Pulse Inversion Harmonic (tissue inverse harmonic) is a technology for extracting the harmonic component of internal organ oscillations caused by the passage of basic and inverse ultrasonic pulses through a body. A signal obtained by adding the base and inverse components of the reflected signal is considered useful. As a rule, the inverse harmonic (compared to the direct harmonic) provides the best quality, because both signals (basic and inverse) pass through the body and when added, noise is automatically filtered. The most appropriate application of inverse harmonic technology in the study of moving tissues (vessels, heart) and hardly-visualizable tissues (with similar acoustic density), such as tumors.

Power doppler (energy doppler) - a qualitative assessment of low-speed blood flow, used in the study of a network of small vessels (thyroid, kidney, ovary), veins (liver, testicles), etc. More sensitive to the presence of blood flow than color doppler. On the echogram is usually displayed in an orange palette, brighter shades indicate a greater speed of blood flow. The main drawback is the lack of information about the direction of blood flow. The use of a power doppler in three-dimensional mode makes it possible to judge the spatial structure of the blood flow in the scanning area.

Pulse Wave Doppler (Pulsed Wave Doppler) - used to quantify the blood flow in the vessels. The time sweep vertically displays the flow rate at the point of interest. Flows that move to the sensor are displayed above the baseline, reverse flow (from the sensor) is lower. The maximum flow rate depends on the depth of the scan, the frequency of the pulses and has a limit (about 2.5 m / s in the diagnosis of the heart). High-frequency pulse doppler (HFPW - high frequency pulsed wave) allows you to record the flow rate of higher speed, but also has a limitation associated with the distortion of the Doppler spectrum.

Color Doppler Flow Imaging (Color Doppler) - selection on the echogram color (color mapping) nature of the blood flow in the area of ​​interest. The blood flow to the sensor can be mapped in red, from the sensor - in blue. Turbulent blood flow is mapped in blue-green-yellow. Color doppler is used to study blood flow in the vessels, in echocardiography. Other technology names include color Doppler mapping (DDC), color flow mapping (CFM) and color flow angiography (CFA).

Continuous Wave Doppler or CW (Continuous, Constant-Wave Doppler) is used to quantify blood flow in vessels with velocity streams. The disadvantage of the method is that the flows are recorded integrally, i.e. across the depth of the scan. In echocardiography, using continuous doppler, it is possible to calculate pressure in the cavities of the heart and the great vessels in one or another phase of the cardiac cycle, calculate the degree of significance of stenosis, etc. The basic equation for CW is the Bernoulli equation, which allows to calculate the pressure difference. Using this equation, it is possible to measure the pressure difference between the chambers in normal conditions and in the presence of abnormal high-speed blood flow.

Tissue Harmonic Imaging (THI, tissue or 2nd harmonic) is a technology for extracting the harmonic component of internal organ oscillations caused by a basic ultrasound pulse passing through the body. Considered useful signal obtained by subtracting the base component from the reflected signal. The application of the 2nd harmonic is advisable for ultrasound scanning through tissues intensively absorbing the 1st (base) harmonic. This technology involves the use of broadband sensors and receiving path
hypersensitivity. Improved image quality, linear and contrast resolution in patients with overweight.
