  • Publication number: 20220375086
    Abstract: According to one embodiment, a medical information processing method generates a high-contrast image by applying conversion processing to a first medical image captured by a first diagnostic apparatus and having a first contrast in a region of interest, the high-contrast image having a contrast higher than a contrast of a second medical image obtained by a second diagnostic apparatus. The method generates a pseudo second medical image by applying image processing to the high-contrast image, the pseudo second medical image simulating the second medical image and having a second contrast lower than the first contrast. The method trains a model using the pseudo second medical image as input data and the high-contrast image as ground truth data, and generates a trained model.

  • Publication number: 20220369904
    Abstract: An endoscope system that illuminates an object and captures reflected light from the object includes a control processor. The control processor acquires an examination image and determines whether the examination image shows a swallowing state or a non-swallowing state. In addition, the control processor detects a high pixel value region from the examination image and determines that the examination image shows the swallowing state in a case in which an area of the high pixel value region is equal to or greater than a first threshold value. Further, the control processor performs grayscale conversion on the examination image to obtain a grayscale image and performs a binarization process for obtaining the high pixel value region in a case in which a density value of a pixel of the grayscale image is equal to or greater than a second threshold value.

  • Patent number: 10736583
    Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry sets a first region of interest in a region corresponding to cardiac muscle on a cross-section of a heart included in image data. The processing circuitry further sets a second region of interest that is larger than the first region of interest in a region including the region. The processing circuitry determines a threshold for determining a range of signal values used for blood flow dynamic analysis on the image data based on a frequency distribution of signal values in the first region of interest. The processing circuitry carries out blood flow dynamic analysis on the second region of interest using signal values included in a range based on the threshold.
