Duplex Imaging

Duplex (Doppler) ultrasound image is a method of measuring the speed of blood flow in vessels using ultrasonic waves and a Doppler sensor. This method allows you to obtain a two-dimensional image of blood flow in different planes, as well as measure the speed of blood flow and its direction.

Duplex ultrasound scanning is used to evaluate blood flow in arteries and veins, especially in the heart and brain areas. It can be useful in diagnosing cardiovascular diseases such as atherosclerosis, hypertension and stroke.

Duplex ultrasound uses a special ultrasound transducer that sends sound waves to the area being examined. The reflected waves are captured by the sensor and converted into an image. The Doppler sensor then measures the speed of the blood based on its direction.

One of the advantages of duplex scanning is its high accuracy and the ability to obtain a three-dimensional image of blood flow. This allows doctors to more accurately diagnose vascular diseases and choose the most effective treatment methods.

Doplex imaging is a method of measuring blood flow velocity that is used to assess the condition of blood vessels and diagnose various diseases associated with blood circulation. This method is based on the use of ultrasonic waves that are reflected from moving objects, such as blood in vessels.

To conduct a duplex study, a special device is used - an ultrasound scanner, which generates sound waves and receives their reflection from tissues. The obtained data is processed by a special program that allows you to determine the speed and direction of blood movement in the vessels, as well as identify possible obstacles to blood flow.

The duplex view is especially useful in assessing the condition of the veins, as it can reveal the presence of blood clots, varicose veins and other diseases. In addition, this method can be used to determine the degree of arterial stenosis and evaluate the effectiveness of treatment.

Overall, duplex imaging is an important tool in the diagnosis and treatment of vascular diseases, and its application can significantly improve the quality of medical care.

There are a large number of methods for studying blood flow to diagnose diseases of the veins of the lower extremities and determine reflux in them. One of the fairly new methods is the Duplex Impedance Angiography (DIA) method, which allows you to visualize venous blood flow and simultaneously determine the speed of blood flow in the veins. This method is a combination of several special technologies, which ensures high quality research and more accurate diagnostic results.

The Duplex Impendansometry method takes into account the fact that blood has the properties of electrical capacitance. Its magnitude depends on the speed of blood flow (volume flow) in the walls of blood vessels. By measuring electrical resistance at points above the veins on various

Duplex imaging, also known as duplex (double) ultrasound, is an imaging technique that is used to determine the speed of blood flow in blood vessels. Unlike conventional ultrasound examinations (ultrasound), the duplex method combines two imaging methods: pulsed echolocation and spectral Doppler echolocation. This method can be used to determine venous and arterial blood flow, as well as to diagnose various cardiovascular diseases.

The operating principle of duplex imaging is based on the use of two types of ultrasound: pulsed and Doppler. Pulse echolocation creates sound waves that travel through tissue, and their reflection can be recorded by a sensor. Reflected sound is measured using digital ultrasound systems, which allows for high spatial accuracy and detail in the image of the object.

Spectral Doppler echolocation also uses sound waves, but they are created not at the emitter, but at the detector. These signals are further analyzed and converted into a spectrum, which makes it possible to determine the frequency of the reflected oscillations. This allows the speed of blood flow to be measured by analyzing the relationship between the speed of sound and the reflected vibrations in the sensor. Thanks to this method, we can determine the speed of blood flow at different levels of the cardiovascular system.

Duplex imaging is an important addition to conventional ultrasound (2D) imaging of blood vessels, allowing us to better understand their structure and function. For example, in the case of diseases of the liver, heart or arteries, this method helps to assess the degree of vascular damage, their patency, the presence of pathological changes, etc. Application of duplex methods
