5-4 Image Optimization
5.2 B Mode Image Optimization
B mode is the basic imaging mode that displays real-time images of anatomical tissues and
organs.
5.2.1 Basic Procedures for B Mode Imaging
1. Enter the patient information. Select an appropriate probe and exam mode.
2. Tap [B] on the right side of the operating panel to enter B mode.
3. Tap [Image] to open the image menu. Adjust the parameters to optimize the image.
4. Perform other operations (e.g., measurement and calculation) if necessary.
Tip: tap [B] to return to B mode at any time (except LVO mode).
5.2.2 B Mode Parameters
In B mode scanning, the image parameter area in the top-left corner of the screen displays the
real-time parameter values as follows:
Parameter F D G FR DR
Meaning Frequency Depth Gain Frame Rate Dynamic Range
5.2.3 B Mode Image Optimization
Frequency (Image Quality)
Description To switch between the fundamental frequency and harmonic frequency as well
as select the corresponding frequency type. The real-time frequency value is
displayed in the image parameter area in the top-left corner of the screen, and if
harmonic frequency is used “F H” is displayed as the harmonic frequency value.
Select the different frequency values through at the left part of the image
area.
The adjusting range of the harmonic frequency values can be divided into 4
levels: penetration preferred (HPen), general mode (HGen), resolution preferred
(HRes), and the mode between penetration preferred and general mode (HPen-
Gen).
The adjusting range of fundamental frequency values can be divided into 3
levels: penetration preferred (Pen), general mode (Gen), and resolution
preferred (Res).
Impacts The system provides an imaging mode 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.
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 top-left corner of the
screen.
