Description

technical field [0001] The present invention relates to the field of medical images, in particular to a lung segmentation-based optimization method and system for lung lobe segmentation. Background technique [0002] In the field of medical images, due to the difficulty in obtaining training data, it is often difficult to train the neural network to the optimal state, which will lead to inaccurate prediction results. Due to the difficulty of delineating lung lobes, only a small number of training samples can often be obtained. Therefore, it is usually necessary to post-process the lung lobes to minimize the errors in the prediction results. Compared with the lung lobes, the lungs are much less difficult to draw because of their clearer boundaries, and it is much easier to obtain training data. At the same time, due to the clear boundary characteristics of the lungs, the training of the neural network is also easier, and the prediction results will be more accurate. [0003]...
