  • Publication number: 20210100519
    Abstract: A non-transitory computer-readable storage medium storing a program causes a computer to perform an analysis process based on a radiation moving image in which a dynamic state of a specific site of a subject is captured. The program includes the analysis process in which, an analysis is performed based on the radiation moving image wherein when a plane in which the specific site is movable is to be a movable plane, the radiation moving image is obtained by irradiating radiation on the specific site in a state in which the radiation is orthogonal to the movable plane.

  • Publication number: 20200286235
    Abstract: A dynamic image analysis system includes a modality and a hardware processor. The modality generates first and second dynamic images each composed of frame images indicating dynamics of a subject. The processor detects a first signal value of a pixel in a first region in each of the frame images of the first dynamic image. The hardware processor detects a second signal value of a pixel in a second region in which an identical site to that of the first region is imaged, the second region being in each of the frame images of the second dynamic image. The processor determines an image processing condition for making the first signal value close to the second signal value based on the first and second signal values detected. The hardware processor performs image processing on the first dynamic image under the determined image processing condition to generate a processed dynamic image.
