The invention discloses a medical image intelligent diagnosis method and
system based on
deep learning, and relates to the technical field of medical iconography, and the method comprises the steps: receiving a multi-mechanism medical image with an initial diagnosis
label, and generating an enhanced sample according with anatomical features through an adaptive data enhancement module based on an anatomical structure according to organ partitions; a hierarchical
federated learning framework is established, a central
server cooperates with multi-mechanism edge nodes, the edge nodes
train an initial
deep learning model by using local data, a central aggregation gradient generates global parameter feedback, and iteration is performed until the model is converged; constructing an
annotation consistency evaluation module, carrying out secondary
annotation by the specialist physician, calculating a weighted Kappa coefficient and a Dice similarity coefficient, and if the index does not reach the standard, rechecking by a secondary and
primary physician; establishing an
annotation-model feedback
closed loop, and finely adjusting the local model by using recheck data; inputting a to-be-diagnosed image into the
global model, outputting a
lesion thermodynamic diagram, property probability distribution and confidence, and triggering manual review and outputting a feature analysis report when the confidence is low.
