Effect of valve profiling and increasing kVp on in situ radiographic detection of single leg separations of the Bjork-Shiley Convexo-Concave heart valve

摘要

Optimal imaging profiles and the advantages of higher kVp were established experimentally for imaging of single leg separations in Bjork-Shiley Convexo-Concave heart valves using a phantom simulator. These techniques were applied in a subsequent clinical study, which demonstrated the feasibility of in situ radiographic single leg separation detection.
