Requirements

• Registration: Registered radiologist in your country of practice with active license • Experience: 3–10 years' experience in radiology, with a chest/thoracic focus • Knowledge: Strong grounding in thoracic anatomy and cross-sectional CT. • Attention to detail: Proven accuracy and consistency in image review or measurement work. • Technical proficiency: Comfortable using structured annotation tools and digital platforms. • Prior imaging annotation experience is an advantage but not required. • Language: Native or near-native written English. • You will have the right to work in your country of residence. • You will work as an independent contractor.

Responsibilities

• Click-point placement: Mark specific coordinates on a scan, such as the centre of a nodule. • Bounding boxes: Draw boxes around defined regions of interest, such as a flagged lesion. • Simple measurements: Record diameter, or distance between two marked points, on segmentations or polygons already drawn. • Guideline application: Work to an annotation guideline covering placement conventions, boundary definitions and measurement rules, applied consistently across a large volume of studies. • Edge case handling: Flag ambiguous cases with a short rationale so guidance can be refined. • This is structural markup project with no interpretation required. You will not be reading scans for diagnosis, judging malignancy, or making clinical decisions.

Benefits
