B-mode parameter list
Item Functions
[Tx Level]
TX level settings
• Displayed in all modes.
[Focus Position]
Focal position setting for B-mode
• Shared with M-mode.
• The actual focal position depends on the transducer used.
[B Frequency]
Frequency setting for B-mode
• Shared with M-mode.
• For the parameter range, sequentially select all the frequencies that are available for the trans-
ducer.
[B Gain] Gain setting for B-mode
[Depth]
B and M image depth settings
• The maximum depth depends on the transducer used (or the exam type).
• Minimum depth values dier for each transducer.
[B DR] Dynamic range setting for B-mode
[FOV/POS]
Scan range setting for B-mode
• Controls the eld-of-view width of the transducer and increases the frame rate.
[FOV] : Control of the scan width (eld-of-view width)
[POS] : Controls the scan position when the scan width is less than 100 %
• Enabled when a convex transducer or a sector transducer has been attached to the system.
[LR Flip] Flip horizontal display setting for B images
[Rotate]
90° display rotation setting for B images
• M-mode is also simultaneously-operated (vertical ip for 180° and 270°).
[B Map] Map brightness curve setting for B-mode
[B Time Avg.] Persistence setting for B-mode
[Edge Enhance] Edge enhance setting for B-mode
[Simple Adjust]
The following adjustments are done in the relevant modes.
• Auto gain adjustment in B-mode
• Auto C ROI adjustment in Color Flow-mode/Power Doppler-mode/SCF-mode
• Auto Doppler gate adjustment in PW Doppler-mode
• Auto ow velocity adjustment in PW Doppler-mode/CW Doppler-mode/PW-TDI-mode
[S.Adjust Quit] Turns o automatic adjustment of image quality.
[B Color] Color setting for B-mode
[B Density]
Acoustic line density for B-mode
• Values that can be set dier depending on the transducer.
[Focus Pattern] Focal pattern numbers setting for B-mode
[Trapezoid]
Trapezoid display setting for B-mode
• Enabled when a linear transducer has been attached to the system.
[Zoom] B and M image zoom condition settings
[Zoom Ratio] B and M image zoom ratio settings
[B SI-Filter] Speckle noise reduction setting for B images
[Compound]
B image compound setting
• The set value varies according to the transducer used.
[Dual Layout]
Dual mode layout setting
• [U/D 1] : Dot-by-dot display
• [U/D 2] : Full screen display
