Abstract
The present application relates to a method and system for generating multi-task learning-type generative adversarial network for low-dose PET reconstruction, and relates to the field of deep learning. The method includes connecting layers of the encoder with layers of the decoder by skip connection to provide a U-Net type picture generator; generating a group of generative adversarial networks by matching a plurality of picture generators with a plurality of discriminators in one-to-one manner; obtaining a first multi-task learning-type generative adversarial network; designing a joint loss functionfor improving image quality; and training the first multi-task learning-type generative adversarial network according to the joint loss functionin combination with an optimizer to provide a second multi-task learning-type generative adversarial network.
