A series can contain multiple cases, and a case can cover part or all of a series. | | Series Index (if applicable) | Unique identifier for the content as part of its series (e.g. image frames). | | Patch (if applicable) | Area of interest on an image to be annotated for the case, in WKT format with coordinates rescaled to a 0-100 scale. | | Study UID (if applicable) | Unique ID of the DICOM study that the annotated image was from. | | Series UID (if applicable) | Unique ID of the series within the DICOM study that the annotated image was from. | | Instance UID (if applicable) | Unique ID of the image within the DICOM series that was annotated. | **Reads and Annotations**

Term	Definition
Qualified Reads	Number of reads (“opinions”) on the case. Qualified Reads are those which meet a predefined accuracy criterion.
Correct Label	If Gold Standard case, the label, as assigned by you and/or an admin. If Labeled case, the Majority Label when the case has met a predefined consensus criterion. Cuboids are described using a standard WKT of the cross-section, followed by the DICOM study, series, and instance UIDs of the start and end slice: (cross_section_wkt, (start DICOM instance UIDs), (end DICOM instance UIDs)). The format is: (cross_section_wkt, DICOM UIDs of start slice, DICOM UIDs of end slice), where each set of UIDs is (study UID, series UID, instance UID)
Majority Label	Annotation in derived from Qualified Reads. The format is: (cross_section_wkt, DICOM UIDs of start slice, DICOM UIDs of end slice), where each set of UIDs is (study UID, series UID, instance UID)
Top Reads	Qualified Reads used to create the Majority Label.

**Measures of Confidence** | Term | Definition | | :--------- | :----------------------------------------------------------------------------------------------- | | Difficulty | [1 - average IoU] (Intersection over Union) between each of the Top Reads and the Correct Label. | | Agreement | Average IoU (Intersection over Union) between each of the Top Reads and the Majority Label. | **Other Information** | Term | Definition | | :-------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------- | | Internal Notes | Any notes internal to your team or tracked by Centaur relevant to the case. | | Comments | Comments on the case by our labelers. | | Flags | Flags on the case by our labelers. | | Explanation | Notes written by you and/or an admin to help train and educate labelers. The explanation is shown to labelers after they have submitted a read. | | Pre-answer explainers | Additional text information provided to labelers about a case prior to viewing. | | Static Highlight | Range and entity highlighted for any static highlights present on the case (e.g., [\{'range':[6,15], 'text': "this cell"}]). | # Reads CSV | Term | Definition | | :---------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Case ID | Unique identifier for cases in our system. | | User ID | Unique identifier for users in our system. | | Read ID | Unique identifier for reads in our system | | Qscore | The trailing average accuracy for the user when they submitted an answer to the associated case ID.
