A method for transforming and segmenting medical volumes based on generating an antagonistic network

Abstract

A method for transforming and segmenting medical volumes based on generating an antagonistic network mainly comprises the acquisition of synthetic data, the interaction between a generator and a segmentation device, the complete target and the architecture of the antagonistic network and the process is that firstly, the generator is trained with the cyclic consistency loss function of the antagonistic network to compulsorily reconstruct the synthetic data so as to reduce the geometrical distortion of the synthetic image; then, two auxiliary maps, namely segmentation devices, are used to control the geometrical invariance of the synthesized data, so as to ensure the shape consistency of the synthesized image, and finally, the segmentation devices are amplified with the synthesized data generated in the generator to become the multi-mode segmentation devices to achieve efficient volume segmentation. Compared with the traditional method, the method can learn unpaired data, achieves the consistency of image set shapes and improves the segmentation efficiency by using synthetic data, thus achieving the goal of synthesizing clear 3D medical images efficiently.
