  • Publication number: 20250120614
    Abstract: An acquisition unit acquires image data indicating at least a chest and an abdomen of a test subject. A detection unit detects the displacement of each of the chest and abdomen of the test subject by using the image data. A display control unit performs control so that the movement image of each of the chest and abdomen is displayed based on the detected displacement of the chest and abdomen. When the movement of the chest and the movement of the abdomen are synchronized with each other, the display control unit performs control so that the display form of the chest movement image and the display form of the abdomen movement image are the same as each other.

  • Publication number: 20240212103
    Abstract: To provide an information processing apparatus and the like that are capable of dividing an image indicating movement of a subject into a chest region and an abdominal region along anatomical knowledge. The information processing apparatus inputs time-series distance image data acquired by measuring a distance from a subject during a breathing exercise. The apparatus calculates a standard deviation image indicating a standard deviation of values for each pixel in a distance image indicated by the time-series distance image data. The apparatus executes division processing of dividing the standard deviation image into the chest region and the abdominal region of the subject by using a differential value in a direction of an intersection line between a sagittal plane and a frontal plane of the subject with respect to the standard deviation image. The apparatus outputs a result of the division processing by superimposing the result on the standard deviation image.
