Using nature that a pixel value in a lung of a chest X-ray moving image varies due to heart beat, the variation information on the pixel value is effectively used for diagnosis such as of a lung embolism or a heart disease, considering the variation information as lung blood flow information. A continuous X-ray image screening examination device receives a chest X-ray moving image from an X-ray detector and receives an electrocardiogram to become original information on a heart beat variation from an electrocardiogram recording apparatus. From the dynamic state of the heart wall measured by the electrocardiograph or the chest X-ray moving image, the heart dynamic state during the cardiac chamber systolic and diastolic phases is grasped, and information such as the variation of the pixel value of the chest X-ray moving image due to increase (lung blood flow increase) of the blood flow from the heart to the lung during the cardiac chamber systolic phase is generated.
A continuous X-ray image screening examination device to which an X-ray moving image of an examinee is input and which generates information for assessing blood flow with the X-ray moving image, wherein the X-ray moving image is generated without a contrast agent characterized by comprising
A continuous X-ray image screening examination program using an apparatus comprising an image store configured to store a plurality of frames, said plurality of frames configuring an X-ray moving image of an examinee, to generate information for assessing blood flow with the X-ray moving image, wherein the X-ray moving image is generated without a contrast agent, the program causing a computer configuring the apparatus to execute
