5.2.3 B Mode Image Optimization
Image quality
Description Used for switching B/THI and adjusting the frequency.The real-time value of frequency is
displayed in the image parameter area in the upper right corner of the screen, and if
harmonic frequency is used, “F H” is displayed as harmonic frequency value.
Operation
Press the knob under the [Image Quality] on the touch screen to switch B/THI.
Rotate the knob under the [Image Quality] on the touch screen to select the different
frequency values.
The adjusting range of THI frequency values can be divided into penetration preferred
(HPen), general mode (HGen), resolution preferred (HRes).
Under cardiac and cardiac-difficult mode, the values for SP5-1U can be arranged from
penetration preferred (HPen), general mode (HGen), between general mode and high
frame (HGen-FFR), resolution preferred (HRes), between the resolution and the high
frame (HRes-FFR).
The adjusting range of basic frequency values can be divided into penetration preferred
(Pen), general mode (Gen), resolution preferred (Res).
Impacts The system provides a THI function using harmonics of echoes to optimize the
image.Harmonic imaging enhances near field resolution and reduces low-frequency and
large amplitude noise, so as to improve small parts imaging.
Please select the frequency according to the detection depth and current tissue features.
Gain
Description To adjust the gain of the whole receiving information in B mode. The real-time gain value
is displayed in the image parameter area in the upper right corner of the screen.
Operation
Rotate <B> knob clockwise to increase the gain, and anticlockwise to decrease.
The adjusting range is: 0-100 in increment of 1.
Impacts Increasing the gain will brighten the image and you can see more received signals.
However, noise may also be increased.
Depth
Description This function is used to adjust the display depth of sampling, the real-time value of which
is displayed on the image parameter area in the upper right corner of the screen.
