TX level settings
• Displayed in all modes .
Focal position setting for B-mode
• Shared with M-mode .
• The actual focal position depends on the transducer used .
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 .
Gain setting for B-mode
B and M image depth settings
• The maximum depth depends on the transducer used (or the exam type) .
• Minimum depth values differ for each transducer.
Dynamic range setting for B-mode
Scan range setting for B-mode
• Controls the field-of-view width of the transducer and increases the frame rate.
[FOV] : Control of the scan width (field-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 .
Flip horizontal display setting for B images
90° display rotation setting for B images
• M-mode is also simultaneously-operated (vertical flip for 180° and 270°).
Map brightness curve setting for B-mode
Persistence setting for B-mode
Edge enhance setting for B-mode
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 flow velocity adjustment in PW Doppler-mode/CW Doppler-mode/PW-TDI-mode
Turns off automatic adjustment of image quality.
Color setting for B-mode
Acoustic line density for B-mode
• Values that can be set differ depending on the transducer.
Focal pattern numbers setting for B-mode
Trapezoid display setting for B-mode
• Enabled when a linear transducer has been attached to the system .
B and M image zoom condition settings
B and M image zoom ratio settings
Speckle noise reduction setting for B images
B image compound setting
• The set value varies according to the transducer used .
