[Screening chest X-ray examination with kinetic analysis using flat-panel detector].
We are developing dynamic screening radiography to provide kinetic information for lung respiratory examination using a flat-panel-detector (FPD) system. We modified the FPD system (CANON CXDI-22) to take sequential images for a short period of time (10 seconds, 3 frames/sec). Sequential chest radiographs from full inspiration to expiration were taken and analyzed for diaphragm movement and density changes in local lung areas to objectively detect respiratory anomalies. Our methods derived some respiratory functions such as regional air passage and lung structure movement, and suggested that the degree of chronic obstructive pulmonary disease and interstitial pneumonia could be evaluated quantitatively.
