  • 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.

  • Publication number: 20200196973
    Abstract: A deep learning (DL) network reduces artifacts in computed tomography (CT) images based on complementary sparse-view projection data generated from a sparse kilo-voltage peak (kVp)-switching CT scan. The DL network is trained using input images exhibiting artifacts and target images exhibiting little to no artifacts. Another DL network can be trained to perform image-domain material decomposition of the artifact-mitigated images by being trained using target images in which beam hardening is corrected and spatial variations in the X-ray beam are accounted for. Further, material decomposition and artifact mitigation can be integrated in a single DL network that is trained using as inputs reconstructed images having artifacts and as targets material images without artifacts with beam-hardening corrections, etc. Further, the target material images can be transformed using a whitening transform to decorrelate noise.

    Abstract: A deep learning (DL) network corrects/performs sinogram completion in computed tomography (CT) images based on complementary high- and low-kV projection data generated from a sparse (or fast) kilo-voltage (kV)-switching CT scan. The DL network is trained using inputs and targets, which respectively generated with and without kV switching. Another DL network can be trained to correct sinogram-completion errors in the projection data after a basis/material decomposition. A third DL network can be trained to correct sinogram-completion errors in reconstructed images based on the kV-switching projection data. Performance of the DL network can be improved by dividing a 3D convolutional neural network (CNN) into two steps performed by respective 2D CNNs. Further, the projection data and DLL can be divided into high- and low-frequency components to improve performance.

    Abstract: An imaging apparatus includes an angular velocity sensor that detects a shake and a motion vector detection unit that detects a motion of a subject, and optically corrects an image blur by moving a shift lens. In a mode for supporting panning imaging, a shutter speed calculation unit calculates first and second exposure times as an exposure time of an imaging element. The first exposure time is calculated using a shake detection signal, a motion amount of a subject image, a focal distance of an imaging optical system, and a set value of a flow effect of a background image. The second exposure time is calculated from the shake detection signal, the motion amount of the subject image, a position and a maximum correction angle of a shift lens. If the first exposure time exceeds the second exposure time, processing of preferentially determining the second exposure time is performed.

  • Patent number: 10691036
    Abstract: An image forming apparatus can inhibit an occurrence of downtime or shorten the downtime even in a case in which a mode for performing image formation and a position of, for example, a primary transfer member does not match. The image forming apparatus includes photosensitive drums each configured to bear a toner image, primary transfer members, an intermediate transfer belt, an abutment/separation mechanism configured to move the primary transfer members, and a controller. The controller brings the primary transfer members into contact with the photosensitive drums in a full-color mode, separates the primary transfer members from the photosensitive drums in a monochrome mode, and sets the position of the primary transfer members to a predetermined position between that in the full-color mode and the monochrome mode in a standby mode.
