2D Mode
5.8 Transmitter
Focus
The selected focal zone determines the depth range of optimized sharpness of the ultrasound beam.
The
[
Foc#
]
field in the status area displays the actually set number of focal zones for transducers
which allow to change focal zones.
Use the
[
Foc
#
]
flip switch to select the number of focal zones.
The possible number of focal zones depends on the probe in use.
Arrows at the left side of the 2D image mark the active focal zones by their position.
Use the
[
Foc Depth
]
flip switch to select the depth position of the actual focus
zone(s). The depth position of the focal zone(s) is marked by the marker arrows.
Remarks:
*
After selection of focal zones the maximum possible acoustic output can be adequately reduced.
*
Changes are only possible in write mode.
*
The more focal zones that are set, the lower the frame rate.
5.9 Receiver
Frequency
Range
The “Frequency range” function allows for the fast adjustment of high resolution/ lower penetration,
mid resolution/ mid penetration, or lower resolution/ high penetration for the 2D image. From the
transducer's broadband signal a certain start frequency and start bandwidth is extracted and then
continuously changed over depth. Every transducer has a set of three fixed receive settings which are
easily controlled by using the
[
Frequency
]
flip switch.
Use the
[
Frequency
]
flip switch to adjust the range of the receive frequency.
Three positions are possible: Resolution, Normal, Penetration
Remarks:
*
The selected frequency range is displayed on the status area.
*
The frequency range is displayed in 2
nd
line of the B mode Image Info area:
e.g.:
7.5 - 5.0Mhz 7.5 ...... start frequency
