9. Description of the ultrasound scanner's functions
9.1. Setting the parameters of imaging
9.1.1. Gain adjustment
Signal gain may be adjusted completely or in six horizontal image zones. It makes the structures displayed on
the screen lighter or darker.
In order to adjust gain completely:
1. Press ESC button.
2. Use the UP / DOWN arrows in order to adjust gain.
3. Conrm with the OK button.
In order to adjust gain in zones:
1. Open the menu and select TGC.
2. Use the UP / DOWN arrows to select the gain zone.
3. Use the LEFT / RIGHT arrows to adjust gain.
4. Conrm with the OK button.
9.1.2. Scanning depth adjustment
In order to adjust the scanning depth, use the LEFT / RIGHT arrows, where LEFT means scanning of shallowly
located organs, and RIGHT means scanning of deeply located organs.
The maximum scanning depth is 12 cm.
9.1.3. Focusing
The ultrasound scanner can change the level on which the ultrasound beam is focused the most. In order to
obtain the best eect, set the focusing level at the depth of the examined structure. In the focus the signal is
strongest, and image resolution is highest.
In order to set the beam focusing on the selected area, use the UP / DOWN arrows, where UP makes the beam
focus shallower, and DOWN — deeper.
9.1.4. Frequency
The probe connected to the iScan mini ultrasound scanner is a broadband, multi-frequency probe. Changing
the frequency of operation inuences the image resolution and the depth to which the ultrasounds penetrate
the body.
It is necessary to remember about the following principle:
1. Higher frequency = better resolution = lower ecient depth of scanning.
2. Lower frequency = worse resolution = higher ecient depth of scanning.
In order to change the frequency:
1. Open Menu and choose Frequency.
2. Use the UP / DOWN buttons to choose the most ecient frequency.
3. Conrm with the OK button.
