Healthcare and medical annotation
Clinician-led annotation, expert review and ground truth for medical AI, across diagnostic imaging, digital pathology, surgical video and clinical text.

Who it is for
Radiology and pathology AI teams, clinical AI groups, pharma and real-world-evidence programmes, and platforms that need clinician ground truth they can rely on for training and evaluation.
Clinician-led annotation
We work with medical professionals in the UK and a large pool in Bangladesh for expert labelling, review and ground truth. Clinical expertise is applied where the task needs specialist judgement, and the work is reviewed before delivery.
Radiology and diagnostic imaging
Clinician-reviewed annotation of CT, MRI, X-ray, ultrasound and related diagnostic images, from region outlines and segmentation to findings and classification, using our Computer Vision method.
Digital pathology
Whole-slide annotation, cell and tissue segmentation, and biomarker scoring, carried out to the scoring rules your programme specifies.
Wider imaging and video
Endoscopy and surgical or operating-room video, including actions, phases and instruments, labelled frame by frame or as timestamped segments.
Clinical text
Annotation and expert review of clinical notes, reports and similar text, such as extracting findings or classifying documents, building on our Natural Language Processing services.
Patient-data workflows
Structuring, review and de-identification of patient-related data, carried out under the handling practices agreed for each project and described on Security and Compliance. See also Other Data Services.
Clinical AI and expert review
Physician review of events, diagnoses, severity and model-safety judgements: expert assessment of where a clinical model's outputs are right, wrong or unsafe.
Pharma and real-world evidence
Expert-labelled imaging and pathology datasets for drug development and biomarker work.
Existing proof
Our published neuron and axon project is one example of biomedical-research annotation. See the full neuron and axon story.
Delivery, security and quote
Every project follows How We Work. Sensitive data is handled only under the practices agreed in writing for your project; see Security and Compliance for what those cover.
