5 - 4 SONOACE X6 Operation manual

▐ Doppler Signal Adjustment

- During velocity measurement, an error may occur depending on the cosine angle

between the blood flow and the ultrasound beam.

- For Doppler velocity measurements, the most accurate results can be ensured when the

ultrasound beam is aligned in parallel with the blood flow.

- If that is not possible, the angle between them should be adjusted by using the Angle

option.

▐ Aliasing

- PW Spectral Doppler Mode uses a signal sampling technique to calculate the frequency

(or velocity) spectrum.

- Adjust the baseline or the velocity scale to minimize aliasing. A lower frequency probe

can also be used to reduce aliasing.

- Aliasing is dramatically reduced in CW Spectral Doppler Mode.

▐ Calculation Equation

- Some of the calculation equations used for clinical purposes originate from hypotheses

and approximation.

- All calculation equations are based on medical reports and articles.

▐ Human Error

- Human error may occur due to inappropriate use or lack of experience.

- This can be minimized through compliance with and thorough understanding of the

manuals.
