Abstract: A method and system for 3D reconstruction of coronary artery based on vascular branch registration. The method includes: classifying bifurcated vessels and normal vessels of an intravascular ultrasound image and segmenting intima and adventitia of the bifurcated vessels and normal vessels separately; extracting a 3D centerline of a CAG image; locating vascular branches and automatically matching key points of the CAG image; and registering the intima and adventitia segmentation images to the 3D centerline of the CAG image according to the key points of the CAG image and performing 3D reconstruction of the coronary artery. The method uses automatic matching of vascular branches to fuse CAG and IVUS images and reconstruct them in 3D, which is more helpful for intuitive judgment of doctors on the premise of improving speed and accuracy, and is of great significance for auxiliary diagnosis of diseases.

Abstract: A carotid artery ultrasonic examination report generation system which includes an ultrasonic device which acquires multi-modal information of a to-be-examined carotid artery; the processor is connected with the ultrasonic device, and includes: a plaque type recognition module that inputs multi-modal information into a plaque type recognition model to obtain the carotid artery's plaque type; an image division module inputs an ultrasonic image into different division models according to plaque type to obtain a divided image set; an abnormity detection module calculates image parameter set based on divided image set and input image parameter set into a carotid artery abnormity detection model to obtain a result indicating whether the carotid artery is abnormal; and a carotid artery ultrasonic examination report generation module generates a report based on the image parameter set, plaque type, blood flow spectrum pattern, blood flow kinetic parameters and result indicates whether the carotid artery is abnormal.

Abstract: An omni-bearing intelligent nursing system and method for a high-infectious isolation ward, including: a nursing robot, including a robot body and a controller; a plurality of collectors, arranged in the isolation ward and used for detecting the physiological index of the user and transmitting the physiological index to a remote control system; a communication network, in a star topology structure and including a plurality of communication modules, and configured to realize the communication of each the nursing robot, the collector and the remote control system; and the remote control system, receiving the information of the collector, performing feature extraction on the collect multi-element physiological signals, combining the basic information of the user, perform learning by a decision tree model, dynamically adjusting the corresponding nursing level, and sending an instruction to the corresponding nursing robot.
