CT image new coronal pneumonia area segmentation method and imaging method

The invention discloses a CT image new coronal pneumonia region segmentation method. The method comprises the steps of obtaining a new coronal pneumonia CT image data set with a label label and processing the new coronal pneumonia CT image data set to obtain a training data set; constructing a CT image new coronal pneumonia region segmentation preliminary model; constructing an auxiliary classification network; based on the auxiliary classification network, training the CT image new coronal pneumonia region segmentation preliminary model to obtain a CT image new coronal pneumonia region segmentation model; and adopting the CT image new coronal pneumonia region segmentation model to complete new coronal pneumonia region segmentation of the actual CT image. The invention further discloses an imaging method comprising the CT image new coronal pneumonia region segmentation method. According to the method, more complete region information can be captured, the difference between a prediction map and a label can be
