About the role

  • We're looking for Sonographers, Ultrasound Technologists, and other medical imaging professionals with hands-on ultrasound experience to support an AI-powered medical imaging project.
  • As an Ultrasound Image Annotator, you will review ultrasound video frames and accurately identify and label anatomical structures and acoustic shadows. Your work will contribute to the development of high-quality datasets used to train and improve AI-powered medical imaging technologies.
  • This role is ideal for professionals who have experience interpreting ultrasound images, enjoy detail-oriented work, and can consistently follow precise guidelines.

Previous data annotation experience is not required. Training on the annotation tool and project-specific guidelines will be provided.

What you'll do

  • Review ultrasound video frames to identify anatomical structures, tissue boundaries, and acoustic shadows.
  • Accurately outline and label structures using specialized annotation software and detailed guidelines.
  • Compare images across video frames and reference materials to ensure accurate and consistent labeling.
  • Identify and flag unclear or low-quality images rather than making assumptions.
  • Maintain high standards of accuracy, consistency, and productivity, incorporating feedback to continuously improve.
  • Participate in training, calibration sessions, and occasional team discussions.

Requirements

  • Hands-on experience working with and interpreting ultrasound images, ideally as a Sonographer, Ultrasound Technologist, or related medical imaging professional.
  • Working knowledge of anatomy, particularly bone, organ, and skeletal structures, including how these appear on ultrasound.
  • Understanding of ultrasound image characteristics, including brightness, depth, tissue boundaries, and acoustic shadowing.
  • Strong attention to detail and the ability to follow precise written instructions consistently.
  • Comfort using computers and learning new software, including tools requiring accurate mouse or stylus control.
  • Professional proficiency in English, both written and spoken.
  • Ability to work independently, maintain confidentiality, and participate in scheduled training and calibration sessions.

Nice to have

  • Certification or formal training in sonography, radiography, or a related medical imaging field.
  • Experience in musculoskeletal, spine, organ, or pain management ultrasound imaging.
  • Previous experience in medical image annotation, data labeling, or image quality review.
  • Experience working with detailed imaging protocols, reference images, or standardized guidelines.
