  • Publication number: 20220309268
    Abstract: An attention mechanism-based 12-lead electrocardiogram (ECG) classification method is described, the method including acquiring an original image of a 12-lead ECG, segmenting waveform data recorded in the original image to obtain segmented waveform data for each lead in the 12-lead ECG, performing depth feature extraction on the segmented waveform data of said each lead to obtain a first feature map of said each lead, performing feature transformation on the first feature map of said each lead based on an attention mechanism to obtain a depth feature of said each lead, and classifying the depth feature of said each lead to obtain a classification result for the original image. The classification method can make full use of the 12-lead ECG for overall classification and improve the accuracy of image classification.

  • Patent number: 9583227
    Abstract: An optical device for focusing synchrotron radiation light source is disclosed according to the present invention, so as to improve the uniformity of the light intensity of the emergent light, to increase the divergence the emergent light, and to restrain the synchrotron radiation higher harmonics. An outline generatrix of the optical device is a quadratic curve segment or a combination of a plurality of quadratic curve segments, the opening orientations of which are the same, and the optical device includes: a plurality of capillary bodies made of transparent material, wherein the capillary bodies in a center region have a solid construe; the capillary bodies in a periphery region located outside of the center region have a hollow structure.
