Baseline: To adjust the 0cm/s baseline for better color and spectral display.
PRF: To adjust the speed scale for the color Doppler and spectral Doppler.
Correctional Angle: Adjust this button to optimize the spectral Doppler signal.
PWR DYN (20-200dB): Lower DYN for better contrast resolution, while higher DYN for better
detailed information.
Frequency: Lower FRE for better penetration in the far field, while higher FRE for better
resolution in the near field.
17. How to do the auto trace?
After pressing the button to activate the spectral Doppler, press to achieve automatic
envelope with or without freezing the image.
18. How to make the basic measurement in PW mode?
Place trackball on the PW graph, press to enter the basic measurement.
Basic Measurements including: velocity, time, HR, manual trace
19. How to make the special measurement in PW mode
When place trackball on the 2D image, calculation list will show measurements for 2D image.
Press , place trackball on the PW graph, move trackball to measurement list, choose cardiac
measurement.
Cardiac measurement – TEI, PHT, Mitral Valve, Tricuspid Valve, Pulmonary Valve, Aortic Valve.
SAVE AND REPORT
20. How to save images and cine?
After freezing the image, press to save the image, press for a while to save the
Cine.
21. How to make the measurement on the achieved image?
Press to enter Patient Exam List, find and open the achieved image by double click .
Press to make measurements. Use or to delete the last or all measurements.
