Abstract
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.
