Medical Image Annotator (Medical Imaging)

The work

You will annotate de-identified CT and MRI scans for an AI training dataset. The work focuses on outlining anatomical structures and findings, including organs, lesions, and other specified structures, slice by slice.

You will follow a project annotation protocol, create and export segmentation masks, flag unclear or poor-quality scans, and revise your work after quality-check feedback.

• Contour specified organs, lesions, or structures on CT and MRI scans.
• Label images consistently using the project annotation protocol.
• Create and export segmentation masks with annotation software.
• Flag poor-quality, ambiguous, or unusual scans for review.
• Revise annotations based on quality-check feedback.
• Meet agreed weekly case targets and deadlines.

What it pays and takes

This is a remote, part-time freelance contract role for experienced medical imaging contributors. The project requires strong cross-sectional anatomy skills and careful, consistent work.

• Pay: $10 to $50 per hour.
• Time: Less than 20 hours per week, with flexible hours.
• Location: Open to candidates worldwide; the work is fully remote.
• Language: Professional fluency in English.
• Experience: Expert-level experience in medical imaging annotation or a related field.
• Background: Radiology, medical imaging, radiography, medical imaging technology, radiation therapy, or radiotherapy.
• Skills: Good cross-sectional anatomy knowledge and attention to detail.

About AI training work

AI training work uses examples prepared and reviewed by people to help artificial intelligence systems learn. Medical imaging specialists are needed because accurate anatomy and scan interpretation require knowledge that general annotators may not have.
