P11
Portable Digital Color Doppler Ultrasound System
6.3.9 Baseline
BASELINE
Shifting the baseline increases the velocity range in one direction, the zero position also
moves as a result. The maximum velocities in both directions are displayed at the ends of
the Spectral Wedge (15, Figure 2.4).
• go to the CDI menu (Figure 6.2), highlight BASELINE.
• use the
LEFT/RIGHT
keys to adjust the amount of the baseline shift.
6.3.10 Sector Width and Position
SEC.WIDTH
SEC.POS
Sector width and position are the same as those in the B mode, refer to Section 5.3.12 :
only this time you need to access the CDI menu ( Figure 6.2 ) instead of the B mode menu.
6.3.11 B Reject
B REJECT
Sets the display priorities of the color and 2D grayscale pixels. Larger B Reject value
suppresses more grayscale pixels.
The B Reject value is adjustable in the real time mode as well as the freeze mode.
• go to the context menu, highlight B REJECT.
• use the
LEFT/RIGHT
keys to adjust the B Reject value.
6.3.12 CDI Frequency
FREQUENCY
The CDI mode frequency controls the transmit frequency.
Higher frequency delivers better display of low flow velocities, but the penetration depth is
reduced.
Lower frequency delivers better display of high flow velocities, but the penetration depth is
increased.
• highlight FREQUENCY at the context menu.
• use the
LEFT/RIGHT
keys to adjust the frequency value.
 Remark:
• The CDI frequency value is displayed on the screen at the Color Image
Info area (FRQ).
6.3.13 Image Orientation (Left/Right)
LT↔RT
Refer to Section 5.3.16.
