SSI-6000/SSI-5800/SSI-5500/SSI-5500BW
Digital Color Doppler Ultrasound System
7.3.8
DPI Power
POWER %
Similar to the acoustic output power in the B mode, the value of the output power
in the DPI mode should be kept as low as reasonably achievable.
• go to the DPI menu (
Figure 7.2
), highlight
POWER %
.
• use the
LEFT/RIGHT
keys to adjust the output power of the transducer.
Remark:
• The acoustic output power in the DPI mode is displayed on the screen at the
Color Image Info area (
PWR
).
7.3.9
Sector Width and Position
SEC.WIDTH
SEC.POS
Sector width and position are the same as those in the B mode, refer to
Section
: only this time you need to access the DPI menu (
Figure 7.2
) instead of the
B mode menu.
7.3.10
B Reject
B REJECT
Sets the display priorities of the color and 2D grayscale pixels. Larger B Reject
value suppresses more grayscale pixels.
• go to the context menu, highlight
B REJECT
.
• use the
LEFT/RIGHT
keys to adjust the B Reject value.
7.3.11
DPI Frequency
FREQUENCY
Similar to the CDI frequency, higher DPI frequency delivers better display of low
flow velocities, but the penetration depth is reduced. Lower DPI frequency delivers
better display of high flow velocities, but the penetration depth is increased.
• highlight
FREQUENCY
at the DPI menu.
• use the
LEFT/RIGHT
keys to adjust the frequency value.
Remark:
• The DPI frequency value is displayed on the screen at the Color Image Info
area (
FRQ
).
