Medical Data Annotation Services
Build reliable training datasets for healthcare AI with expert medical data annotation. We annotate medical images, DICOM and NIfTI scans, clinical text, surgical videos and multimodal healthcare data using project-specific guidelines, secure workflows and rigorous quality control.


🧵 Medical annotation tailored to your use case
Precise medical annotations, adapted to your use cases, formats (DICOM, NifTI, HL7, etc.) and clinical requirements. Ideal for training your health AI models. In the healthcare sector, medical data labeling requires absolute accuracy to support accurate diagnosis and avoid misdiagnosis.
🥇 Medical domain expertise
Build a project team combining trained medical data annotators with relevant domain specialists. We support complex requirements involving anatomy, radiology, pathology, medical terminology and clinical documentation.
🧬 Annotate complexity
Neurosurgery, pathology, clinical reports: our experts know how to annotate rich and sensitive medical data, whether it is images, videos or specialized texts. Protect sensitive medical data through controlled access, confidentiality measures and appropriate anonymization requirements.
Medical Data Annotation for Healthcare

Bounding Boxes (or boundary boxes) in medical image annotation
In medical annotation, “Bounding Boxes” make it possible to precisely locate anatomical structures, anomalies or instruments on medical images, in order to prepare datasets to train AI models.
Identifying objects to be annotated
Precise framing of objects
Category labeling
Validating annotations
Radiology - Detection and location of tumors, nodules or fractures on images (MRI, CT, radiographs)
AI-assisted surgery - Real-time identification of surgical instruments in surgical videos
Digital pathology - Framing suspicious areas on scanned slides for histological analysis

Polygons
Polygons allow precise delineation of medical structures with irregular shapes — tumors, organs, lesions or bone structures — by following their exact outline on medical images (MRI, CT, etc.).
Identifying objects to be annotated
Precise framing of objects
Category labeling
Validating annotations
Annotation of bone structures (vertebrae, joints, fractures) for orthopedic or postural analysis
Precise delineation of tumors on MRIs or scanners, to measure their size and monitor their evolution
Organ segmentation (liver, lungs, heart, etc.) with complex contours, for training diagnostic models

Keypoints
Keypoints are used to mark specific positions on an object or body, such as joints, facial features, or anatomical landmarks. They allow a detailed analysis of shapes, movements or postures.
Identifying objects to be annotated
Precise framing of objects
Category labeling
Validating annotations
Body joint annotation for posture analysis, motion tracking, or detection of biomechanical abnormalities
Precise facial landmarking (eyes, nose, mouth) for facial recognition or emotion analysis
Dental keypoint annotation (crown, gum, root) for 3D modeling, orthodontic planning, or computer-assisted surgery

Free contours
Free contours allow complex shapes to be manually drawn directly onto an image, with great precision. This method is particularly useful for segmenting irregular structures.
Identifying objects to be annotated
Precise framing of objects
Category labeling
Validating annotations
Manual delineation of irregular tumors or lesions on MRI or CT scans for precise clinical monitoring
Fine segmentation of soft tissues or complex organs (brain, liver, lungs) with non-standard shapes
Detailed annotation of wounds, burns, or pathological skin areas in dermatological imaging

Polylines
Polylines are series of connected line segments used to accurately annotate linear or sinuous structures. In particular, they make it possible to follow blood vessels, nerves, or even to delimit complex areas within organs such as the lungs.
Identifying objects to be annotated
Precise framing of objects
Category labeling
Validating annotations
Precise annotation of vascular networks (arteries, veins, capillaries) on angiographic images for blood flow analysis
Tracing of nerves or muscle fibers in MRI scans for neurological or surgical studies
Delineation of branched structures in lungs or bronchi for respiratory anomaly detection

3D Volumes
3D volumes (“3D Volumes”) allow structures to be annotated in volumetric data such as MRIs or scanners, taking into account depth and different sections.
Identifying objects to be annotated
Precise framing of objects
Category labeling
Validating annotations
3D segmentation of brain tumors on MRI scans for surgical planning or radiotherapy preparation
Volumetric reconstruction of the heart or lungs from CT scans for functional and morphological analysis
3D annotation of internal organs (liver, kidneys, pancreas) to create anatomical models for medical AI training
