# DualXrayBench

DualXrayBench is the 1,594-example, eight-task evaluation split accompanying the GSR work on dual-view X-ray reasoning. Each record pairs a top-view and side-view image with one multiple-choice question, its reference answer, task metadata, and reference target-instance boxes.

## Files

- `annotations/benchmark.jsonl`: stable public records with `task_id`, `task_name`, and relative top/side image paths.
- `annotations/dual-xray-benchmark.json`: unchanged paper-v1 canonical compatibility file.
- `annotations/tasks/*.jsonl`: the same stable records partitioned by task.
- `images/top` and `images/side`: exactly 1,594 paired JPEG images in each view.
- `tasks.json`, `schema.json`, and `evaluation_protocol.md`: task definitions, record schema, and scoring guidance.

The record order is the frozen canonical paper-v1 order. Image paths are relative to this repository. The benchmark image IDs have zero overlap with the GSXray training image IDs used for this release.

## Loading

```python
import json

with open("annotations/benchmark.jsonl", encoding="utf-8") as handle:
    records = [json.loads(line) for line in handle]

first = records[0]
print(first["images"]["top"], first["images"]["side"], first["task_id"])
```

See `evaluation_protocol.md` before reporting results. Do not train or tune on benchmark answers.
