• Analysis of Heart Beat Kinetics in Chest Screening Radiography by Dynamic Flat-panel Detector

抄録

It comes to be able to perform screening test which added functional information simply by using the modified flat panel detector(FPD). The purpose of this research is analyzing the dynamic state of heart wall from sequential chest images at the short period by the modified FPD. The heart beat process, peak expiratory and respiratory pause, was taken in three healthy volunteers and a patient of ischemic heart disease. Horizontal movement of heart wall in the left atrium, the left ventricle, and the cardiac apex part were analyzed for the sequential 30 images(6 frame/sec x 5sec). The result was approximated to the sign curve and amplitude(move distance of heart wall) and frequency(heart rate) were analyzed. Compared with the normal case, abnormal case's pulsation in the left ventricle and the cardiac apex part were small, and its cycle was also irregular than the analysis result. It is suggested that this method is useful as heart dynamic examination to diagnosis of angina, myocardial infarction, etc. which cause abnormalities of heart wall movement.
