1. Ultrasound Feature Overview: B-Mode (2D)
- The Basis of Ultrasound Imaging
In the process of performing an ultrasound technician scan, scanning in B-mode produces a
clear image. Thanks to the B-mode ultrasound, the information content has improved several
times. Currently, this method helps to visualize various organs and their individual structures in
a clear format.
B-mode designations
B-mode allows you to get a two-dimensional outline of an organ. The image on the screen is
obtained after reflection of the echo signal from the tissues. Its intensity is displayed by the
brightness of the dots in the resulting image. The signal is analyzed by the instrument in terms
of amplitude and phase. The method is the main one if you want to identify the structure,
pathology of blood vessels, internal organs.
B-mode options
What is B-Mode Ultrasound? This is a one minute update of 20 frames in grayscale. Each of
them has its own wave amplitude.
Optimal B-mode setting
To get an optimized image, you need to adjust the following settings:
Freeze - switching Real time / Freeze frame;
cine loop;
depth;
position and quantity;
gain (Gain), including in depth;
image optimization in automatic mode;
sector size;
scan frequency;
harmonic image;

2. multipath scanning.
How a B-Mode Image is Formed
A full-featured ultrasound technician system generates an image as it receives data from the
transducer. When the sound wave is completely reflected, it is visible on the screen in the form
of white, and if it passes through the tissues, then in the form of black. The resulting black and
white image is well perceived by the eye, no worse than color. Any physiological features,
pathological changes are clearly distinguishable.
Why B-mode settings get lost
Ultrasound 2 d is used more often than others. Almost before each study, it is required to adjust
the device in order to obtain a better image. Reconfiguration helps to change deep system
indicators. It should be borne in mind that the following can affect the lack of preservation of
previously made settings:
rebooting the device without previous proper shutdown;
incorrect disconnection directly from the power supply;
fluctuations in the power supply.
Accuracy in the settings is necessary if several specialists work on the same device.
What functions are taken into account when working
The following functions are taken into account when setting:
size areas;

3. depth;
number;
focus position;
Depth Gain Compensation (TGC);
gain.
Sometimes other parameters are taken into account, for example, tissue harmonic functions,
optimization of the resulting image in automatic mode. Together, these parameters, when
properly combined, contribute to obtaining clear images that help to make an accurate
diagnosis.
Combination of ultrasound with other diagnostic methods
Ultrasound is successfully combined with other instrumental research methods. Only some
preparatory measures for them can reduce the information content of ultrasound
diagnostics. Therefore, it is recommended to go on another day:
studies using barium suspension;
laparoscopy;
laparotomy.
X-ray diagnostics is well combined with ultrasound and can be performed on the same day
alternately.
