Ultrasound Image Annotator (Sonographer / Ultrasound Technologist) at CloudFactory

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.
