Medical Imaging Annotation for AI-Assisted Diagnostic System (ECG & MRI)
Led the annotation and quality review of a 15,000+ sample medical imaging dataset comprising ECG signal plots and MRI scans for a clinical AI diagnostic research project at the University College Hospital, Ibadan. Responsibilities included pixel-level segmentation of anatomical structures in MRI images, classification of ECG rhythms into diagnostic categories (normal sinus, atrial fibrillation, ventricular tachycardia, etc.), and evaluation/rating of model predictions against ground-truth clinical labels. Applied DICOM-aware annotation workflows using Label Studio and CVAT, ensuring HIPAA-compliant data handling and strict inter-annotator agreement protocols. Achieved a >98% agreement score across the annotation team and contributed labeled data that directly supported a peer-reviewed publication on AI-assisted cardiac diagnostics.
