Data is transferred from the HFA3 to PeriData using a FILE. The HFA3 exports the file to a special folder. PeriData reads the file from this folder and then deletes it. There are 2 important details to note:
The HFA3 is able to export different types (formats) of DICOM files. All of them have the file extension .dcm, but differ internally. The difference is only noted when the file is read/opened. Only the format DICOM-OPV contains utilisable visual field data and is suitable for PeriData.
Non-fitting DICOM formats: DICOM-EPDF (embedded PDF) is a PDF wrapped into a DICOM container. HFA3 Format is a proprietory Zeiss format. If PeriData finds a not-fitting DICOM file in the import folder, it will give a notification "wrong SOP class" and deletes the file
The exchange folder is best created directly on the HFA3. The folder is shared on the network. The HFA exports (writes) the DICOM OPV files to this folder. For technical reasons, the directory must be mapped for this purpose. The PC in the perimeter room reads the files and deletes them.
Pitfall: In the field "Report Export Location" where you select the mapped drive, it is also possible to declare a UNC path as target folder. But the DICOM OPV file is not exported.
