P11
Portable Digital Color Doppler Ultrasound System
• highlight GSC in the context menu.
• use the
LEFT/RIGHT
keys to decrease/increase the value of Grayscale Curve.
Remarks:
Grayscale Curve is displayed at the 2D Image Info area on the screen (The
G in D/G).
5.3.10 Persistence
PERSIST
Adjust the persistence value to remove speckles from 2D images and enhance the smooth-
ness of the image.
• go to the B mode menu (Section 5.3.1), highlight PERSIST.
• use the
LEFT/RIGHT
keys to decrease/increase the value of Persistence value.
Remarks:
Persistence value is displayed at the 2D Image Info area on the screen
(The P in I/P).
5.3.11 Chroma
CHROMA
The echo amplitudes are converted to pixels with different brightness. The chroma value
(color tone and saturation) is mapped to the pixels. There are 13 map combinations
available.
The chroma value is adjustable in the real time mode as well as the freeze mode.
• highlight CHROMA in the context menu.
• use the
LEFT/RIGHT
keys to change the chroma value.
5.3.12 Sector Width and Position
User can reduce the imaging area to the region of interest by reducing the sector width and
move the sector position.
SEC.WIDTH
To change the sector width:
• go to the B mode menu (Section 5.3.1), highlight SEC. WIDTH.
• use the
LEFT/RIGHT
keys to decrease/increase the sector width.
SEC.POS
To move the sector position:
• go to the B mode menu (Section 5.3.1), highlight SEC. POS.
• use the
LEFT/RIGHT
keys to move the imaging sector to the left or right.
5.3.13 Line Density
LINE DENSITY
LINE DENSITY
can be set to Low, Medium or High. Higher line density can provide better
horizontal resolution, but also reduces the frame rate.
• go to the B mode menu (Section 5.3.1), highlight LINE DENSITY.
• use the
LEFT/RIGHT
keys to change the line density setting.
