Annotation Projects

Breast Lesion Annotation

1,102 images containing lesions were identified from 13,210 breast ultrasound scans. The lesions were then labeled as benign or malignant according to the biopsy results.

Pulmonary Nodule Annotation

Over 1,000 thoracic CT scans were examined for nodule identification. The nodule locations were marked, and their 3D boundaries were delineated.

Intracranial Hemorrhage Annotation

In this project, 2,816 head CT scans were classified according to hemorrhage subtypes (e.g., cerebral hemorrhage, intraventricular hemorrhage, subdural hemorrhage, and epidural hemorrhage). The cerebral regions and hemorrhage areas were delineated in each 2D slice.

Coronary Structure Annotation

Vessel walls were delineated and coronary artery 3D tree structure were reconstructed in over 20,000 coronary CT angiography images. Lumen boundaries were delineated and tracked from over 500 coronary DSA scans.
