Entities Definition

Study

Definition: A study is a collection of slides or annotations, in which users/pathologists examine and analyze WSI or ROI to make annotations and/or evaluations for a medical specialty. The studies could be assigned to multiple users/pathologists. The studies could be a hierarchical structure.

functionalities:

1. create a studies
2. read studies
3. update studies
4. delete studies
5. update the type of studies
6. update the specialty of studies
7. add slides
8. remove slides
9. add annotations
10. remove annotations
11. add users
12. remove users
13. move studies to (hierarchical structure)
14. search studies based on some conditionals

Only a study that has slides or annotations could be assigned to users/pathologies

Slide

Definition: a slide is a whole-slide image (also known as a virtual slide).

Support format:

• Aperio (.svs, .tif)

• Philips (.tiff)
• Sakura (.svslide)
• Trestle (.tif)
• Ventana (.bif, .tif)
• Generic tiled TIFF (.tif)

Schema:

functionalities:

1. upload a slide
2. upload a slide bundle
