Medical Data Annotation
Medical Data Annotation现状Analysis
Data孤岛
HIS、PACS等重要Data难以互通共享。
difficult to realize value
Data价值Achieve面临重重困境。
合规风险
DataDue to its high sensitivity，Prone to compliance violations during sharing and trading。
3D Data Complexity
Medical Imaging AnnotationMulti-planar processing requiredReconstruction（MPR）Data，Traditional tools produce layer stacking errors in 3D slice annotation。

How we solve these challenges for you
01
Data Collection & De-identification
MedicalData Source包括电子Medical Record、MedicalImaging（CT/MRI/X光）、Clinical研究Data等，需Coverage不同yr龄segment、Disease阶segment及Medical InstitutionType。De-identification required after collection，移除Patient姓名、身recordsCertificate numbers and direct identifiers，And sensitive information such as rare diseasesVirtualizedProcessing。
02
Data Preprocessing & Standardization
Raw Data需进row清洗（去除Duplicate内容、纠正Medical Record错别字、剔除模糊Imaging）和Format转换（统一Imagingmin辨率、SpecMedical TerminologyTable述）。E.g., harmonizing data from different vendorsDICOMImagingNormalized to uniform pixel depth，TextData采用ICD-11International Classification of DiseasesStandardEncoding。
03
Annotation Guideline Development
由Medical Experts制定Annotation Guide，明确EntityRecognition Standard（如DiseaseNameAnnotation需包含全称、别名及ICDEncoding）。Annotation Team需具备Medical背景，PassCase Study演练掌握BIOAnnotation法（Entity起始/internal/外部标记）And professional tool usage。
04
Multi-Modal Annotation Execution
Text Annotation：采用NER技术AnnotationMedical Record中的症状、DrugEntity，并建立症状-DiseaseRelated关系。
ImagingAnnotation：Polygon tool annotationOncology边界，Annotation病变Type及minlevel（如Pulmonary NoduleSize/密度）。
骨骼点Annotation：LocalizationJoint关键点，用于RehabilitationTrainingSolution制定。
05
Quality control and auditing
采用3-Tier QA机制：Annotation员自检（Accuracy Rate≥95%）、质检组抽样Examination（Recall Rate≥90%）、Medical Expert Final Review。Disputed cases require multidisciplinary consultation to determine annotation results。
06
DataDelivery与ModelTraining
OutputStructured DataSpec（如CSV/JSONFile）及配套Document，包含Data SourceExplanation、Annotation规则Version等。Delivery后需进rowModelVerify，如ImagingRecognitionModel需PassROC曲线AssessmentDiagnosis效能。
