Respiratory and Cardiac Function Analysis on the Basis of Dynamic Chest Radiography

摘要: Dynamic chest radiography with computer analysis is expected to be a new type of functional imaging system. This chapter presents computerized methods for quantifying and visualizing cardiopulmonary function on dynamic radiographs. The measurement parameters are diaphragm motion, heart wall pulmonary ventilation, blood circulation. We will first introduce evaluation items, physiology, diagnostic findings then describe image each item. pay particular attention interframe subtraction mapping technique, which play critical role in the ventilation also discuss features, future perspectives, issues related basis preliminary clinical study.
