Is the image formed by an x-ray shot a semi-structured data?

No. Doctors' handwritten medical records and x-ray images are unstructured data that must be processed twice to form structured data, and x-ray images are not a kind of semi-structured data. Structured data include: clinical business data (HIS, EMR, LIS), operation management data (HRP, finance, drugs, materials), logistics management data (equipment, hospital construction, water, electricity, coal, bedding), etc. Semi-structured data: ECG data, EEG data, hearing data, etc. Unstructured data: medical images (CT, MRI, X-ray), medical pictures (rhinoscopy, laryngoscopy, pathology), history of medical cases (JPG, PDF), history of medical records (PDF, TXT), etc.
