  • Patent number: 10755395
    Abstract: An apparatus and method of denoising a dynamic image is provided. The dynamic image can represent a time-series of snapshot images. The dynamic image is transformed, using a sparsifying transformation, into an aggregate image and a series of transform-domain images. The transform-domain images represent kinetic information of the dynamic images (i.e., differences between the snapshots), and the aggregate image represents static information (i.e., features and structure common among the snapshots). The transform-domain images, which can be approximated using a sparse approximation method, are denoised. The denoised transform-domain images are recombined with the aggregate image using an inverse sparsifying transformation to generate a denoised dynamic image. The transform-domain images can be denoised using at least one of a principal component analysis method and a K-SVD method.

    Abstract: The present application relates to an image segmentation method and device operating on an electronic device. The image segmentation method comprises the following steps: performing deep learning to obtain an FCN (Fully Convolutional Network) model, and calculating the loss using L(pji)=?(1?pji)r log(pji) in the deep learning process; inputting an image to be segmented to the last updated FCN model to obtain the probability that each pixel in the image to be segmented is in each of the categories, and selecting the category corresponding to the maximum probability as the category determined by the image segmentation for the pixel. By improving the loss function of the FCN model, the accuracy of image classification is improved, and chart information in an electronic document is accurately extracted by means of pixel classification.

  • Publication number: 20200234471
    Abstract: A method and apparatus are provided for using a neural network to estimate scatter in X-ray projection images and then correct for the X-ray scatter. For example, the neural network is a three-dimensional convolutional neural network 3D-CNN to which are applied projection images, at a given view, for respective energy bins and/or material components. The projection images can be obtained by material decomposing spectral projection data, or by segmenting a reconstructed CT image into material-component images, which are then forward projected to generate energy-resolved material-component projections. The result generated by the 3D-CNN is an estimated scatter flux. To train the 3D-CNN, the target scatter flux in the training data can be simulated using a radiative transfer equation method.

  • Publication number: 20200202588
    Abstract: A method and apparatus is provided to iteratively reconstruct a computed tomography (CT) image using a spatially-varying content-oriented regularization parameter, thereby achieving uniform statistical properties within respective organs/regions and different statistical properties (e.g., degree of smoothing and noise level) among the respective organs/regions. For example, less smoothing and sharper features/resolution can be applied within a lung region than within a soft-tissue region by using a smaller regularization parameter value in the lung region than in the soft-tissue region. This can be achieved, e.g., using a minimum intensity projection to suppress/eliminate sub-solid nodules in the lung region. The content-oriented regularization parameter can be generated by reconstructing an initial CT image, which is then segmented/classified according to organs and/or tissue type.

  • Patent number: 10691582
    Abstract: The present disclosure describes methods and systems directed towards providing code coverage during software development. Implementation of code coverage assist developers in visualizing what portions of new code being developed can be tested via available tests as well as evaluating those portions of new code. The testing of the new code in this manner allows developers to understand whether portions of the new code have been developed properly. When the new code is determined to be satisfactory, via the tests and coverage, the new code can be incorporated into the master code branch. By testing the new code before merging, interruptions and downtime associated with the master code branch can be minimized.

  • Publication number: 20200175731
    Abstract: A method and apparatus is provided to reconstruct a computed tomography image using iterative reconstruction (IR) that is accelerated using various combinations of ordered subsets, conjugate gradient, preconditioning, resetting/restarting, and/or gradient approximation techniques. For example, when restarting criteria are satisfied the IR algorithm can be reset by setting conjugate-gradient parameters to initial values and/or by changing the number of ordered subsets. The IR algorithm can be accelerated by approximately calculating the gradients, by using a diagonal or Fourier preconditioner, and by selectively updating the preconditioner based on the regularization function. The update direction and step size can be calculated using the preconditioner and a surrogate function, which is not necessarily separable.
