Root Master

Aortic Valve Measurement Software



  • Aortic valve replacement surgery
  • Aortic valvuloplasty


Feature of Root Master

It is possible to evaluate the motion of aortic valve, which was conventionally measured with still images, with motion pictures now. The shape of aortic root is extracted from the ECG-gated enhanced CT image, and three-dimensional measurement of distance, valve circumference length, angle and area  is enabledat all time phases.

It can also follow an arbitrary section in one heartbeat and measure effective height and leaflet length in the reconstructed three dimensional space. It has a function to visualize valve shape and an arbitrary section by animation and it is useful for discussing the functional evaluation of valves.

Root Master is still improving day by day, and new functions implemented will be updated sequentially. However, originally it is designed to be used in the operating room, It is possible to operate with a relatively low-performance computer such as a notebook PC.
