Uploading your data

When the basic configuration of your reader study is ready, it is time to collect your data. Grand Challenge supports the following image formats: .mha, .mhd, .raw, .zraw, .dcm, .tiff, .png, .jpeg and .jpg. Besides images, it is also possible to use other objects in your reader study, such as regions of interest to guide your readers to certain areas in an image, or other values to provide default answers to the questions, see default answers. You do need at least one image per display set.

You can upload your data by using the menu on the left hand side of the screen: Side menu → Cases as shown below. The status of your image uploads can be found on this page.

Alternatively, you could use the Grand Challenge API Client to upload your data through Python.

Using display sets

Uploading images as described above creates a display set for each image, where each image is linked to interface Generic Medical Image. A single display set contains all the images needed for a case, where each image is defined by an interface. Within a display set the interface needs to be unique. If you would like more than one image in a single display set, you can do so by uploading images with a different interface. You can specify the desired interface for the images you upload:

Whenever you add an image with a new interface to a reader study, that interface will be added to all existing display sets in your reader study. You can batch upload all images for each of the interfaces you plan to use in your reader study. The Grand Challenge API Client also supports adding non-image type interfaces to your reader study.
