  • Patent number: 11886311
    Abstract: The invention relates to a fault diagnosis method for a rolling bearing under variable working conditions. Based on a convolutional neural network, a transfer learning algorithm is combined to handle the problem of the reduced universality of deep learning models. Data acquired under different working conditions is segmented to obtain samples. The samples are preprocessed by using FFT. Low-level features of the samples are extracted by using improved ResNet-50, and a multi-scale feature extractor analyzes the low-level features to obtain high-level features as inputs of a classifier. In a training process, high-level features of training samples and test samples are extracted, and a conditional distribution distance between them is calculated as a part of a target function for backpropagation to implement intra-class adaptation, thereby reducing the impact of domain shift, to enable a deep learning model to better carry out fault diagnosis tasks.

  • Publication number: 20240029244
    Abstract: The present disclosure is directed to enhancing a lumen display in a CT sectional image of a blood vessel. The CT sectional image may be displayed with a first window level. An average CT value of lumen sections near the heart may be obtained, and a highest CT value of a section of a current blood vessel may also be obtained. A window level may be determined based on the average CT value and the highest CT value. At least a part of the section of the current blood vessel may then be displayed with the window level. The techniques allow for a window level to be preset to enhance lumen display and to improve the consistency of delineating the lumen contour, thereby avoiding deviations caused by subjective selection while saving time and improving patient flow.
