may appear on the LCD screen.
Table 6. Typical scanning scenarios and displays
SCANNING SCENARIO EXAMPLE DISPLAY DESCRIPTION
Optimal scan
In an optimal scan, the bladder is entirely contained
within the ultrasound field of view. The display shows:
• Bladder volume
• No > symbol
• No flashing arrow
• No solid arrow
Bladder volume is
greater than 999 mL
The bladder is entirely contained within the ultrasound
field of view but the bladder volume is greater than
999 mL. In this case, the display shows:
• A bladder volume of >999 mL
• No flashing arrow
• No solid arrow
Bladder is too large
to be fully contained
within the ultrasound
field of view
Either the bladder is too large to be contained by the
ultrasound field of view, or the user is pressing too hard
with the instrument. The display shows:
• Bladder volume with a > symbol
• No flashing arrow
• No solid arrow
Apply less pressure and rescan.
Bladder not centered
(optional rescan)
The bladder is entirely contained within the ultrasound
field of view but not centered. Rescanning is optional.
The display shows:
• Bladder volume
• A solid arrow indicating re‑aiming direction for
optional rescan
Move instrument in the direction of the arrow and rescan.
Bladder not centered
(rescan required)
Bladder is only partially contained within the ultrasound
field of view. A rescan is necessary to ensure accurate
bladder volume measurement. The display shows:
• Bladder volume
• A flashing arrow indicating the re‑aiming direction
Move instrument in the direction of the arrow and rescan.
