. B-mode ultrasound is one of the most commonly used operation modes of a clinical ultrasound machine.As explained earlier, ultrasound is a reflection or scattering based imaging modality, and the sophisticated generation of a sound wave allows the focusing of the sound to a specific location B-Mode is a two-dimensional ultrasound image display composed of bright dots representing the ultrasound echoes. The brightness of each dot is determined by the amplitude of the returned echo signal. This allows for visualization and quantification of anatomical structures, as well as for the visualization of diagnostic and therapeutic procedures
B-mode or 2D mode: In B-mode (brightness mode) ultrasound, a linear array of transducers simultaneously scans a plane through the body that can be viewed as a two-dimensional image on screen. More commonly known as 2D mode now. B-flow image of venous reflux. B-flow is a mode. B-Mode, or Brightness Modulation, is the display of 2D map of B-Mode data, and is the most common form of ultrasound imaging. Unlike A-Mode, B-Mode is based on brightness with the absence of vertical spikes. Therefore, the brightness depends upon the amplitude or intensity of the echo. There is no y axis on B-Mode, instead, there is a z axis.

B-mode: ( mōd ), A two-dimensional diagnostic ultrasound presentation of echo-producing interfaces; the intensity of the echo is represented by modulation of the brightness of the spot, and the position of the echo is determined from the angular position of the transducer and the transit time of the acoustical pulse and its echo 2.M-mode or motion mode 3.Colour flow doppler imaging 4.Pulse wave doppler 5.Continuous wave doppler 6.Tissue doppler . 2D. This is the default mode that comes on when any ultrasound / echo machine is turned on. It is a 2 dimensional cross sectional view of the underlying structures and is made up of numerous B-mode (brightness mode) scan lines B-Mode (Brightness) B-mode converts echo amplitude into grey scale to produce an image and is what most people think of when they think about ultrasound imaging. B-mode produces 2D images of underlying anatomy in near real time B-mode. The B-mode is a two-dimensional (2D) image of the area that is simultaneously scanned by a linear array of 100-300 piezoelectric elements rather than a single one as in A-mode (Figure 9). The amplitude of the echo from a series of A-scans is converted into dots of different brightness in B-mode imaging
By making the ultrasound beam sweep over a sector, the image can be made to build up an image, consisting of multiple B-mode lines. c. In principle, the image is built up line by line, by emitting the pulse, waiting for the reflected echoes before tilting the beam and emitting the next pulse B-mode formats The B-mode image, just described, was produced by a linear transducer array, i.e. a large number of small transducer elements arranged in a straight line (see Chapter 3). The ultrasound beams, and hence the B-mode lines, were all perpendicular to the line of transducer elements, and hence parallel to each other (Figure 1.4 a) (The approximation in case B is small, the velocity of ultrasound in tissue is 1540 m/s, while the velocity of blood is between 0,2 and 6 m/s, and tissue between 0.05 and 0.2 m/s, giving a v/c of maximum 0.004, i.e the approximation in B is maximum 0.4% and in reflected ultrasound 0.2%)
Typical time-averaged intensities at the location in the ultrasound beam where the maximal values are found are on the order of 10 to 20 mW/cm 2 for B-mode imaging. Doppler and color flow imaging modes have higher duty factors. Moreover, these modes tend to concentrate the acoustic energy into smaller areas B-mode, or bright mode, is now often referred to as 2D ultrasound.This is the mode of scanning that is most often associated with clinical ultrasound imaging Most of ultrasound medical imaging systems currently on the market implement standard Delay and Sum (DAS) beamforming to form B-mode images. However, image resolution and contrast achievable with. M-mode (ultrasound) Patrick O'Shea and Dr David Carroll M-mode provides not only excellent temporal resolution but superior axial resolution to B-mode (i.e. the ability to discern non-contiguous structures in a vertical plane). Clinical use. M-mode is utilised for its aforementioned superlatives;. B-mode ultrasound: In ultrasonography, a display that uses dots of differing intensities to represent echoes received from tissues that more strongly or weakly reflect sound waves.
