Chroma
Chroma is used to colorize the gray scale image to enhance the discrimination capability.
To adjust the chroma:
Tap the left or right part of Chroma on the touch screen to make a setting.
Compound Imaging
Compound imaging is used to acquire a series of overlapping image frames from
substantially differing spatial directions and combining these images to reduce speckle and
improve contrast resolution.
Tap Compound on the touch screen to enable or disable the compound imaging function.
Line Density
Line density refers to the amount of ultrasound beam that makes up the image. Increasing
the value of line density improves the resolution and decreases frame rate. Therefore, you
have to balance the frame rate and the image quality when adjusting the line density.
A higher line density is useful in obtaining a very high resolution, such as the thyroid or
testicles. A lower line density is useful when scanning fetal heart beat and adult cardiac
applications.
To adjust the line density
●
Tap the left part of Line Density on the touch screen to decrease the value.
●
Tap the right part of Line Density on the touch screen to increase the value.
Persistence
Persistence is used to average consecutive frames to provide a smoother appearance with
less noise. Use lower persistence values for fast-moving organs or tissues and higher
persistence values for a smoother appearance.
To adjust the persistence:
●
Tap the left part of Persist on the touch screen to decrease the value.
●
Tap the right part of Persist on the touch screen to increase the value.
Dynamic Range
Dynamic range increases the adjustable range of contrast by enhancing the intensities of
parts in the grayscale. It optimizes the ultrasound image texture.
To adjust the dynamic range:
●
Tap the left part of DYN on the touch screen to decrease the value.
●
Tap the right part of DYN on the touch screen to increase the value.
