Abstract:
1. A chest diagnostic support information generation system comprising: a radiography section which radiographs a chest portion of a subject by using a radiation source and a radiation detector which generates an image data of the subject by detecting by a plurality of detection elements arranged two dimensionally, radiation having penetrated through the subject which is irradiated from the radiation source; an image analysis section which generates a diagnostic support information relating to the chest portion of the subject based on the image data generated by the radiography section; and a display which displays the diagnostic support information generated by the image analysis section, wherein the radiography section is structured to obtain a plurality of frame images which show a motion state of the chest of the subject by irradiating radiation continuously from the radiation source, and the image analysis section comprises: a breathing information generation section which, for the plurality of frame images obtained by the radiography section, corresponds a pixel or a block from each of the plurality of frame images with each other, wherein the pixel or block from each of the plurality of frame images represents signal values output by a detection element of a same position in the radiation detector among the plurality of image frames, and the breathing information generation section 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; and a blood flow information generation section which, for the plurality of frame images obtained by the radiography section, corresponds a pixel or a block from each of the plurality of frame images with each other, wherein the pixel or block from each of the plurality of frame images represents signal values output by the detection element of the same position in the radiation detector among the plurality of image frames, and the blood flow information generation section generates an output signal wave form which represents a temporal change of signal values of the pixel or the block corresponded with each other, and generates the diagnostic support information relating to blood flow of the subject based on the generated output signal wave form.
