8. Press SET. The measurement end point is anchored and
the RVIDs measurement value is displayed in the
Measurement result table.
A new free-moving cursor is displayed on the image, ready
for the next measurement.
9. Repeat steps 5, through 8 to measure RVIDs.
Both the RVIDd and RVIDs values are displayed in the
Measurement result table.
Doppler Measurements
The following measurements may be calculated on Doppler
mode spectra:
For measurement
formulae, refer to
the Reference
Manual.
• Maximum (peak) and mean velocity
• Maximum and mean pressure gradient
• Pressure half-time (PHT)
• Velocity time integral (VTI)
• Mitral valve area (MVA), derived from PHT
Velocity and Pressure point measurements
