Abstract: A dynamic analysis system includes an imaging unit, an attenuation process unit and an analysis unit. The imaging unit images a dynamic state of a subject, thereby generating a plurality of frame images showing the dynamic state of the subject. The attenuation process unit performs an attenuation process to attenuate an image signal component of a product in the frame images. The analysis unit analyzes the dynamic state of the subject based on the frame images after the attenuation process.

Abstract: A radiographic image capturing device includes the following. A two-dimensional array of radiation detectors generate electrical charges corresponding to a dose of incident radiation. A control unit reads the electrical charges discharged from the radiation detectors in a form of image data. The control unit has radiographic modes including a still image mode for still image radiography, a moving image mode for moving image radiography, and a continuous radiographic mode for reading the image data without distinguishing between the still image radiography and the moving image radiography. The control unit selects the continuous radiographic mode to sequentially read the image data when an instruction on performing the still image radiography or the moving image radiography is not sent from an external control device or a user or when the radiographic mode is unknown due to communication failure with the external control device.

Abstract: Provided is a thoracic diagnosis assistance system. The system includes, an imaging unit, an extracting unit, a region dividing unit, an analysis unit and a display unit. The extraction unit extracts a lung field region from the plurality of successive image frames generated by the imaging unit. The region dividing unit divides the lung field region extracted by the extraction unit into a plurality of sub-regions and correlates the sub-regions among the plurality of image frames. The analysis unit performs an analysis of the sub-regions to calculate an inspiratory feature quantity and an expiratory feature quantity and to calculate a value of a ratio of the calculated inspiratory feature quantity to expiratory feature quantity and creates a histogram of the calculated ratio value. The display unit displays the histogram.
