A dynamic diagnosis support information generation system includes: a radiation generator capable of irradiating a pulsed radiation; a radiation detector which is provided with a plurality of detecting elements arranged in two-dimension, detects the pulsed radiation irradiated from the radiation generator at each of the plurality of detecting elements and generates frame images successively; and an analysis section which calculates and outputs a feature value relating to a dynamic image of a subject based on a plurality of frame images generated by radiographing the subject by using the radiation generator and the radiation detector, wherein the analysis section calculates the feature value relating to the dynamic image of the subject by corresponding pixels to each others representing outputs of a detecting element at a same position in the radiation detector among the plurality of the frame images.

Dynamic diagnosis support information generation system

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.

Thoracic diagnosis assistance system and computer readable storage medium

A chest diagnostic support information generation system includes: a radiography section which radiographs a chest portion of a subject; an image analysis section which generates a diagnostic support information based on an image data generated by the radiography section; and a display which displays the diagnostic support information, wherein the radiography section obtains a plurality of frame images which show a motion state of the chest of the subject, and the image analysis section includes: a breathing information generation section which generates the diagnostic support information relating to breathing of the subject based on a difference value of the pixel or the block corresponded with each other between image frames temporally adjacent among the plurality of frame images; and a blood flow information generation section which generates the diagnostic support information relating to blood flow of the subject based on a generated output signal wave form.

Chest diagnostic support information generation system

Provided is a diagnosis assistance system. The system includes, an imaging unit, an analysis unit, an operation unit, and a display unit. The analysis unit extracts a subject region from each of the plurality of image frames generated by the imaging unit, divides the extracted subject region into a plurality of regions, and analyzes the divided regions correlated among the plurality of image frames, thereby calculating a predetermined feature quantity indicating motions of the divided regions. The operation unit allows a user to select a region serving as a display target of an analysis result by the analysis unit. The display unit displays the calculated feature quantity regarding the selected region.
