Intended Use:
Doppler is intended to provide measurement data concerning the velocity of moving tissues and fluids. PW
Doppler lets you examine blood flow data selectively from a small region called the Sample Volume.
The X axis represents time while the Y axis represents velocity in either a forward or reverse direction.
PW Doppler is typically used for displaying the speed, direction, and spectral content of blood flow at
selected anatomical sites.
PW Doppler can be combined with B-mode for quickly selecting the anatomical site for PW Doppler
examination. The site where PW Doppler data is derived appears graphically on the B-mode image (Sample
Volume Gate). The Sample Volume Gate can be moved anywhere within B-mode image.
PW mode Exam Procedure:

Connect the appropriate system, leaving the systems in their respective holders.

Position the patient for the examination.

Press ID number and enter the appropriate patient data.

Select the application and system to be used.

Locate the anatomy to be examined. Get a good B-mode image. Press C - icon to help locate the vessel
you wish to examine.

Press PW - icon to display the sample volume cursor and gate.

Position or re-size the sample volume gate by moving the slide left, right, up and down.

Press PW - icon to display PW Doppler spectrum and the system operates in combined B+Doppler mode.
The Doppler signal is heard through the speakers.

Optimize the PW Doppler spectrum, as necessary.
