Acoustic evaluation of progressive failure in BSCC heart valves pp. ... Multiple feature acoustic classification of BSCC artificial heart valves pp.
Sounds and vibrations produced by prosthetic heart valves may reflect the structural and functional integrity of their components. In fact early signs of valve ...
The primary techniques evaluated included analyzing acoustic signals from the valves, imaging valves for potential cracks in the struts, and structural analyses ...
We developed a time-windowed, power density analysis of C/C valve closing sounds to detect the vibrational resonance that characterizes the presence of an ...
Missing: progressive BSCC
The ideal condition for detecting defects in BScc valves by X-ray or acoustic analysis [1,9] is the presence of 'some dis- placement of fracture ends with close ...
