CI Cephalic index. BPD/OFD.
cine A function that lets you review a series of previously scanned
images.
color box A box drawn on the scanned image that specifies the region
of the B-mode image for which color-coded flow information is
available in Color mode.
color Doppler See Color mode.
Color mode (CFM) Color-Flow Mapping (CFM). Real-time signal that represents
the speed of flowing material in each sample volume within
the Color mode scan area. The Color mode signal is in
principle independent of the amount of flowing material. The
Color mode is normally superimposed on a B-mode image
that shows the anatomical surroundings.
Flow directions towards and away from the transducer are
represented as different colors in Color mode (e.g. towards =
red, away = blue).
The Color mode signal (flow speed) is represented by
different values in the color mapping (relative measure) for
each sample volume in Color mode.
No color means either:
• No flow in the sample volume (very low flow speed) or
• Amount of reflection from flowing material (which might
have a high flow speed) is below threshold set by the
Color mode gain.
The Color mode signal (flow speed) is dependent on the
angle of the ultrasound beam relative to the flow direction.
combination mode Simultaneous scanning in more than one mode, for example,
B+Color or B+Color+Doppler.
control panel The part of the Pro Focus keyboard panel that contains the
special scanner control keys. For a description, see “The
Control Panel” on page 52.
CRL Crown rump length.
Doppler mode (Spectral) Doppler mode. This mode displays information
about the spectrum of flow velocities as a function of time. It
is sometimes called FFT (Fast Fourier Transform) because
the information is presented as a frequency spectrum
indicating velocity components.
duplex Simultaneous scanning in 2 modes. See combination mode.
ED End diastolic velocity.
