.6.1 Saving Annotation Results

To save the image annotation results, click the Save results button on the image annotation panel. In the dialog box that pops up, choose the directory where the ﬁle with the annotation results is to be saved and print the name of the ﬁle. Click Save to save the ﬁle or Cancel to cancel.

The results are saved in a JSON ﬁle containing the following information:

data on groups and classes;

data on images (study ID, series ID, image ID);

data on objects of the contours.

The saved ﬁle contains information on all the objects annotated for all the study series in the current tab (for all series from the series panel of the current tab). The ﬁle is saved without DICOM data.

12.6.2 Opening Annotation Results

To open the image annotation results that were saved earlier, select the Open image annotation results... option on the File menu. In the dialog box that pops up, select a saved JSON ﬁle with annotation results.

The following conditions must be met in order to open the annotation results successfully:

the uid of the tree of groups and classes in the JSON ﬁle must be the same as the uid of the tree of groups and classes opened in the program;

the version of the tree of groups and classes in the JSON ﬁle must be inferior to or the same as the version of the tree of groups and classes opened in the program;

in the local DICOM Viewer storage, there must be at least one series speciﬁed in the JSON ﬁle.

If at least one of these conditions is not met, a dialog box notifying of the error will pop up and the annotation results will not be opened.

If the version of the tree of groups and classes in the JSON ﬁle is superior to the version of the tree opened in the program, a respective tree replacement notiﬁcation will pop up when the user attempts to open the annotation results.

If some of the series speciﬁed in the JSON ﬁle are missing from the local storage, a respective notiﬁcation will pop up when the user attempts to open the annotation results.
