All these 3 multi-slice DICOM formats can be uploaded to Practique when creating single Resource representing the DICOM image. When uploading DICOM images to Practique users need to use ZIP compression (create ZIP file) in order to be able to upload a DICOM image. Please see the next section for descriptions of the ZIP file structure for each of the file types above.
Supported formats
You can find more information on what DICOM formats we support here
Image size: For optimum performance we recommend that DICOM images with a maximum of 100 slices be used. Images with more than 100 slices can cause significant slowing when downloading the exams onto local devices.
Total Exam Size: Practique supports a total exam size of 2GB. If you require larger exams than this please contact our service desk.

In this case Practique requires the user to create a flat ZIP file containing only the files with individual slices of one DICOM image. In the screenshot on the right the ZIP file structure would be the same as for multiple-file-multiple-slice. →

Exporting DICOM images from OsiriX
In this case Practique requires the user to create a hierarchical ZIP file containing only the files with individual slices of one DICOM image (See image below).
Practique supports import of ZIP files exported from OsiriX, provided that users use export settings detailed in this section. Because there are many versions of OsiriX software which may have different export capabilities, following information is only applicable to OsiriX 8.x.
...
Notice that the structure of the ZIP files depends if OsiriX is the same for all cases. When "Patient" had more DICOM associated and how many slices those DICOM images hadhas multiple DICOM images (series) in OsiriX resulting ZIP file will contain the same number of folders as there is series, for example LC203.
Uploading DICOM images to Practique
Once user has prepared ZIP files either manually as per “Preparing DICOM ZIP file” or using OsiriX as per “Exporting DICOM images from OsiriX” ZIP files can be uploaded to Practique to create Resources.
Keep in mind that in Practique one Resource corresponds to one DICOM image (can be multi-slice).
Users can use “+ Create new resource” when ZIP file they’re uploading contains single DICOM image (can be multiple slice).
When uploading ZIP file (most likely export from OsiriX) which contains multiple DICOM images (as for example LC203 mentioned above) user must use “+ Create multiple Resources” and Practique will create Resource for each DICOM image which is contained within the ZIP archive.
