extra_gated_heading: Access to GazeSearch requires MIMIC-CXR credentials
extra_gated_description: >
  GazeSearch includes chest X-ray images derived from **MIMIC-CXR**, which is
  distributed under the *PhysioNet Credentialed Health Data Use Agreement*. To
  be granted access to this dataset you must already be credentialed for
  MIMIC-CXR on PhysioNet and agree to use the data only for the purposes
  permitted by that agreement.

  Requests are reviewed manually. Please provide accurate information — false
  declarations will result in revoked access.
extra_gated_prompt: >
  By requesting access I confirm that I will use GazeSearch only for research
  that complies with the PhysioNet Credentialed Health Data Use Agreement for
  MIMIC-CXR and will not redistribute the images.

GazeSearch: Radiology Findings Search Benchmark (WACV 2025)

Access is gated. This dataset contains images derived from MIMIC-CXR and is only shared with users credentialed under the PhysioNet Credentialed Health Data Use Agreement. Click Request access at the top of the page and confirm you hold an active MIMIC-CXR credentialed-access account; requests without proof of authorization will be denied.

GazeSearch is a curated visual search dataset for evaluating search algorithms on radiology findings. It is built from medical eye-tracking data (REFLACX and EGD) paired with chest X-ray images from MIMIC-CXR, and captures how radiologists visually search for specific findings.

Annotation format

The JSON file is a list of scanpath samples (4,875 entries over 2,328 unique images). Each entry has:

Field	Description
name	Image filename in images/
subject	Radiologist / subject ID
task	Target finding being searched (e.g. lung opacity, cardiomegaly, ...)
condition	Presence of the finding (present)
bbox	Ground-truth bounding box [x, y, w, h] of the finding
X, Y	Fixation coordinates (in the 224×224 patch space)
T	Fixation durations (seconds)
length	Number of fixations (max 6; add a center fixation to get length-7 paper setup)
fixOnTarget	Whether the scanpath ends on the target region
correct	Whether the radiologist's decision was correct
split	One of train (3,870) / valid (517) / test (488)

Tasks / findings

lung opacity, support devices, cardiomegaly, pleural effusion, atelectasis, edema, consolidation, enlarged cardiomediastinum, lung lesion, fracture, pneumonia, pneumothorax, pleural other.

Checkpoints

checkpoints/ckp_29999.pt is the trained ChestSearch scanpath-prediction baseline from the paper. M2F_R50.pkl and M2F_R50_MSDeformAttnPixelDecoder.pkl are the Mask2Former ResNet-50 backbone / pixel-decoder weights used to initialize training.

See the original repo for training/inference code and the src/demo_medical.ipynb demo notebook.
