+The **ARCADE Combined Dataset** is a curated collection of coronary angiography images and annotations designed to evaluate coronary artery stenosis. This version has been processed and exported using [FiftyOne](https://voxel51.com/fiftyone), and includes cleaned segmentation data, metadata fields for clinical context, and embedded visual labels.

-
-#### Who are the source data producers?
+- `segmentations`: COCO-style detection masks per coronary artery segment.
+- `phase`: The acquisition phase of the angiography video.
+- `task`: A specific labeling task (segmentation or regression) is used.
+- `subset_name`: Subdivision info (train, val, test).
+- `coco_id`: Corresponding COCO ID for alignment with original sources.
+- `filepath`: Path to the image file.
+- `metadata`: Image metadata including dimensions and pixel spacing.
 
-<!-- This section describes the people or systems who originally created the data. It should also include self-reported demographic or identity information for the source data creators if this information is available. -->
+## Format
 
-[More Information Needed]
+This dataset is stored in **FiftyOneDataset format**, which consists of:
+- `data.json`: Metadata and label references
+- `data/`: Folder containing all image samples
+- Optional: auxiliary files (e.g., `README.md`, config, JSON index)
