Define your archive items

After you have created your archive, it is time to add data to it and set up your archive items. An archive item is a collection of images, files or metadata that together make up one case in your archive. In the simplest case, an archive item consists of just one medical image, but they can contain any combination of data you can think of. For images, you can choose from the following formats: .mha, .mhd, .raw, .zraw, .dcm, .tiff, .png, .jpeg and .jpg. Next to images, we support .json files for metadata and annotations, and a number of other file formats, including .obj and .mp4 files. Each file or value you attach to an archive item needs to be associated with a unique interface.

You can upload your data by using the menu on the left hand side of the screen: **Side menu → Items**. You have two options: batch uploading images or creating each archive item separately, one by one.

Batch uploading images¶

Uploading images in batch creates one archive item for each image in the batch with the interface chosen by you on the upload form. In the example below, 2 archive items will be created, with each item containing a CT image.

The overview table will then look as follows:

You can monitor the status of your uploads on this page.

Archive items with more than 1 image or other data types¶

If you wanted to add a secondary image or another object to each archive item, you can do so by clicking on the edit icon for each case and then choose "Add value for new interface". Type the interface you would like to add, for example "Airway segmentation", upload the secondary image and click "save".

Note that you could also batch upload the secondary images with the respective interface. Doing so however, will create a new archive item for each secondary image, leaving you with double the amount of archive items as before. To get them organized properly, you will still need to edit each item separately and ultimately delete any leftover, duplicate items. So batch uploading the secondary images leaves you with more work ultimately.

Instead of bulk uploading and then editing, you could of course also create the archive items one by one. To do so, just choose "Add Archive Item (single)" on the items overview page.

Finally, if you have a lot of items to define, you might be best advised to use our API client and create the archive items programmatically. Read more about that here.

Good to know¶

• Images can be used in more than one case.
• You can inspect your archive items one by one in a web viewer by clicking on the “view” icon. Note that the web viewer does not support all file formats and is optimized for image and annotation viewing.
• You can also download all images by clicking on Export in the sidebar.
• When you edit an archive item to, for example, replace a file with a new file, note that this will delete the original file. The old value will be gone after editing, so beware of updating the values of your items.
