  • Publication number: 20240042204
    Abstract: This invention relates to a closed-loop adaptive AC stimulation neural network control method and system, involving the technical field of AC stimulation neural regulation. This system is composed of an individualized navigation module, AC stimulation module, EEG acquisition module and adaptive coupling module. After the magnetic resonance image and functional magnetic resonance image of the regulation object are input into the individualized navigation module, the functional connectivity network is generated to finalize regulatory targets. The position of stimulating electrodes and the magnitude of the stimulating current are determined according to the target to be regulated. The stimulating frequency is determined according to the EEG of the regulation object and then input into the AC stimulation module for regulation.

  • Publication number: 20220296304
    Abstract: A method and apparatus for evaluating aortic dissection surgery, an electronic device, and a storage medium are provided. The method comprises: obtaining a preoperative aortic model of a patient; simulating aortic dissection surgery on the basis of a virtual stent technology and the preoperative aortic model to obtain a postoperative aortic model; obtaining displacement amount of the same blood vessel node between the preoperative aortic model and the preoperative aortic model; and evaluating a surgical risk degree of the patient on the basis of the displacement amount. The occurrence probability of postoperative complications is related to the displacement amount.
