The invention relates to a deep
recurrent neural network-based cardiac function automatic
analysis method and belongs to the technical field of medical
image analysis. The method includes the following steps that: S1, a cardiac
nuclear magnetic resonance film is acquired, and the cardiac
nuclear magnetic resonance film is pre-processed; S2, a
recurrent neural network model of multi-
task learning is constructed, and underlying general image features are extracted; S3, the extracted underlying general image features are inputted into the two-layer long- and short-memory
recurrent neural network,space-time dependence relations are constructed; S4, a target
loss function is constructed; S5, and parameters in the recurrent neural network are trained and optimized through a stochastic gradientdescent method according to the
loss function constructed in step the S4; and S6, after the training of the
recurrent neural network model is completed, the pre-processed cardiac
nuclear magnetic resonance film is inputted into the trained recurrent neural network, and thirteen parameters in cardiac
function analysis are measured. With the method of the invention adopted, the manual delineation ofventricular structures is not required, and end-to-end cardiac
function analysis can be automatically performed.
