5-18 Image Optimization
T/F Res
Description
This function is used to adjust for a balance between time resolution and
spatial resolution.
Operations
Adjust through the [T/F Res] item on the image menu.
Dynamic Range
Description
The dynamic range conveys the information that being transformed from echo
intensity to gray scale.
Operations
Adjust through the [Dynamic Range] item on the image menu.
Effects
The more the dynamic range, the more specific the information, and the lower
the contrast with more noise.
HPRF
Description
HPRF mode is used when detected velocities exceed the processing
capabilities of the currently selected PW Doppler scale, or when the selected
anatomical site is too deep for the selected PW Doppler scale.
Operations
Turn on or off the function through the [HPRF] item on the image menu.
Effects
HPRF enhances the range of detecting high-velocity flow.
Speed
Description
This function is used to set the scanning speed of PW mode imaging.
Operations
Click the [Speed] item on the image menu.
The smaller the value the faster the speed.
Effects
Changing the speed makes it easier to identify the cardiac cycles and to
detect more details.
Display Format
Description
To set the display format of PW mode image with B mode image.
Operations
Click the [Display format] item on the image menu to adjust.
Options: V2:1, V1:2, V1:1, Full.
Audio
Description
This function is used to adjust the output audio in spectrum map.
Operations
Click the <Audio> item on the image menu to adjust the volume.
Effects
Utilizing the output audio helps to identify the feature and status of flow.
Colorize and Colorize Map
Description
Colorize function provides an imaging process based on color difference rather
than gray distinction.
Operation
Turn on or off the function through the [Colorize] item in the menu;
Select the colorize map through the [Colorize Map] item in the menu;
Impacts
The function is available in real-time imaging, freeze or cine review status.
