VFI - Vector Flow Imaging

Puncture

Artifacts

WARNING

VFI-w1

Before you turn on VFI, check the B-mode image to make sure there are no artifacts visible
in the blood vessel. If there are strong artifacts in the B-mode image, the arrows in VFI may
be pulled to point in a more axial direction (toward or away from the transducer),
especially in low flow situations with correspondingly low PRF. These artifacts will not
affect the color mode (CFM) image, so it is important to check in B-mode.

Arrow

aliasing

WARNING

VFI-w2

Check to make sure the VFI arrows are not aliasing before you activate the assisted
Doppler gate placement. Otherwise, the Doppler gate will not be positioned correctly.

Diameter

markers

WARNING

VFI-w3

Check to make sure that the diameter markers correspond to the inner vessel wall and that
the connecting line between the markers is perpendicular to the direction of the vessel.
Otherwise, the real-time volume flow measurement may not be precise.

Doppler gate

large

enough

WARNING

VFI-w4

Check to make sure that the Doppler gate covers the entire vessel. Otherwise, the real-
time volume flow measurement may not be precise.

Doppler gate

over only

one vessel

WARNING

VFI-w5

Check to make sure that the Doppler gate only covers one vessel. Otherwise, the real-time
volume flow measurement may not be precise.

Doppler

spectrum

aliasing

WARNING

VFI-w6

Check to make sure that the Doppler spectrum does not alias. Otherwise, the real-time
volume flow measurement may not be precise.

Verify

transducer

type number

WARNING

P-w1

Before you start imaging, verify that the type number or name of the transducer and the
type number or description of the needle guide you are using match the number
displayed on the monitor. Also make sure that the needle guide is positioned correctly. If
the numbers do not match, or if the needle guide position is not correct, the puncture line
on the monitor may not correspond to the true puncture path in the tissue. In case of any
inconsistency, stop imaging, turn off the system, and contact your BK service
representative.
