The present application relates to a kind of synthesis method and electronic equipment of coronary artery CCTA image, comprising: obtaining the image of paired NCCT and CCTA, after pretreatment, obtain high consistency image training pair;LDM model suitable for adapting coronary artery image synthesis is constructed, the LDM model includes frozen variational autoencoder, the denoising U-Net of trainable based on cross attention mechanism, and decoder, the denoising U-Net integrates ResNet2D module, Transformer2D module and multi-scale cross attention layer;After pre-processing, the NCCT image to be processed is input into the LDM model trained, and the latent representation of CCTA image is generated by the reverse diffusion denoising process in latent space, and finally the high-resolution Syn-CCTA image is output by decoder.Compared with prior art, the present application has the advantages of no contrast agent to realize coronary artery CCTA image with auxiliary diagnostic value.

The present disclosure provides a game control method and an electronic device, by setting a first control and controlling the controlled virtual object to sequentially execute different flight states based on different operation and release operation, one-stop control of all flight states by single control is realized; since the player only needs to press, release and trigger the same control to complete the flight cycle, the control threshold of multi-finger and multi-control coordination is significantly reduced, and the smoothness and convenience of the interactive experience are improved. At the same time, the introduction of the level flight state enables the controlled virtual object to maintain the current flight height in the air, providing the player with stable air stay and observation of the environment, thereby expanding the interactive space dimension in the virtual scene and improving the game richness and strategy depth.
