■ The values such as PSV, EDV, Vmean, Gmean, Gpeak, S/D, PI, RI, etc. can be

obtained from the spectral waveform in Spectral Doppler Mode. There are four

measurement methods: Auto Trace, limited Trace, Manual Trace, and Measurement

Each Item One by One. For more information, refer to ‘Doppler Spectrum

Measurement Method’.

■ Stenosis % Calculation : There are two ways to obtain the Stenosis % of each

vascular system: %StA using the area and %StD using the distance. Refer to ‘Volume

Flow Measurement’ for more information.

■ Vessel Area Measurement: There are two ways to obtain Vessel Area: Vesl. Area

using the circumference and Vesl. Dist using the distance.

■ The user can obtain the Volume Flow values using the TAM (Time Average Mean

Velocity) value obtained from the spectral waveform and the Vessel Area value

obtained using Vesl. Area or Vesl. Dist.
