Figure 1:

Transcatheter heart valves scanned ex vivo in ultra-high-resolution (UHR) mode with photon-counting detector CT. Four different ex vivo transcatheter heart valves were scanned in UHR mode with 140 kV and reconstructed with a Qr89/Qr76 kernel at quantum iterative reconstruction strength 4. CT images are displayed as three-dimensional volume-rendered images: (A) CoreValve Evolut R (Medtronic), (B) JenaValve (JenaValve Technology), (C) Lotus Edge (Boston Scientific), (D) SAPIEN 3 Ultra TM transcatheter heart valve (Edwards Lifesciences).
